Abstract

Nowadays, the growing of the science and technology is the main problem to the environmental and become very serious all over the world. Researchers are working together to produce the environment-friendly material or also known as a green material in order to solve this critical problem. Researchers have focused the usage of natural fibre to replace synthetic fibre. Natural fibre have a lot of advantages compare with synthetic fibre such as low cost, eco-friendly product and can reduce waste of pineapple leaf. In this research, the objective is to investigate the effect of surface treatment PALF to the vinyl ester reinforcement in terms of mechanical, physical and morphological properties. The parameter use in this research is 5wt% of the fibre loading for untreated and treated of PALF. The chemical treatment use is alkaline treatment which is 6% of NaOH. The sample will be characterized in term of their physical, mechanical and morphological properties. Based on the physical properties, the density of the treated composites was higher due to increase the amount of the fibre in the composites, the treated composites also show good result for moisture content and water absorption. For the mechanical properties, treated composites showed an improvement for tensile and flexural strength. This is because alkaline treatment on the fibre improve the interfacial bonding between fibre and polymer. For morphological analysis, treated composites also has good surface structure because there is no gap between fibre and matrix and less fibre pull-out compared with the untreated composites sample. As the conclusion, alkali treatment on the natural fibre improve the interfacial bonding between fibre and polymer.
