THE IMPACT PROPERTIES OF HYBRID COMPOSITE MATERIALS (GLASS CARBON/POLYESTER)

Abstract

This work focuses on the preparation of hybrid polymer matrix composite materials by (Hand Lay-Up) method, where the composite material was prepared from the unsaturated polyester resin (UP) as a matrix reinforced by bidirectional woven glass fiber kind (E-glass) with weight fraction of (10%+ 20%+30%) as first group of samples and the second group of samples reinforced with bidirectional woven fiber carbon kind (90-0) with weight fraction of (10%+20%+30%) instead of glass fiber. and the third group of samples reinforced with fiber glass and fiber carbon and polyester of ingredient hybrid. The values of Impact Strength increased with the increases of weight fraction of carbon and glass particles for both types of fibers that used in reinforced; and also results show that impact strength, Bending elastic modulus, Fracture Toughness increase with the increasing of carbon and glass particle size.
