The research trends at home and abroad of interfacial connections mechanism and interfacial regulation of fiber-reinforced thermoplastic composites/metals are reviewed, including adhesion and mechanical bonding mechanisms.The main bonding force types of the adhesion mechanism are briefly summarized, and the reasons for the weak bonding interface under the adhesion mechanism are discussed. Four kinds of mechanical interface control methods, including mechanical method, chemical method, metal surface additive treatment and laser processing, are focused on. The use of chemical method will cause certain harm to the environment, and it is difficult to accurately control the morphology and size of the microstructure. At present, the method of metal surface additive preparation of microstructure is difficult to achieve complete anchoring and easy to deform resulting in stress concentration. The use of high energy density laser coarsening, cleaning and introducing chemical groups on the metal surface can regulate the microstructure morphology at different scales such as millimeter, micron and nanometer, and the improvement effect on the joint strength is much higher than that of sandblasting, shot blasting, sandpaper grinding, milling and other mechanical methods. Ultrafast pulsed laser has very short interaction time with the material, which has small thermal effect, and can process cross?cale composite structures. Compared with other metal surface treatment methods, ultrafast laser surface treatment can improve the joint strength to a greater extent.
