폴리우레탄 모재를 적용한 CFRR 기계적 특성 연구
The Study of Mechanical Properties of CFRR(Carbon Fiber Reinforced Rubber) with Polyurethane Matrix
초록
The purpose of this study is to investigate the shear modulus, the shear strength at failure and the failure process of QLS(quadruple-lap shear) Test specimen were made of two different fiber contents CFRR and HTPB based polyurethane matrix. The CFRR specimen were prepared with 6.16% chopped carbon fiber and 11.6% chopped carbon fiber. We carried out the shear tests for three types of specimen. The shear modulus and strength of the CFRR was inspected with the increasing contents of chopped carbon fiber. In the other hand the shear strain of the CFRR was inspected with the decreasing contents of chopped carbon fiber.
