Mechanical Properties of CFRP/EVA Composites According to Lamination Ratio

Abstract: Carbon fiber reinforced Plastics (CFRP) composite materials have excellent mechanical characteristics such as specific strength, specific stiffness, and corrosion resistance. However, the greatest disadvantage for the application of CFRP is its weakness to shock. Therefore, when CFRP is applied to members of structures that require safety of people such as airplanes and automobiles, they can receive impact damage by colliding with various types of materials such as small stones or fragments. In this study, tensile test was performed according to the test specifications and method specified in the ASTM standard at different lamination ratio and method of CFRP and EVA (Ethylene Vinyl Acetate) sheet which shows excellent characteristics in the flexibility of crack resistance to analyze the mechanical characteristics of the CFRP/EVA hybrid material and the existence of defects in the combination between CFRP and EVA.
