kenaf fiber reinforced composites: a review

The combination of natural fibers with synthetic fibers in hybrid composites has become increasingly applied in several different fields of technology and engineering. Natural fibre is a well-known reinforcement fibre in polymer-matrix Composites (PMC) lately. The core is a wood-like structure that makes up the remaining 60–70% of the weight. Review Kenaf ï¬ber reinforced composites: A review H.M. Akilâ, M.F. The decreased from 172°C to 162°C, 155°C and 150°C for neutral, acidic and alkaline solution, respectively. Kenaf fiber is unique and potentially reliable. Therefore conventional engineering fibres such as glass and carbon fibres, gradually substituted by natural fibre and sometimes use along with mineral fillers to meet the specification of certain task [9]. Most of the natural fibres were implemented in daily life in Egypt from about 7,000 years ago [11]. The papers made are stronger, whiter, of higher duration for yellowing resistance, and smoother for printing [14–16]. The most important criteria are the ignition time, rate of propagation, and fire behavior. Rouison et al. Y. Fortunately, they have a very low probability of becoming uncontrolled in-flight fires. Therefore a third element (FR) is added into the recipe to increase the composite’s fire stability. Mianowski, T. Lin, Y. Validity of Plant Fiber Length Measurement: A Review of Fiber Length Measurement Based on Kenaf as a Model In Kenaf Properties, Processing and â¦ This may be due to the chemical altering reaction caused by the treatment component. Flight Safety Foundation, Aviation Safety Network on 24th May 2013, E. R. Galea and N. C. Markatos, “A review of mathematical modelling of aircraft cabin fires,”. Besides this, different types of polymers with different characteristics will cause the composites to have different fire behavior. However, the Youngâs modulus of the natural fiber reinforced polymer composites increase with increasing fiber loading. The authors found that the value from the DMA testing is getting lower when the temperature is rising. Omar, A.A.M. There will start a fire from smoke or fume. Postcrash fires are the most severe cases. Currently natural fiber composites have two issues that need to be addressed: resin compatibility and water absorption. Numerous studies have been conducted on kenaf and its hybrid composites. The first cycle is below 100°C, while the second cycle is below 200°C. The survivor escaped by jumping out of the opening where the plane had cracked.

This scenario usually starts when landing [5]. Natural fibres were introduced and increasingly used due to their availability and environmental issues. Thus it is as highly flammable as wood and hence its content portion will affect the flammability of composites. T. Potter, M. Lavado, and C. Pellon, “Methods for characterizing arc fault signatures in aerospace applications, Texas instruments,” 2013, P. J. Herrera-Franco and A. Valadez-González, “Mechanical properties of continuous natural fibre-reinforced polymer composites,”, H. M. Akil, M. F. Omar, A. Lee et al. TGA allowed the determination of the mass of sample lost according to temperature [29]. Fig. Several critical issues and suggestions for future work are discussed, which underscore the roles of material scientists and manufacturing engineers, for the bright future of this new “green” material through value addition to enhance its use. Fire causes substances to rupture. Kenaf (Hibiscus Cannabinus L.) fibres are thermally and alkali treated to enhance the interfacial bond between the fibre-matrix, the mechanical properties of the fibre itself, the fibre-reinforced thermally activated alum sludge ash (AASA) and the nanosilica (NS) blended cementitious composites. In 2010, a tragic postcrash fire occurred and 158 passengers died. Besides this, there are increases of when the kenaf content is getting higher. A. M. Mazuki, H. M. Akil, S. Safiee, Z. Zainudin and K. Abdan2 1 Faculty of Engineering, Department of Mech. Table 2 presents the LOI and