Failure Analsys of Wrapped Pin Joint of Composite and Metal

Abstract:

By filament winding technology, a pin hole can be formed in the process of composite manufacturing through wrapped fiber tow around pin, so fiber tows around the pin hole are continued. The paper presents the failure analysis for this kind of pin hole. The experimental results and numerical results show that the pin hole has a good tensile bearing ability. According to Hashin criteria, numerical results show that main failure modes are fiber tensile failure and matrix tensile failure which are agreed with the experimental results.
