Normalization of impact energy by different layer arrangement for kenaf-glass hybrid composite laminates

Abstract

An increase of interest to mesh up two or more fillers in the matrix is increasing. The main objective is to improve the performance of a single filler reinforced matrix with other fillers that have higher strength as compared to the initial fibre. Thus, in this study, kenaf fibre plies have been hybridised with woven glass fibre mats in order to improve its post impact tensile properties. These hybrid composite materials were fabricated by hand lay-up and cold press techniques. Two different systems were fabricated based on specific fibre layer arrangements of kenaf-glass fibre reinforced polymer (KGFRP) hybrid composites. The results revealed that the woven glass fibre at the outer layer arrangement produced better strength than having kenaf fibre at the outer layer as shown in Normalized Stress curve. This arrangement helps to sustain more impact, as a consequence, exhibits more resistance to crack growth.
