Prediction of Residual Strength of CFRP Subjected to High Velocity Impact
고속충격을 받는 CFRP 복합재료의 잔류강도 예측
Abstract
The purpose of this research is to propose a model for the prediction of residual strength. For this purpose, two-paremeter model based on Caprino's is developed and formulated by the ratio of indentation due to impact and normalized residual strength. The damage zone is considered only as an indentation. Impact tests are carried out on laminated composites by steel balls. Test material is carbon/epoxy laminate. The specimens are composed of
