摘要： 碳纤维树脂基复合材料(CFRP)具有轻质、高强、高模量等优异性能,在航空航天领域有广阔的应用前景。界面作为连接树脂基体和碳纤维(CF)增强体的桥梁,是影响复合材料力学性能的重要因素。针对碳纤维与树脂的模量差异过大的问题,提高界面相的模量使两者的模量平稳过渡,提高应力传递效率,是改善界面性能的有效策略。本文主要综述了近年来刚性界面相、刚柔界面相的构筑方法及其对复合材料增强效果的研究进展,并对碳纤维树脂基复合材料界面相存在的问题进行了讨论,对今后界面增强的研究方向进行了展望。

Abstract: Carbon fiber reinforced polymer (CFRP) have excellent properties such as light weight, high strength, high modulus, and have wide application prospect in the fields of aerospace. As a bridge connecting the resin matrix and carbon fiber (CF) reinforcement, the interphase is an important factor affecting the mechanical properties of composite. Aiming at the problem that the modulus difference between carbon fiber and resin matrix is too large, it's an effective strategy to improve the interfacial properties by improving the modulus of interphase to make the modulus transition smoothly and improve the stress transfer efficiency. The construction methods of stiffened interphase and rigid-soft interphase in recent years are mainly summarized in the paper. Finally, some issues of the interphase of CFRP are discussed and the future trends of interfacial reinforcement research are prospected.
