Problems solved by technology

However, it is difficult to avoid the connection problems between thermoplastic composite materials and traditional metal materials in the application process
[0003] At present, most of the connection methods between thermoplastic composite materials and metals are welded by laser and ultrasonic welding. However, the interface bonding strength of the joints obtained by the above welding methods is low, which limits the use of thermoplastic composite materials.

Further improved Interfacial bond strength between metal sheets and fiber-reinforced thermoplastic resin matrix composites. The invention integrates the fiber-reinforced thermoplastic resin-based composite material and the metal sheet into one body, has simple operation, short processing period, high production efficiency and is suitable for batch production.

Description

technical field [0001] The invention relates to the technical field of thermoplastic composite material and metal connection, in particular to a fiber-reinforced thermoplastic resin matrix composite material-metal sheet connector and a preparation method and application thereof. Background technique [0002] Thermoplastic composites have the advantages of excellent toughness, impact resistance and damage tolerance, remolding and reprocessing, and long storage time of prepregs. They are gradually used in aerospace, rail transit, medical equipment and other fields. However, thermoplastic composite materials are difficult to avoid in the application process involving connection problems with traditional metal materials. [0003] At present, most of the connection methods between thermoplastic composite materials and metals use laser, ultrasonic, etc. welding. However, the interface bonding strength of the connectors obtained by the above welding methods is low, which limits the...
