Tensile and Impact Strength of Coir Fibre Reinforced Polypropylene Composites: Effect of Different Temperature Conditions

摘要

This study focuses on tensile properties and impact strength of coir fibre reinforced polypropylene composites under influences of fibre loading and various temperatures conditions. All samples were fabricated by using hot-press technique. Tensile and izod impact samples were prepared in accordance to the standard specifications as closely as possible. Three different ratios of fibre with matrix which were 10%, 20% and 30% were studied. The results revealed that 20% volume fraction of coir fibre demonstrated optimum tensile and impact properties. Significance reduction of impact strength under low temperature condition had been shown for all composites due to the brittleness of both fibre and matrix.
