Abstract

The present invention provides a resin member capable of controlling a position and an amount of molten resin produced during the ultrasonic welding, and stabilizing the thickness of the interface so as to stabilize the bonding strength. A resin member contains a thermoplastic resin and is bonded to another resin member by ultrasonic welding. The resin member includes projections that are projected from a surface of a bonding target section of the resin member and melted by application of contact pressure during the ultrasonic welding. The projections include projections having different projection heights from the surface of the bonding target section.

Description

technical field

[0001] The present invention relates to resin parts comprising a thermoplastic resin and joined to each other by ultrasonic welding. Background technique

[0002] Conventionally, structural parts of automobile bodies are made of metal materials such as steel. In recent years, in order to reduce the weight of the vehicle body, the use of structural parts made of resin materials such as carbon fiber mixed fiber reinforced resin (CFRP) has gradually been realized. As a joining method for joining members made of metal materials, there are basically three methods. One is outfitting joining using bolts or the like, the other is bonding using an adhesive, and the other is fusion joining by melting metals. When a component is made of a resin material, the same strong joint as that of a member made of a metal material is required. In particular, in the case of components made of a resin material including a thermoplastic resin, a welding technique of melting and jo...
