열습환경 하에서의 적층각도 변화에 따른 CFRP 모자형 단면부재의 압궤특성 = Collapse Characteristics of CFRP Hat Shaped Members under the Hygrothermal Environment According to Stacking Angle

다국어 초록 (Multilingual Abstract)

It is important to satisfy the requirements and standards for the protections of passengers in a car accident. There are lots of studies on the crushing energy absorption of structure members in automobiles. We have investigated collapse characteristics and moisture absorption movements of CFRP(Carbon Fiber Reinforced Plastics) hat shaped sectional members when CFRP laminates are under the hygrothermal environment. The absorbed energy, mean collapse load and deformation mode were analyzed for side members which absorbed most of the collision energy. Therefore we have made a static collapse experiment to research into the difference of absorbed energy and deformation mode between moisture absorbed specimen and non-moisture absorbed specimen.
