The self-piercing riveting experiments were carried out on the composite plates with four different fiber layers made of[CC]2s,[GG]s,[CCG]s and[GCC]s and 5052 aluminum alloy plates. The surface forming quality and profile forming quality of the joints were analyzed. The tensile and bending tests were carried out on universal tensile testing machine, and the failure modes were analyzed. The results show that when the static tensile tests for the composite plates with four different fiber layers are carried out by using the same rivet, the tensile strength of the composite plates is[CC]2s,[GG]s,[CCG]s and[GCC]s, and the failure displacement is[CC]2s,[CCG]s,[GG]s and[GCC]s from large to small. The bending strength is[CC]2s,[CCG]s,[GG]s and[GCC]s from large to small when the same rivet is used for bending test. In static tensile test,[CC]2s and[GCC]s fail due to rivet pulling off from composite plate, and[GG]s and[CCG]s fail due to rivet head fracture. In bending test,[GG]s,[CCG]s and[GCC]s have different degrees of fiber breakage due to shearing pressure, while[CC]2s is delamination.
