摘要
Abstract
In order to consolidate the engineering application foundation of domestic high thermal conductivity mesophase asphalt-based carbon fiber(MPCF)in aerospace field,the properties of domestic MPCF and its com-posites were studied.The micro-morphology of domestic MPCF was characterized by scanning electron microscopy(SEM)and atomic force microscopy(AFM).The surface chemical elements,wettability and surface energy of do-mestic MPCF were measured by X-ray photoelectron spectroscopy(XPS),optical microscopy and surface interface testing instrument.The preparation process of domestic MPCF prepreg was investigated.The mechanical properties,physical and chemical properties and thermal vacuum degassing properties of domestic MPCF composites were evalu-ated.The results show that the roughness of domestic MPCF is higher than that of imported MPCF.The surface chemical activity,wettability and surface energy of domestic MPCF are better than those of imported MPCF.The forming process of domestic MPCF prepreg is subpar,and the interlayer shear strength of domestic MPCF composite(46.69 MPa)is comparable to that of imported MPCF composite,but other properties such as tensile,compression and bending properties are slightly lower than those of imported composite.The thermal vacuum degassing perform-ance of domestic MPCF composite meets the requirements of space environment.The average in-plane thermal con-ductivity of domestic MPCF isotropic composite material is 152.1 W·m-1·K-1,and the thermal conductivity is slightly lower than that of imported materials,but it has more advantages of lightweight and structural-functional in-tegration than the traditional 6063 aluminum alloy heat-expanding structure.关键词
