Failure Analysis of T800 Carbon Fiber Composite Joint Structure With Double Bolts

Abstract

In this paper, the progressive damage model of T800 carbon fiber composite double-bolt joint based on Hashin criterion was established based on the finite element analysis. By changing the bolt diameter, the numerical simulation of the strength change of the joint was carried out. The damage evolution process was studied and the corresponding verification test research was carried out. Finally, the damage and failure process of the T800 carbon fiber composite double-bolt joint is given, and the strength optimization design scheme is proposed.
