Outline
Carbon fiber reinforced polymer （CFRP） has the characteristics of high specific strength/modulus and strong designability， which has been widely used in aerospace and transportation. CFRP is mainly composed of carbon fiber， resin matrix and the interface between them. As a component of CFRP， the interface poses great influence on the properties of the composite. Due to the smooth surface morphology and chemical inertness as well as significant difference in the elastic modulus between the matrix， the interfacial compatibility of CFRP is rather poor. Therefore， searching for suitable interfacial modification methods has become a hot research topic. In this paper， interface modification methods of CFRP， including the conventional approaches and state-of-the-art approach based on multi-scale interface microstructure construction， as summarized. In general， the multi-scale interface microstructure construction method is advantageous over the conventional methods in regard to interface modification effect， which can change the physical and chemical properties of the fiber surface and alleviate the stress concentration caused by the large modulus difference between the fiber and the resin. Outlook is given on the trend of composite interfacial modification method based on multi-scale interfacial phase construction：exploring accurate interface normal characterization methods combined with micro and nano technologies， while developing controllable interface microstructure construction processes， and exploring a set of efficient and low-cost multi-scale interface construction methods， ultimately achieving the practical engineering application of the multi-scale interface microstructure construction method.
