Abstract
To improve the mechanical properties of high modulus carbon fibers, the interface bonding abilities of cyanate ester, epoxy 5228 and epoxy 4211 with carbon fibers were studied. In this paper, SEM, AFM, micro-dissoci-ater and all-purpose mechanical tester were used to investigate surface micro configuration of carbon fibers, and the micro-bonding of resin matrix and carbon fiber surface. The macro mechanical properties of composites were also studied. It is found that with the increase of carbon fiber modulus, defects and channels on the surface decrease, surface activity drops and the bonding strength with resins is weaked. The bonding properties decrease with the order of modified cyanate ester, epoxy 5228 and epoxy 4211. The higher the bonding strength of resin with fiber, the better the mechanical capabilities of composites.关键词
