Various Lignocellulosics Fibre Reinforced Polyester Composites: The Study on Mechanical, Physical and Biological Properties

摘要

Non-woven lignocellulosic fibres (oil palm empty fruit bunches (EFB), bamboo fibres and pineapple leaf fibres) reinforced thermoset composites were fabricated at different fibre weight fractions, i.e. 10, 20, 30, 40 and 50%. The polyester resin (unsaturated) and MEKP as catalyst were used. The mechanical, physical and biological properties of composites were analyzed with and without fibre treatments (control untreated, acetylation, prepreg ABS and silane) in composites. In general, as increased the weight fraction in matrix, the composite properties increased. The mechanical properties followed the order: bamboo (highest) > pineapple > EFB (lowest). Fibres treatments with ABS exhibited the highest mechanical strength and lowest water absorption of composites followed by acetic anhydride, silane and untreated fibres composites. However, the value was still lower as compared to the glass fibre composites.
