A Study on the Mechanical Property Evaluation of Carbon/Epoxy Composite Material for Aerospace Application

우주항공용 탄소/에폭시 복합재료의 기계적 특성 평가에 관한 고찰

This paper presents the work peformed in a program developing composite material which properties satisfy structural and thermal requirements for aircrafts and spacecrafts. In the aerospace vehicle structures, the specific strength of the materials is one of the important requirements and this is why polymer matrix composite material with reinforced carbon fiber is widely used. However, the mechanical properties of the composite material have been known to be dependent on processing and this difficulties in evaluation have caused a lot of mechanical tests for each batch.