heat release rate (HRR) for certain polymers. Higher flame resistances of particleboard made by flame retardant-treated kenaf fibre have been published compared to conventional particleboard [18]. ► Properties of kenaf fiber composite are comparable to conventional fiber composites. Kenaf is also known as Hibiscus cannabinus L. It is an herbaceous annual plant that can be grown under a wide range of weather conditions and produces more than 3 m within 3 months even in moderate ambient conditions [21]. However, different environments will still yield various heights of kenaf plant, such as the cultivar, planting date, photosensitivity, length of growing season, plant populations, and plant maturity. Therefore, composites made up from natural fibre as reinforcement, combined with biodegradable polymer matrices, are the best solution for the environmental issues yet still retain the required strength and properties. A measurement of HRR for a PP matrix with four natural fibres reinforced combinations was conducted by Kozłowski and Władyka-Przybylak [41]. The objective was to compare the mechanical properties of short kenaf bast and core fiber reinforced unsaturated polyester composites with varying fiber weight fraction i.e. Therefore, easy separation of stem can be done either by chemicals or enzymatic retting. This is because of the increase of stiffness of the composite. An Air India Express Boeing 737-800 accidentally crashed when it landing in pre-monsoon rains and then plunged into the jungle [6]. The high moisture adsorption of the natural fibre allowed the absorption of the pigment in the waste water [17]. Review articles are excluded from this waiver policy. 2009: pp.775-888. Dye compounds have been in popular use in many fields, such as textiles, cosmetics, and papers. Besides this, the combustion of biocomposites produces fewer toxic gases compared to conventional composites. The properties of NFPCs varâ¦ 423 fatalities are accounted for 18 major in-flight fire accidents from 1990 to 2010 [4]. BP shows good fire retardant behaviour and this agreed with the research carried out by Abdul Rashid and Chew [56]. The authors declare that there is no conflict of interests regarding the publication of this paper. Nevertheless, Jeencham et al. It is built up of an outer layer of bark and a core. The purpose of this review article is to clarify research and development in improving the mechanical properties of natural fiber reinforced polymer composites along with end applications. Table 5 shows some FR groups and their ways of functioning. Aircraft accidents are often accompanied by fire, but smoke is actually the main threat to passengers. [6] Han, J.S. Table 7 lists the results of the test. Sapuan, Z. Leman, M.R. Davoodi et al. Whilst review articles and even books on the overall properties of natural fiber reinforced composites have been published , , the authors have concluded that a specific review article on the overall characteristics of kenaf fiber reinforced composites, has not yet been published; it is believed that such an article should be of significant value to the composite research community. Boeing Aero, “Flight and cabin crew response to in-flight smoke,” 2013. Fibre crops are not a new product for humans. The combination of APP/Zb fully protected the composite from burning and was classified as V-0 in the vertical burning test. the specific properties are comparable. Abaca fibre as reinforcement in polymer matrices became popular due to applications of its polymer composite in production of exterior components of passenger cars. However, TPU/kenaf composites have lost about 80% of its weight but pure TPU have lost more than 90% of total weight. They have concluded that fiber content of 30 % and 40 % by weight has been proven to provide adequate reinforcement and to increase the strength of the polypropylene composite. Natural fibers, characterized by sustainability, have â¦ Besides this, the authors realised that the amount of kenaf content does affect the value of the experiment.

