质轻、高强的碳纤维增强环氧树脂基复合材料在航空航天、交通运输、能源等领域中得到广泛的应用。界面组成及结构是影响碳纤维复合材料物理化学性能的主要因素，碳纤维表面改性是增强碳纤维复合材料界面性能与力学性能最有效的途径之一。近年来的研究结果表明，比表面积较大、结构多样的多孔材料可以提高碳纤维的表面能和表面粗糙度，能够改善复合材料的界面性能。对近些年用不同种类的多孔材料改性碳纤维的研究成果进行了简单介绍，并总结了其对碳纤维复合材料的界面增强效果，以期为未来多孔材料增强碳纤维复合材料的研究提供参考。

Carbon fiber reinforced epoxy resin matrix composites with light weight and high strength are widely used in aerospace, transportation, energy and other fields. The composition and structure of the interface are the main factors affecting the physical and chemical properties of composites. Surface modification of carbon fiber is one of the most effective ways to enhance the interfacial properties and mechanical properties of carbon fiber composites. In recent years, it's been found that porous materials with large specific surface area and diverse structures can improve the surface energy and surface roughness of carbon fibers and improve the interfacial properties of composites. This paper briefly introduces the modification of carbon fiber with different kinds of porous materials in recent years, and summarizes the interfacial strengthening effect of carbon fiber composites, which provides reference significance for the future research of porous materials reinforced carbon fiber composites.
