Abstract

The invention discloses a bonding and riveting method between a carbon fiber composite material plate and an aluminum alloy plate. The bonding and riveting method adopts the carbon fiber composite material plate with a through hole and the aluminum alloy plate for gluing; and riveting is performed before adhesive is not cured; a half-hollow rivet is tapped; air in a hollow part of the half-hollowrivet is exhausted in the riveting process under a punch effect; the adhesive flows into the hole of the rivet for closing; and curing is performed after completion of self-punching riveting process to finish bonding and riveting connection. The bonding and riveting method can improve the strength of a traditional carbon fiber composite material connecting process, and solves the damage problem ofa glue layer by riveting in a traditional bonding and riveting technology; and meanwhile, the air in the hollow part can be emptied in the riveting process, and the hole of the rivet is closed afterthe adhesive flows in, so that the corrosion resistance of a joint is improved.

Description

technical field [0001] The invention relates to the technical field of riveting a carbon fiber composite material plate and an aluminum alloy plate, in particular to a riveting device between a carbon fiber composite material plate and an aluminum alloy plate and a self-piercing riveting method before a cement is cured. Background technique [0002] With the diversification of automotive, aviation and military materials, a single application of traditional metal materials can no longer fully meet the needs of use. The rapid development and wide application of composite materials make the application of materials more perfect. Compared with traditional metal materials and other composite materials, carbon fiber composite materials have the advantages of high strength and high specific strength, which can significantly improve the overall performance of structures in structural applications, but the connection relationship between carbon fiber composite materials and metal mat...
