Abstract

Abstract: Adhesive bonding is the most important way to connect carbon fiber reinforced plastic (CFRP) drive shaft with other components. Due to the uncertainty of bonding strength, it has become a common choice to study the rationality of adhesive layer design by using finite element software. In this study, the failure criterion, stiffness balance design criterion and shear strength design method of adhesive joint have been studied. Meanwhile, in order to improve the efficiency of finite element analysis of similar CFRP-metal adhesive joints, the parameter optimization plug-in is developed by using the Python programming language interface provided by ABAQUS software. The plug-in provides automatic pre-and post-processing function for finite element analysis of CFRP-metal bonded joints, the optimization function of stiffness balance design criterion and shear strength design method of adhesive joint is realized. Finally, the accuracy and reliability of the simulation plug-in are verified through experiments.

Key words: stiffness balance, secondary development, carbon fiber, adhesive joint, composites
