In this study, the physical properties of thermoplastic composites manufactured from linear medium density polyethylene (LMDPE), rice husk (RH) and maleic anhydride polyethylene (MAPE) were evaluated. Composites were manufactured with RH loadings of 15 wt%, 30 wt% and 50 wt% with 1 wt% of MAPE to investigate the effect of RH loading on the physical properties (water absorption and thickness swelling) of the composites. The results show that the water absorption and the corresponding thickness swelling increased with an increase in RH loading. Further manufacturing was carried out with 50 wt% of RH and 1wt%, 3.5 wt% and 6 wt% of MAPE to evaluate the effects of interfacial modification on the physical properties of the composites. The results show that the composites with 3.5 wt% of MAPE had least water absorption and the corresponding thickness swelling, whereas the composites having 1 wt% of MAPE had maximum water absorption and the thickness swelling. It can be concluded from these experiments that fibre loading as well as interfacial modification play a significant role in determining the physical properties of the composites.

Rice Husk Flour

Different properties (tensile strength, elongation, modulus, impact strength) of rice husk (RH) reinforced polypropylene (PP) coupled by Maleic-Anhydride grafted Polypropylene (MAgPP) have been investigated. MAgPP is an effective coupling agent, not only in cellulosic-fibre filled polyolefine composites, but in rice husk flour filled polypropylene composite systems as well. It gives a utilizable construction polymer matrix composite (PMC) material even at a 40 wt.% RH filling degree. The strength and modulus increases by adding the rice husk but the elongation decreases in a non-monotonic way. Micrographs shows weak coupling in between RH and PP without MAgPP.

Rice husk is one types of sustainable and economical agricultural wastes that could produce particleboard as the substitute for solid wood. The problems that encourage this research are due to the increasing of deforestation and the increment demand for solid wood in various industries. Malaysia produces a significant amount of agricultural biomass waste every year. It is noteworthy to mention that agricultural wastes can be fully used in an environmentally friendly way. This study aims to evaluate the properties of particleboard made from rice husk at different fibre loading and mixture. Different formulated composition of rice husk and pine wood shaving was prepared for the production of particleboard by hot pressing at temperature 160 °C for 6 min using Urea-Formaldehyde (UF) resin with additional of ammonium chloride (NH4Cl) as a hardener. The results showed the density values and moisture content of particleboards ranging from 0.547 to 0.660 g/cm3 and 8.072 to 8.929 %, respectively. The thickness swelling and water absorption were increased as the increment of soaking time. Besides, the colour of the rice husk-pine particleboards has no significant difference and changes except for particleboard made from 100% rice husk. While the more proportion of pine wood shaving has the better compaction of particleboards, and the addition of grinded rice husk also make the particleboards have fewer voids. This study is expected to reduce deforestation activities and to maximize the usage of agricultural wastes.
