Evaluation of Mode II Interlaminar Fracture Toughness for Carbon Fabric/Epoxy Composite for Tilting Train

틸팅차량용 탄소섬유직물/에폭시 복합재의 모우드 II 층간파괴인성 평가

In this study, mode II interlaminar fracture phenomena of carbon fabric/epoxy composite for tilting train were investigated. The end notched flexural specimen containing an artificial crack with the thickness of 12.5fl11l was used. The mode II interlaminar fracture toughness was evaluated through a three point bending test and the fractured surfaces were examined through a scanning electron microscope. The experimental results obtained in this study would be applicable in the design and structural analysis of the composite structures.
