Method for joining and reforming of metal and thermoplastic composites

Abstract

The invention discloses a method for jointing and reforming of metal and thermoplastic composites. The method comprises the following steps of providing a thermoplastic composite component, specifically, the surface of the thermoplastic composite component comprises a first area; superposing and fixing a metal component on the thermoplastic composite component, specifically, the metal component comprises a jointing region area overlapping the first area; rapidly heating an overlapping area of the jointing area and the first area to a jointing temperature; quickly placing the heated thermoplastic composite component and metal component into a die covering the first area and the jointing area to close the die and form a metal-thermoplastic composite jointing re-formed component; taking out the metal-thermoplastic composite jointing re-formed component; and when a heating heat source is a lamp source, setting a heat adjusting partition wall between the lamp source and the metal componentthat the lamp source faces to adjust the heating heat of the metal component. Accordingly, the metal and the thermoplastic composites can be jointed and formed to improve the local mechanical properties, compressive strength, wear resistance and overall dimensional accuracy stability of fiber reinforced composites.

Description

technical field [0001] The invention relates to a method for joining and forming a metal and a thermoplastic composite material, in particular to a method for joining the metal and the thermoplastic composite material by applying radiant heating to the metal, softening the thermoplastic composite material, and then pressing the metal into the thermoplastic composite material. and reshaping methods. Background technique [0002] Thermoplastic composites (Fiber Reinforced Thermoplastic, FRTP) have high toughness, good impact resistance, short manufacturing cycle, excellent chemical resistance, low moisture absorption, convenient storage of prepregs and no limitation of use time. Can be processed repeatedly. [0003] Thermoplastic composites have quickly gained acceptance as a replacement for many materials such as die castings, metal assemblies, traditional plastics in markets including industrial equipment, automotive, consumer products, and more. High impact strength, bett...

Problems solved by technology

However, the technology in this patent document only involves simple joining operations, and there is no concept of convenient forming

Moreover, the prior technology uses induction heating, which can only heat a small area of ​​the metal parts. When the local joint area is large, the working time will be prolonged, and the welding quality and dimensional accuracy will be affected.
