A punching rivet method can fasten sheets without pre-drilled hole, and out-of-plane deformation of joints is also small. This method is carried out by using a rivet and a rivet holder. The punching rivet method has been applied to fastening of an acrylic sheet and A5052 sheet. In this study, the rivet and the rivet holder were improved to enhance the joint strength. Tensile test was carried out for the improved joints. From experimental results, the joint strength was higher than the strength of the acrylic base material because of the seating pressure on seat surface between the rivet head and the rivet holder. Furthermore, when the joint was made under the condition that the upper sheet is acrylic and the under sheet is A5052, the joint strength of joints with improved rivet was higher than the joint strength of previous one.
