저온 고속 조건하의 플라스틱 소재 파손 특성에 관한 연구

Automotive cockpit module should be designed with considerations of design trend and its function. It has to meet regulations like domestic safety standard 88, ECE 21, FMVSS 201 as functional part. It also has to meet passenger airbag deployment requirement requested by OEM. In case of passenger airbag deployment test, it is performed under temperature controlled conditions like cold, room, hot temperature. The deployment test is done in very short time. FE analysis is used to predict the performance of passenger airbag deployment in advance. To do FE analysis of passenger airbag deployment, rate dependent material data with fracture characteristics under temperature condition is required. This study is about the rate dependent material properties with fracture characteristics under temperature condition.
