Figure 25.12. The pulps were then refined to 300 mL CSF. Innovation Planets are showcase areas where OEMs and suppliers can discover the best applications for composites in their market. Figure 25.5. Awal et al. Therefore, some modification performed on fibers such as chemical treatment was carried out. 25.12. The other manufacturing factors such as mold wall heating, closing rate of two matched plates of the plates, and de-molding time also affect the production process. Figure 18.9. The bast fiber can be compared to softwood, which is a high quality fiber typically used for commercial paper production. EFB and kenaf core fibers used for the experiments were obtained from Sabutek Sdn. Figure 5.6. During the CC tests, controlled constant heat flux (50 kW/m2) was maintained to observe the combustion process of the composites. Stronger virgin fiber may be needed as a replacement for hardwood, which is typically mixed with secondary fiber, in corrugating medium. Other kenaf uses include animal forage, animal litter, a fiberglass substitute in molded plastic, a cellulose fiber … 25.6). Davoodi et al. (2004) has revealed the two main attracting reasons of kenaf fiber. The corresponding values at 6-m depths were 33 kPa and 32 kPa, respectively. On the other hand, pure PP starts to drip at an early stage of ignition under UL-94 V standard tests (Figure 4.18(a)), which leads to an increase in pool fire growth. Comparison of tensile strength of kenaf for all patterns. Hao, ... R.M. Highlight your know-how on a dedicated zone through the JEC events. Cultivation and harvesting trials started in 2000, followed by trials on high-protein kenaf forage for dairy cattle. In this work, thermoplastic sago starch (TPSS)/kenaf core fiber (KF) biocomposites were prepared at different fiber loadings (0 to 35 wt.%), and the effects of fiber loading were analyzed by mechanical tests, TGA, FTIR, SEM, and water absorption behavior. The JEC conference programs aim to educate and provide the latest information, trends and experience feedbacks to professionals willing to improve their knowledge and seize the consequent networking opportunities. This study investigated the use of kenaf core fiber as a feedstock for enzyme-enhanced fermentation. Business meetings are a component of every JEC Group event (JEC World, JEC Asia, JEC Forum in the US) that enables participants to meet highly qualified business contacts. The study of the kenaf core fiber – polymer composites was done by preparing a kenaf/polymer composite using polypropylene (PP) polymer matrix and Scona TPPP 9012 GA as coupling agent with Nigerian grown Kenaf natural fiber through hot pressing. Electrical Breakdown of Kenaf Core Fiber / Lignin / Polypropylene Biocomposite Harmaen Ahmad Sa an 1, * , Mohd Aizam Talib 2 , Seng Hua Lee 1, * , Paridah Md Tahir 1 , When evaluating fire-retardant properties of composite materials, sustained heat of combustion provides important information about the materials’ tendency to extinguish or to spread the fire. [10] compared Kenaf bast fiber with kenaf core fiber, bast fiber shows better mechanical properties than core fiber. The peak friction angles of sand backfill only, as well as kenaf with sand backfill, were 35.63° and 27.66°, respectively, with the corresponding cohesion values of 11.33 and 9.26 kPa, as shown in Fig. 25.1. The controlling parameters in compression molding method to develop superior and desired properties of the composite are shown in Fig. Yields of kenaf range from 8-12 metric tons of dry stem per hectare. The extensometers were installed at all the layers (6 layers) of reinforcements. The results had indicated the mechanical properties of the concrete composite were comparable to plain concrete specimen. It is processed into poultry house bedding, oil-absorbent mats and packing materials. Comparison of observed and predicted subsurface settlements at 3 m depth. However, the poor mechanical properties of the renewable materials have limited the idea of using natural fiber. The bast kenaf fiber has better strength properties than core fiber; hence it is more suitable for high strength applications. The main goal of our initial work was to investigate the fire-retardant effectiveness of PP/kenaf natural fiber composites with and without APP-based IFR system. Malaysia has now become a regular participant at the JEC Composites Paris and Asia. Many types of paper are made from a blend of hard and softwoods, and kenaf provides a natural blend of such a fiber mixture. The entire composites business filtered by sector. (1998), the incorporation of 20 pph kenaf fiber significantly increased the HDT of annealed PLA from 99.7°C to 128°C. Kenaf bast were hermetically digested into single fiber using a 5% sodium hydroxide solution for one hour at four different temperatures (80°C, 110°C, 130°C, and 160°C). An interesting study was also carried out by introducing fique mats in a low-density polyethylene matrix with aluminium films, obtained from the recycling of the nonpaper part of Tetra Pak. The Prime Minister Dato’ Seri Najib Tun Razak has already launched a Green Technology programme. Kenaf is cultivated for its fibre in India, Bangladesh, United States of America, Indonesia, Malaysia, South Africa, Viet Nam, Thailand, parts of Africa, and to a small extent in southeast Europe.The stems produce two types of fibre: a coarser fibre in the outer layer (), and a finer fibre in the core… Kenaf fibres of different lengths were also introduced as the reinforcement of a soy-based matrix in an extruded, then compression or injection moulded, laminate. The boron is capable to provide protection to postpone the heat transfer (Horrocks and Price, 2001). The fibres (Fig. The trials showed that 6-8 week-old kenaf contains approximately 18% crude protein (Fig. 7.2: Kenaf powders (in the specific field of application of wood powders). Products range from biocomposites, paper, textiles, cattle feed and absorbing agents. Six layers of woven kenaf with 4 mm opening size were utilized as reinforcement with vertical spacing of 0.5 m (Fig. Three types of composites have been fabricated, which are the pure fiberglass, hybrid glass fiber/kenaf fiber, and hybrid glass fiber/jute fiber. Paramount is that kenaf is a renewable and sustainable alternative with a short gestation period of only four months. In this case, 1 hectare produces 5~7 tons of high-quality fiber, while the yield of ethanol extracted from the core is 4,500~6,000 liters. Table 4.5. The triple of photosynthesis rate of kenaf (23.4 mg CO2/dm2/h) compared to conventional tress (of 8.7 mg CO2/dm2/h) under 1000 µm mol/cm2/s helped to reduce the carbon dioxide while producing oxygen (Lam and Liyama, 2000). Figure 7.5. On the other hand, Huda et al. Kuchinda et al. 1991). Figure 5.5. Table 4.6. Kenaf fiber is one of the famous natural fibers used as a reinforcement in polymer matrix composites (PMC). The interface coefficient from the direct shear test was found to be 0.81, which can be applied to use as interaction behavior of kenaf reinforcement (Chaiyaput et al., 2014). To date, the Government has spent RM50 million to develop kenaf through research and development in upstream and downstream areas. The degree of compaction and the moisture contents were checked regularly at several points with sand cone tests. Kenaf is cultivated for its fiber in India, Bangladesh, U.S., Indonesia, Malaysia, South Africa, Viet Nam, Thailand, and parts of Africa, and to a small extent in southeast Europe.
