극저온 환경에서 탄소섬유강화 복합재료의 수지조성변화에 따른 인장 물성 측정

Abstract

In this study, carbon riber reinforced polymeric (CFRP) composites with differnt rein composition were manufactured and resin formulation in composite materials were presented through tensile tests for cryogenic use. Thermo-methanical cyclic loading( up to 6 ctycles)was applied to CFRP unidirectional laminate specimens from room temperature to -150. Tensile tests were then performed at 0150 using an environmental test chamber. In addition, matrix-dominant properties such as the transverse and in-plene shear characteristics of each omposite model were measured at 0150 to examine the effects of resin formulation on their interfacial properties. The tensile tests showed that the composite models with large amounts of bisphenol-A epoxy and CTBN modified rubber in theri resin composition had good mechanical performance at cryogenic temperature(CT).
