Effect of Coir Fiber Length and Content on Mechanical Properties of Unsaturated Polyester Composites

Abstract

This research was carried out to study the effect of weight fraction of coconut coir fiber treated withNaOH (0, 5, 10, 15 and 20%) and fiber length (1, 3 and 5 cm) on the mechanical properties of the unsaturated polyester composites. Some mechanical tests were carried out like: tensile strength, impact strength and flexural strength. The results show that all values of these properties were found to increase with the increasing fiber loading and fiber length.
