In order to study the failure characteristics of dissimilar materials under different connection methods and promote the application of hybrid joint in engineering, the static tensile mechanical properties of CFRP/Aluminum single lap joints were studied, including adhesive, rivet and hybrid joints. Different kinds of adhesive and rivet were considered in adhesive joints and rivet joints and tensile mechanical properties of them were discussed firstly. Then, two kinds of them were selected respectively for the preparation of hybrid joints where the interactive effect was studied. Besides, the effect of riveting direction on the mechanical properties of rivet and hybrid joints were analyzed. The results show that from the characteristics of load-displacement of joints, adhesive joint presents the character of brittle fracture, rivet joint shows the ductile fracture characteristics and hybrid joint includes both characteristics where the adhesive layer will fracture firstly. Besides, the riveting direction has an important influence on the mechanical properties of riveted and hybrid joints. The joint with the riveting insertion from the CFRP substrate side exhibits better mechanical performance than that from the aluminum substrate side. In the study of hybrid joints, the combination of strong adhesive and weak riveting show the strongest positive interaction so that its material utilization rate is the highest. The study can provide some insights for the connection design between composite and metal materials in practice.