It can be categorized into four groups (as in Table 1) according to BS476: part 7: 1971. The main temperature peak for pure TPU is around 363°C and is caused by polymerization. Key Words: Natural Fibre, Jute, Basalt, Kenaf, Matrix 1. However, the degradation temperature of the polymer is much higher than natural fibres, for example, LDPE reinforced with kenaf fibre in the experiment. Kenaf/Synthetic and Kevlar®/Cellulosic Fiber-Reinforced Hybrid Composites: A Review Suhad D. Salman,a,c,* Zulkiflle Leman,a Mohamed T. H. Sultan, Mohamad R. Ishak,b,d and Francisco Cardona b This paper reviews the published and ongoing research work on kenaf/synthetic and Kevlar®/cellulosic fiber-reinforced composite materials. Therefore, a precise combination of natural fibre and polymer can enhance the thermal stability. KENAF FIBRES AS REINFORCEMENT FOR POLYMERIC COMPOSITES: A REVIEW I.S. Low visibility caused by two days of continuous rain and the surrounding by hills made rescue work harder. This TG result is shown in Table 6 and it did improve the char residue portion. The composites were pretreated by a silane coupling agent (SCA) in the amount of 1–5%. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. The most potential fire source is electrical. Energy Absorption of Natural Fibre Reinforced Thermoset Polymer Composites Materials for Automotive Crashworthiness: A Review Mohamed Alkateb, S.M. Copyright © 2011 Elsevier Ltd. All rights reserved. They usually come in the form of a powder and contain 5 to 10% of it inside the sample. Kenaf fiber is extracted from bast fiber of kenaf plants. Besides this, each fire analysis can detect different kinds of fire properties. Therefore understanding the flammability of natural fibre based polymer composites could modify its fire behaviour thus allowing passengers more time to escape from an incident. In addition, it presents summary of various surface treatments applied to natural fibers and their effect on NFPCs properties. The study shows that the flexural properties of Long bast fibre types are used to make high- grade pulps for the pulp and paper industry, composite boards, or textiles. Understanding its flammability factors and improving them will help to delay passenger panic and hence extend the escape time. Ishak, Mohammad Jawaid Energy absorption capacity of composite materials is important in order to develop safety measurements for human beings in a car accident. The results show that the storage modulus of the sample was decreased after the immersion process. ► Kenaf fiber is unique and potentially reliable. Energy absorption, fiber type, matrix type, fiber â¦ DSC measurement is also being conducted in research. These engineered fibres are being produced with uniform properties in every single fibre in terms of dimensions and mechanical properties [10].

Chemical compounds are the most commonly used FR fillers. The highest growing rate may be up to 10 cm/day. The plane was broken into two immediately and burst into flames. The bark contributes 30–40% of the dry weight for the stem and shows a dense structure. On the other hand, Suharty et al. have determined that nitrogen application at 90 kgN/ha has significant effect for plant growing. Thus, the flammability of a natural fibre PMC requires much research from many aspects, and kenaf fibre can be said to be one of the most highly recommended natural fibres in the world.

This compatible agent result can be explained by looking at the morphological observation in Figure 2. Among the many different types of natural resources, kenaf plants have been extensively exploited over the past few years. The candidates used in the research are completely biodegradable poly(3-hyroxybutyrate-co-3-ohydroxyvalerate) (PHBV), random copolyester of poly(butylenes adipate-co-terephthalate) (PBAT), and low-density polyethylene (LDPE). [16] used kenaf fiber neutral polypropylene reinforced composites. Mazuki et al. a Corresponding author: fahmyjusoh@gmail.com NATURAL FIBER REINFORCED COMPOSITES: A REVIEW ON POTENTIAL FOR CORRUGATED CORE OF SANDWICH STRUCTURES A.F. Yet they have some probability of becoming uncontrolled fires. Figure 1 shows the percentage of composite materials used in an aircraft; it demonstrates increasingly higher percentages of structural weight being replaced with lighter yet more combustible composites material. In this paper, fire flammability is the main concern for natural fibre reinforced polymer (NFRP) composites especially kenaf fibre. 