摘要
Abstract
The morphologies,surface energies and surface chemical properties of the domestic T700 grade carbon fiber and the T700S carbon fiber were characterized by using scanning electronic microscopy (SEM),inverse gas chromatography(IGC) and X-ray photoelectron spectroscopy (XPS)respectively.The mechanical properties of the two carbon fibers/QY9611 composites were also discussed.The results indicate that the surface properties of carbon fibers have an important influence on the interfacial properties of composites.The interfacial properties of domestic T700 grade carbon fibers/QY9611 composite at room temperature/dry conditions are superior to T700S/QY9611 composite.The toughness of domestic T700 grade carbon fibers/QY9611composite is outstanding as well.The value of CAI has reached the level of foreign advanced composite IM7/5250-4.After hydrothermal treatment,the interfacial strength of domestic T700 grade carbon fibers/QY9611 composite is equal to that of T700S/QY9611 composite.It shows that domestic T700 grade carbon fibers/QY9611 composite has good hydrothermal-resistant properties.关键词
