Abstract

The purpose of this research is to look into the mechanical properties and failure analysis of Bemban fibre and thermoplastic polyamide turned to composite. The main objectives for this of this this research is to study the mechanical properties of Bemban mix with thermoplastic and effect of water absortion, to investigate the effects of various mixture combinations on the mechanical characteristics of thermoplastics with Bemban and the effect of water absorption and to investigate the failure process of Bemban reinforced thermoplastic. The main material used in this project is Bemban fiber and thermoplastic. Bemban fiber is processed from raw material to get the fibre by using a manual extraction method and grinding the fiber in order to get perfect short size fiber. Mixture ratio of Bemban and polyamide is 1:10, 1:5 and 1:1 by using hot press machine by using moulded with size of 250 mm x 250 mm x 3 mm. After the composites is ready to be cut, two composite mixture samples will undergo a tensile test to get the result for mechanical properties based on ASTM test standards. One of the samples will undergo a water absorption method. It is expected that tensile properties Bemban fibre will increase with increase of fibre fraction. In this study, ratio with 1:1 shows the best plotted line graph and help matrix in strengthen the composite. In this study, matrix itself is already strong enough even without the help of fiber.
