CZM(Cohesive Zone Model)을 이용한 철도차량용 직물 복합재의 모우드 I 층간파괴의 해석적 연구
Finite Element Analysis and Validation for Mode I Interlaminar Fracture behavior of Woven Fabric Composite For a Train Carbody Using CZM(Cohesive Zone Model)
초록
The Mode I interlaminar fracture toughness of woven fabric carbon/epoxy and glass/epoxy composites for a train carbody was measured and FEM analysis was conducted. The woven fabric epoxy composite manufactured by hand lay-up, has high stiffness and strength, good resistance for impact, fatigue, corrosion and in-plane failure. The DCB(Double Cantilever Beam) specimen made of woven fabric epoxy composite had the size of 180mm