2 showed the parts of kenaf stem (core, bast and innerbast). [43] investigated the viscoelastic behavior for Kenaf/Polylactic Acid (PLA) composites with a DMA test. Therefore, we can announce that silica is the most compatible synergistic agent rather than Mg(OH)2 and Zb. estructure On the other hand, animal bedding, sorbents, and horticultural mixes use short core fibres [23]. In-flight fires are normally detected at the beginning of the fire and can be successfully extinguished. A. M. Mazuki, S. Safiee, Z. Heat emerges as a result of the chemical reactions of the combustion process. The percentage of fibre content is directly proportional to its value until 70 wt% of fibre. This phenomenon leads to a reduction of the product’s strength. [33]. It has the lowest 5% weight lost temperature and char residue. Expelling the wastewater containing dye compounds into clean water will dissolve the oxygen content in the water and prohibit sunrays passing through the water as well. Kenaf fiber is usually reinforced with synthetic based polymer resin such as polypropylene. ► Kenaf fiber is extracted from bast fiber of kenaf plants. A fire ignition test was carried out in the laboratory by Izran et al. This is a surface modification to link between the particles [44]. [53] haves used Mg(OH)2 and Zb as synergists with ammonium polyphosphate [APP] in a sisal/PP composite. Besides this, kenaf fibre is being used to produce paper to avoid the deforestation problem. LOI is the elementary density of oxygen in a percentage that supports the combustion of a polymer. Lastly, to inspect a fire, several methods were used: Thermo Gravimetric Analysis (TGA), Different Scanning Calorimetric (DSC), and Dynamic Mechanical Analysis (DMA). Yet the mechanical properties were nearly halved for all properties, such as compressive strength, wear ability, and tensile strength. Demir et al. From the results (Table 3), glass transition temperature, , and melting temperature, , were not influenced by the appearance of the silane coupling agent. Hybrid composites of wood flour/kenaf fiber and polypropylene were prepared at a fixed fiber to plastic ratio of 40 : 60 and variable ratios of the two reinforcements namely 40 â¦ Nevertheless, these treatments do enhance its tensile strength, young’s modulus, and elongation ability. Fire behaviour properties are significant factors for natural fibre based polymer composites in terms of safety. Different kenaf fibre loadings samples were fabricated by compression moulding from 20% to 50%. When the fire is somehow ignited, work has to be done to reduce the fire propagation rate. ► Kenaf fiber composite can be produced using conventional fiber composite manufacturing. In the outcome, fibre contents were inversely proportional to the thermal stability. Maintenance is very important to ensure a safe environment on an aircraft. [17] investigated the mechanical properties of kenaf fiber reinforced in poly lactic acid composite. Russo et al. Natural fibre is a well-known reinforcement fibre in polymer-matrix Composites (PMC) lately. The reason for performing the first cycle is to eliminate the moisture content and thermal stress in the composites because the result is highly affected by water in sample [36]. A few types of fire retardant filler added into the sample tend to get better results, such as monoammonium phosphate (MAP), diammonium phosphate (DAP), and a mixture of boric acid, guanylurea phosphate, and phosphoric acid (BP).

Everything in the fire will eventually become charcoal, gases, and heat. analyzed the kenaf fiber reinforced poly-lactic acid for its mechanical properties. ► Kenaf fiber composite have a bright future due to its renewability and eco-friendly. As a conclusion, neither acidic nor alkaline conditions make composites work better than in normal conditions. Components like polymers and natural fibres are natural fire conductors. These minerals also help to increase cumulative weed weight, crop height, stem diameter, and fibre yield [25]. John et al. SCA will undergo hydrolysis and condensation reactions to form silanol groups. Shinji Ochi et al. Optimum fiber content 20%. All results show that the kenaf natural fibre shifts the onset thermal degradation temperature a little bit to the left for all matrices with the same fibre content. The core shows an isotropic and almost amorphous pattern, while the bark has an oriented high crystalline fibre pattern [22]. Researchers have noticed that some of the conventional products do not currently fulfill these requirements. MAPP creates an adhesive bridge for a better interface between fibres and matrixes [46]. Eliminating the ignition of a fire is the first priority, but the least we can do is to extend its ignition time. [35] conducted an experiment regarding the effect of kenaf fibre content on composites when in a fire. It is possible to gather information such as Young’s modulus/storage modulus, , loss of modulus, and mechanical loss factor, and tan, as a function of deformation [30]. The increase of crystalline caused by the kenaf fibre was stimulated into heterogeneous crystallization. From Figure 2(b), silica agents reduce the size of big APP particles and thus maintain the structure of composites. Aircraft cabin fires are generally grouped in ramp fires, in-flight fires, or postcrash fires. Chaturvedi et al. As increases occurred in the portion of APP, some big cell sizes formed irregular shape and this disturbed the original formation of wood/PP particles. [54] took the challenge to integrate it with a silica synergistic agent. The