Impact Strength of Interply and Intraply Hybrid Laminates Based on Carbon-Aramid/Epoxy Composites

Abstract

Hybridization plays an important role to achieve multi-functionality for the particular composite applications. Hybrid composites allow designers to obtain desired physical and mechanical properties that cannot be provided from a single type of fiber reinforcement such as combining high strength, light weight and good impact resistance together. In this study, the effect of hybridization on the Charpy impact strength was investigated considering the aramid and carbon fiber reinforced polymer (FRP) composites. For this reason, interply, intraply hybrid composite laminates, aramid FRP and carbon FRP were manufactured by hand lay-up followed by vacuum bagging method. The composite laminates were tested according to ISO 179-1: 2010 Standard using Charpy impact testing machine. The results were given comparatively and shown that energy absorption capacity of intraply hybrid composite laminate was found better than others.
