Abstract

Nowadays, natural fibres have received considerable attention from researchers and have become an important issue for alternative solutions in replacing the synthetic fibre to solving ecological and environmental problems. Among the many types of natural fibre available, pineapple leaf fibre (PALF) has been selected as the natural fibre used in this study because it has a better mechanical properties and it also has a low production cost. The PALF from the Josapines type has high cellulose content and has excellent mechanical properties. In this study the PALF of the Josapines type will be used as reinforced material while cornstarch is a binder. In this study, the effect of the content of PALF and the fibre length of the composition of PALF / TPCS will be analyzed. Five different PALF compositions are set at 20, 30, 40, 50, and 60 wt.% while the length of the fibres is 2mm and 10mm. The composite samples were fabricated by using compression moulding techniques with PALF randomized orientations. The sample will undergo three different tests, which are mechanical testing, physical testing and environmental testing. The highest result of mechanical testing in term of length is 10mm fibre length. For the tensile strength at 40% fibre loading shows the highest result which is 10.51MPa while for flexural testing the highest results at the 50% fibre loading 15.55MPa. Lastly, for impact testing higher result in the 20% fibre loading at 6.58MPa.
