Metal and thermoplastic composite joining and reshaping methods

Abstract

The invention discloses a method for joining and reshaping a metal and a thermoplastic composite material. The steps include: providing a thermoplastic composite material piece, one surface of which includes a first region; laminating and fixing a metal piece on the thermoplastic composite material piece In the above, the metal part includes a joint area that is placed on the first area; the superimposed area of ​​the joint area and the first area is rapidly heated to a joint temperature; the heated thermoplastic composite material part and the metal part are quickly inserted into the first The molds in the area and the joint area are molded together to form metal and thermoplastic composite joint reshaped parts; then take out the metal and thermoplastic composite joint reshaped parts from the mold; when the heating source is a light source, it can A heat-adjusting partition wall is set between the pair of metal parts to adjust the heating heat of the metal parts; according to this, the metal and the thermoplastic composite material are joined and formed to improve the local mechanical properties of the fiber-reinforced composite material, improve the compression strength, and Wear and overall dimensional accuracy stability.

Description

technical field [0001] The invention relates to a method for jointing and forming a metal and a thermoplastic composite material, in particular to a method for joining and forming a metal and a thermoplastic composite material after heating the metal with radiation and softening the thermoplastic composite material, and then pressing and forming the metal with a mold 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, easy storage of prepregs, and no time limit for use. Can be processed repeatedly. [0003] Thermoplastic composites have rapidly gained acceptance as replacements for many materials such as die castings, metal assemblies, and traditional plastics in markets including industrial equipment, automotive, consumer goods, and more. High impact strength, better surface quality...

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.
