摘　　要：CFRP/TC4异质材料黏结界面主要由金属表面、黏结剂以及复合材料表面组成,该界面是异质材料融合构件的核心部位,其界面黏结强度的优劣,对该类异质材料融合构件的长寿命和高可靠性会产生显著影响。本文主要针对TC4金属表面微结构对界面黏结强度的影响进行研究,基于Abaqus建立剪切力作用下的重叠黏结有限元模型,确定优选后的三角形结构主要参数为宽度、高度以及开槽方向与剪切受力方向之间的夹角,进而采用响应面Box-behnken法设计仿真试验并建立金属表面微结构与界面切应力之间的映射模型,并基于方差分析验证了该模型的有效性。通过该研究,揭示了金属表面微结构参数对界面切应力的影响规律。The bonding interface of CFRP/TC4 heterogeneous material is mainly composed of metal surface,binder and composite material surface.The interface is the core part of the heterogeneous material fusion component.The quality of the interface bonding strength will have a significant impact on the long life and high reliability of the heterogeneous material fusion component.In this paper,the influence of TC4 metal surface microstructure on interface bonding strength is studied.Based on Abaqus,the finite element model of overlapping bonding under shear force is established.The main parameters of the optimized triangular structure are determined to be width,height and the angle between the groove direction and the shear force direction.Then,the response surface Box-behnken method is used to design the simulation test and establish the mapping model between the metal surface microstructure and the interface shear stress,and the validity of the model is verified based on variance analysis.Through this study,the effect of metal surface microstructure parameters on interfacial shear stress is revealed.
