Abstract

The invention discloses a method for preparing a cladding coating on the surface of a carbon fiber reinforced thermoplastic composite material by using a laser-assisted SHS process, which relates to a method for preparing a cladding coating. The purpose of the present invention is to solve the existing problems of complex process, low joint strength, easy deformation of resin and high cost in the existing method for preparing metal coating on the surface of carbon fiber reinforced thermoplastic composite material. Method: pre-treat the carbon fiber reinforced thermoplastic composite material; 2. spread the cladding powder on the surface of the treated carbon fiber reinforced thermoplastic composite material, then compact the cladding powder, and then irradiate in a vacuum chamber to obtain The carbon fiber reinforced thermoplastic composite material with a cladding coating formed on the surface is to complete a method of preparing a cladding coating on the surface of a carbon fiber reinforced thermoplastic composite material using a laser-assisted SHS process. The invention can obtain a method for preparing a cladding coating on the surface of a carbon fiber reinforced thermoplastic composite material by using a laser-assisted SHS process.

Description

technical field

[0001] The invention relates to a method for preparing a cladding coating. Background technique

[0002] Carbon fiber reinforced thermoplastic composites (Fiber Reinforced Thermo Plastics, CRTP for short) have high specific strength and specific stiffness, strong designability, good fatigue fracture resistance, corrosion resistance, good structural dimensional stability, and are convenient for large-area integral forming and special Unique advantages such as electromagnetic properties play an increasingly important role in high-tech manufacturing fields such as aerospace and automobiles.

[0003] Among CRTP materials, although carbon fibers are resistant to high temperatures, the melting point of the matrix resin is low, and it begins to soften at 200-300°C. The commonly used thermoplastic resins are polyethylene terephthalate, polyphenylene sulfide, polyether ketone and polyether. ether ketone etc. The melting point of polyethylene terephthalate is 270°C, ...
