Unformatted text preview: coupling agent was ad ded into the composite formulations and compared with composite system without MAPE. Tensile strength, elongation at break and impact resistance were reduced while tensile modulus was increased with increasing filler loading. The percentage of water uptake also increased with increasing fillers loading. Incorporating of MAPE into composites increased mechanical properties and reduced the percentage of water uptake. Composites with kenaf core fillers showed lower mechanical properties and absorbed more water as compared to composite with the commonly used natural filler, wood flour. 229 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia POLY-P3 THE MELT FLOW BEHAVIOUR LOW DENSITY POLYETHYLENE (LDPE)/ PALM KERNEL SHELLS (PKS) COMPOSITES Lim Bee Ying, Salmah Husseinsyah and Teh Pei Leng School of Materials Engineering, Universiti Malaysia Perlis, Taman Muhibah, 02600 Jejawi, Perlis, Malaysia E-mail: [email protected] The melt flow behavior of Low Density Polyethylene (LDPE)/palm kernel shell composites was studied. The composites were prepared and the melt flow indices were determined under temperature of 190, 200 and 210 °C using melt flow indexer. In this study, the effect of temperature and filler loading on the melt behavior of composites were determined. The apparent viscosity of the composite was found to exhibit linear relationship with reciprocal of the temperature. The increase of filler loading led to the decreasing of melt flow index as the viscosity of the composites increased. POLY-P4 COCONUT SHELL POWDER FILLED POLYESTER COMPOSITES: A STUDY ON THE MECHANICAL PROPERTIES Marliza [email protected], Salmah Husseinsyah and Teh Pei Ling Pusat Pengajian Kejuruteraan Bahan, Universiti Malaysia Perlis, Taman Muhibah, 02600 Jejawi, Perlis, Malaysia E-mail: [email protected] Natural lignocellulosics have an outstanding potential as reinforcement in thermosets. Coconut shell (CS) is one of natural lignocellulosic material. The tensile and flexural propertie...
