Fatigue performance of a self-piercing rivet joint between aluminum and glass fiber reinforced thermoplastic composite

摘要: Abstract Lightweight structures are more and widely used in the automotive industry due to growing importance of environment regulations related CO2 emissions. In this context saving weight, composites offer an alternative metals because they can achieve a better stiffness weight ratio. A problematic becomes crucial: which process be join efficiently composite metallic parts? An innovative way would application self-piercing riveting thermoplastic composite–metal structure. Since does not require pre-drilled hole, time is short. Nevertheless, generates damage such as fiber cutting delamination. The aim work evaluate fatigue strength PA6.6-GF (Glass Fiber reinforced Polyamide 6.6)/Aluminum assembly joined by riveting. Experimental results show that SPR joint high resistance on uniaxial shearing test. at 2 · 106 cycles than half static. Joint manufacturing parameters like rivet shape were investigated. Some tests performed under severe environmental conditions temperature. This study shows have less influences impact type test stresses evolution useful for failure modes analyses.
