金属表面微结构对CFRP/TC4界面黏结强度的影响分析
The Influence Analysis of Metal Surface Microstructure on CFRP/TC4 Interfacial Bonding Strength
摘要
Abstract
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.关键词
