The following preliminary research has investigated the use of Kenaf, Hibiscus cannabinus, as a possible glass replacement in fiber reinforced composites. Eliminating the ignition of a fire is the first priority, but the least we can do is to extend its ignition time. In addition, it presents summary of various surface treatments applied to natural fibers and their effect on NFPCs properties. Long bast fibre types are used to make high- grade pulps for the pulp and paper industry, composite boards, or textiles. Kenaf fiber is unique and potentially reliable. Maintenance is very important to ensure a safe environment on an aircraft. The core is a wood-like structure that makes up the remaining 60–70% of the weight. Heat emerges as a result of the chemical reactions of the combustion process. In 2010, a tragic postcrash fire occurred and 158 passengers died. 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. The tensile strength and Young’s modulus of composites reinforced with Natural fibers are getting attention from researchers and academician to utilize in polymer composites due to their ecofriendly nature and sustainability. Yet the value becomes higher by increasing the coupling agent amount throughout the temperature. For kenaf fibre there is long lists of research projects which have been done regarding its behaviour, and properties and modification made to it. A study focusing on kenaf fibre reinforced thermoplastic polyurethane (TPU) composites showed that the impact strength values of the materials prepared with the smallest size of kenaf fibre (<125 µm), medium size of kenaf fibre (125–300 µm) and the largest size of kenaf fibre (300–425 µm) were 2.1, 2.76 and 2.97 kJ/m 2, respectively . Sign up here as a reviewer to help fast-track new submissions. Fortunately, they have a very low probability of becoming uncontrolled in-flight fires. From the results (Table 3), glass transition temperature, , and melting temperature, , were not influenced by the appearance of the silane coupling agent. [53] haves used Mg(OH)2 and Zb as synergists with ammonium polyphosphate [APP] in a sisal/PP composite. MAPP creates an adhesive bridge for a better interface between fibres and matrixes [46]. This is because of the increase of stiffness of the composite. This review paper deals with the previous and current works published on the kenaf fiber composites. Sapuan , E.S. It is believed that more studies will focus on this area in the future. Three samples with 70% of kenaf fibre content were immersed in pH 5.5, pH 7, and pH 8.9, which represent acidic, neutral, and alkaline solutions, respectively, for 24 hours. Currently natural fiber composites have two issues that need to be addressed: resin compatibility and water absorption. Rep. Doc 185, Society of Automotive Engineers, Washington, DC, USA, 2000. Only eight passengers have saved themselves in this incident. The kenaf bast fiber is known to have the potential as a reinforcing fiber in In Julkapli and Akil’s [29] research, they performed a DSC analysis twice on kenaf-filled chitosan composites. The study shows that the flexural properties of One is that kenaf absorbs the nitrogen and phosphorus that are present in the soil. Fire causes substances to rupture. ► Kenaf fiber is extracted from bast fiber of kenaf plants. the specific properties are comparable. Chemical compounds are the most commonly used FR fillers. The values were reduced to 4 GPa, 3.8 GPa, and 3 GPa for pH 7, pH 5.5, and pH 8.9 separately at their (172°C). The results also showed that the optimum fiber have determined that nitrogen application at 90 kgN/ha has significant effect for plant growing. Omar, A.A.M. 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. Besides this, each fire analysis can detect different kinds of fire properties. Fire propagation capabilities depend on the total heat liberated and the fire spread for a fuel [27, 28]. Therefore a third element (FR) is added into the recipe to increase the composite’s fire stability. The other reason is that kenaf transforms carbon dioxide to oxygen at a significantly higher rate. The combustibility or lowered flame retardancy hampered the diverse applications of kenaf fibers reinforced polymer composites, as it affects the mechanical strength and stiffness of composites during fire. Table 2 presents the LOI and heat release rate (HRR) for certain polymers. John et al. LOI is the elementary density of oxygen in a percentage that supports the combustion of a polymer. The bark contributes 30–40% of the dry weight for the stem and shows a dense structure. Kenaf is the most common natural fiber used as reinforcement in polymer matrix composites (PMC). Natural fibre has fast growing and abundance properties which make it available at very low cost. As a result, MAPP modifications are able to reduce the LOI values more compared to SCA. The thermal decomposition of a natural fibre always started by low temperature of hemicelluloses decomposition and is followed by a sudden drop of mass caused by the pyrolysis of cellulosic. Dye compounds have been in popular use in many fields, such as textiles, cosmetics, and papers. Environmental awareness and trends to develop sustainable resources have directed much research attention towards kenaf fibre as an alternative reinforcement in composite manufacturing. This is because the thermal behaviour of kenaf fibre takes priority as increasing its content. Components like polymers and natural fibres are natural fire conductors. The results showed that increases by adding kenaf content at all temperatures. POLIMERY. M. M. Davoodi, S. M. Sapuan, D. Ahmad, A. Ali, A. Khalina, and M.

