Mechanical Properties of Hybrid Woven Carbon/E-Glass/Polypropylene Thermoplastic Prepreg Composites

An increased request in composite materials at low prices with high specific properties has contributed to the development of hybrid thermoplastic composites. In this study, intra-ply, inter-ply and intra-ply/inter-ply hybrid thermoplastic composites are developed by using hybrid woven Carbon/Polypropylene (PP), E-glass/PP and Carbon/E-glass/PP prepregs and their behaviors under axial loading are compared with non-hybrid composites. The intra-ply/inter-ply hybrid composites, which have equable and uniform fiber placement/fiber fractions, provide the highest tensile strength and modulus values. The intra-ply/inter-ply hybrid composite in which the delamination is limited to a narrow region provides high tensile strength/modulus values and therefore this composite is considered as damage tolerant material
