摘要：

Mechanical performance together with progressive failure process and failure modes of riveted, adhesively bonded and hybrid joints connecting CFRP and aluminum alloy with various overlap length were investigated. Experimental results showed that hybrid joints presented superior performance in terms of peak load and energy absorption, which increased by up to similar to 380%, 434% and similar to 19%, 56% respectively compared with solely riveted and bonded joints. Typical failure evolution photographs were taken with high speed camera for analyzing progressive failure process. Final failure modes of hybrid joints included rivet shear fracture, CFRP compressive deformation, adhesive failure, cohesive failure and light-fiber-tear failure.