They usually come in the form of a powder and contain 5 to 10% of it inside the sample. The rate of fire spread is tested by fire propagation test [27]. Kenaf fibre is the most well-known natural fibre option studied by researchers. The main temperature peak for pure TPU is around 363°C and is caused by polymerization. morphological analysis of kenaf fiber reinforced polymer composites has been discussed. This compatible agent result can be explained by looking at the morphological observation in Figure 2. It has the lowest 5% weight lost temperature and char residue. It is not discussed in this review due to its newness which means there is a lack of research information on the natural fibre reinforced in nanocomposites. Natural Fiber Reinforced Composites (NFPCs) Natural ber polymer composites (NFPC) are a composite material consisting of a polymer matrix embedded with high-strength natural bers, like jute, oil palm, sisal, kenaf, and ax []. 2. Zainudin and K. Abdan2 1 Faculty of Engineering, Department of Mech. The composites were pretreated by a silane coupling agent (SCA) in the amount of 1–5%. A. M. Ishak, and A. These engineered fibres are being produced with uniform properties in every single fibre in terms of dimensions and mechanical properties [10]. TheGuardianNews, “India Jet Crash Leaves More Than 150 Dead in Mangalore,” 2013. As a conclusion, neither acidic nor alkaline conditions make composites work better than in normal conditions. There will start a fire from smoke or fume. [47] have revealed TGA outcomes that are totally different. Abaca fibre as reinforcement in polymer matrices became popular due to applications of its polymer composite in production of exterior components of passenger cars. [43] investigated the viscoelastic behavior for Kenaf/Polylactic Acid (PLA) composites with a DMA test. Rejab1, J.P Siregar1, D. Bachtiar1 1Faculty of Mechanical Engineering, Universiti Malaysia Pahang 26600 Pekan, Pahang, Malaysia Abstract. BP is able to extend its ignition period more than untreated board by doubling the time to 2 minutes. BP shows good fire retardant behaviour and this agreed with the research carried out by Abdul Rashid and Chew [56]. ScienceDirect ® is a registered trademark of Elsevier B.V.

Summerscales, N. P. J. Dissanayake, A. S. Virk, and W. Hall, “A review of bast fibres and their composites. Properties of kenaf fiber composite are comparable to conventional fiber composites. The first peak of mass drop for kenaf fibre is hemicelluloses degradation and this begins at around 200°C [34]. Demir et al. This TG result is shown in Table 6 and it did improve the char residue portion. The photosynthesis rate of kenaf is much higher than the photosynthesis rate of conventional trees [21]. 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]. It can be categorized into four groups (as in Table 1) according to BS476: part 7: 1971. 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. The kenaf fiber polypropylene composites have a higher At the same time, increasing the kenaf quantity led to a drop of value. The rate of fire propagation determines the flame classification of the materials that spread across the surface. Natural fibres namely sisal, jute, kenaf, hemp, abaca and banana are mainly used in … The first mass losing at a low temperature in all sample are due to expelling the moisture. Even humans in the Stone Age combined some short length fibres and twisted them together as cords and yarns [12]. Thus it is as highly flammable as wood and hence its content portion will affect the flammability of composites. Mazuki et al. 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]. Nevertheless, Jeencham et al. Besides this, DSC analysis concluded that adding a coupling agent will have no effect on both glass transition temperature, , and melting temperature, . Review articles are excluded from this waiver policy. J. E. McIntyre, The Chemistry of Fibres, 6, Edward Arnold, 2009. [2] have shown that more than 41% of fatalities are caused by fire and smoke in an aircraft crash. Review of kenaf fiber reinforced polymer composites.
