摘要
Abstract
Toray T700S and domestic T700 carbon fibers were used as reinforcements to prepare bismaleimide composites by autoclave moulding. Surface physical and chemical states of the carbon fibers, as well as interfacial of the composites and interlaminar shear strength were studied. The results show that the domestic T700 carbon fibers can form better physical adhesion with the resin matrix, which have more grooves on the surface and higher surface roughness than T700S carbon fibers. Although the two kinds of oxygen functional groups of carbon fiber are equivalent, the domestic T700 carbon fibers can form better chemical adhesion with the resin matrix, as they have more oxygenic functional groups than T700S carbon fibers. Hence, the interfacial shear strength of domestic T700 carbon fibers is higher than that of T700S carbon fibers by about 14 ％, and the interlaminar shear strength is higher by about 19％.关键词
