Impact Properties of Laminating Type in EVA and CFRP

摘要

This study deals with Carbon Fiber Reinforced Plastic (CFRP), which is receiving much attention in various fields because of its excellent properties such as high specific strength, specific stiffness, and corrosion resistance. Since CFRP is vulnerable to impact damage owing to its brittle nature, this study intends to overcome this vulnerability by using Ethylene Vinyl Acetate (EVA), which possesses excellent cracking resistance and flexibility. In this study, impact tests were conducted by fabricating test specimens through various lamination methods using the impact theory. In addition, the size, shape, and tendency of a defect in impact-tested specimens were identified using an IR thermal imaging camera through the thermal imaging theory.
