Abstract

In recent years natural fibre appears to be outstanding material which comes as the viable and abundant substitute for the expensive and nonrenewable synthetic fibre. Natural fibre like sisal, banana, jute, oil palm, kenaf and pineapple leaf have been used as reinforcement in thermoplastic for application in furniture, low cost housing, and civil structures. This research is focus on natural fibre reinforced composite that have received increasing attention in variety industry. Pineapple leaf fibre is one of natural fibre that has also good potential as reinforcement in thermoplastic composites. The treated pineapple leaf fibre reinforced PLA have been used in the fabrication process of the biocomposites by using the compression molding via hot press machine to form a thin film. Following this, a series of mechanical series which are tensile (ASTM D3039), flexural (ASTM D790) and impact (ASTM D6110) were conducted. Scanning electron microscope (SEM) analysis was done to scrutinize the topology and morphology of the PALF/PLA composite. Overall, the experimental work suggest than alkaline treatment PALF fibre with continuous long fibre reinforced PLA biocomposites exhibit superior mechanical properties in comparison to that of the plain polymer and data from literature review when subjected to tensile , flexural and impact test,with wt 30% of fibre loading.
