タイトル(掲載誌)航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-413
一般注記KEVLAR-49 was introduced to Japan by E.I. Dupont in February 1972 as a reinforcement for composites, which has a tensile strength similar to carbon fibers. KEVLAR-49 composite consists of matrices of epoxy(Epon 828). Static mechanical tests included determination of tensile and flexural strength, Young’s modulus, interlaminar shear strength and Poisson’s ratio. Poisson’s ratio was determined by using the laser holography method and the strain gage method. The repeated flexural fatigue property was determined by using the NAL type fatigue tester of a constant load type. KEVLAR-49 composites have lower flexural strength than carbon fiber composites. In order to improve this property we developed a hybrid of KEVLAR-49 and carbon fiber composite and found that the hybrid has sufficient flexural and fatigue strength for use as structural material.
