| Abstract: |
| The carbon fiber (CF) / silicone rubber (MVQ) / fluorine rubber (FKM) composites were prepared in this paper, in which the blend of fluorine rubber and silicone rubber was used as the matrix, the carbon fiber was used as the reinforcement. The best formula and curing conditions of preparing composites were determined by testing Mooney scorch of the mixed-rubber and mechanical properties of the composites. The morphology structures of the composites were studied by scanning electron microscope (SEM) and infrared spectrum (IR) analysis. The results showed that the best formula of carbon fiber / silicone rubber / fluorine rubber composites was 90 phr(parts per hundred rubber)fluorine rubber, 3 phr 3# curing agent ( N,N-Dicinnamylidene -1,6- hexanediamine ), 10 phr silicone rubber, 2.5 phr coupling agent KH590 ( 3-mercaptopropyl trimethoxysilane ), 8 phr carbon fiber and the length was 12 mm. First curing conditions were at 170℃ under 10 MPa for 30 minutes, and post curing conditions were at 200℃ for 2 hours. Si-O-Si and Si-O-C bonds formed after the fiber was treated with coupling agent, which improves the compatibility of the composites. |