tensile strength and Youngâs modulus of composites reinforced with The results also showed that the optimum fiber Kenaf fiber has been widely used as reinforcement in composites over the past few years which is a most attractive alternative due to its rapid growth at different climatic conditions and ensuring low cost; kenaf fiber has gained some attention to replacing the glass fiber â¦ & Manufacturing Engineering, University Putra Malaysia 2 Laboratory of Biocomposite Technology, Institute of Tropical Forestry and Forest Products Universiti Putra Malaysia, Malaysia These composites bring us about high mechanical and thermal properties which are the main characteristic required in various applications from aerospace to sport uses. Environmental awareness and trends to develop sustainable resources have directed much research attention towards kenaf fibre as an alternative reinforcement in composite manufacturing. Only eight passengers have saved themselves in this incident. At the same time, storage modulus, , and loss of modulus, , are increasing as well through DMA. Rejab1, J.P Siregar1, D. Bachtiar1 1Faculty of Mechanical Engineering, Universiti Malaysia Pahang 26600 Pekan, Pahang, Malaysia Abstract. thermogravimetric analysis (TGA), different scanning calorimetric (DSC), and dynamic mechanical analysis (DMA) are the three most famous methods used to investigate the fire behaviour of composites. The development of high-performance engineering products made from natural resources is increasing worldwide, due to renewable and environmental issues. Sapuan , E.S. Mazuki, S. Saï¬ee, Z.A.M. Researchers Kuchinda et al. One is that kenaf absorbs the nitrogen and phosphorus that are present in the soil. By continuing you agree to the use of cookies. Therefore, the escaping timing can be extended to more than an hour. C. H. Lee, Mohd Sapuan Salit, M. R. Hassan, "A Review of the Flammability Factors of Kenaf and Allied Fibre Reinforced Polymer Composites", Advances in Materials Science and Engineering, vol. Natural fibre has fast growing and abundance properties which make it available at very low cost. [13] replaced a car bumper beam with a hybrid kenaf/glass reinforced epoxy composite to reduce the environmental issue, yet retain the required strength. A. Rashid, F. Abood, and S. Rahim, “Optimising treatment system for kenaf (, A. M. Abdul Rashid and L. T. Chew, “Fire retardant treated chipboards,” in, United States Government General Accountability Office, “Aviations safety: status of FAA’s actions to oversee the safety of composite airplanes,”, P. Joseph and J. Ebdon, “Recent developments in flame-retarding thermoplastics and thermosets,” in. Therefore manufacturers are keen to find lighter insulation materials. However, both of the heat of fusion () and the degree of crystalline () had increased about 4 J/g and 4%, respectively. This means that the kenaf plant is environmentally friendly not only in terms of its biodegradability, but in the fact that it also produces a lot of oxygen as well as reducing carbon dioxide. The ignition time widely depends on the heat intensity, the oxygen density, and the air flow in that particular area. 2. The results showed that increases by adding kenaf content at all temperatures. BP is able to extend its ignition period more than untreated board by doubling the time to 2 minutes. Ishak et al. J. Shaw, “A review of smoke and potential in-flight fire events in 1999,” Tech. As a conclusion of both papers, Mg(OH)2 gives the most thermal stability, Zb exhibits the most char residue, and APP reduces the burning rate the most. The matrix of the composite will melt away, and the fibre is under thermal decomposition as well. Kenaf fiber composite have a bright future due to its renewability and eco-friendly. Most studies were conducted on kenaf/glass hybrid composites compared to other kenaf/synthetic hybrid composites. However, they are being abandoned because of the environmental and health issues created. Introduction: Because of its optimized properties such as high strength and less weight, more precise strength etc., natural fiber reinforced composites play an important role in advanced technology. The rate of fire spread is tested by fire propagation test [27]. This paper reviews the published and ongoing research work on kenaf/synthetic and Kevlar®/cellulosic fiber-reinforced composite materials. By having TGA, it was found that the fire behaviour of composites tends towards fibre fire behavior when its proportion increases in composites. Although the presence of the natural fibre brought an earlier ignition, the heat released by natural fibre composites was noticeably reduced by more than 50% of the pure PP matrix. J. E. McIntyre, The Chemistry of Fibres, 6, Edward Arnold, 2009. The first peak of mass drop for kenaf fibre is hemicelluloses degradation and this begins at around 200°C [34]. For kenaf fibre there is long lists of research projects which have been done regarding its behaviour, and properties and modification made to it.
