Abstract

The invention relates to a bonding method for the surface of a metal material and the surface of a composite material, and belongs to the technical field of bonding the surface of a metal material and the surface of a composite material. The invention uses laser technology to replace the traditional methods of artificial organic solvent + pickling + water washing + drying, etc., and solves the problems of high manual operation intensity, difficult process quality control, poor product consistency, low efficiency, serious environmental pollution, and damage to personnel health. The invention optimizes the laser processing technology, simplifies the complex cleaning process, and improves the bonding strength of the surface of the metal material and the composite material.

Description

technical field [0001] The invention relates to a bonding method for the surface of a metal material and the surface of a composite material, and belongs to the technical field of bonding the surface of a metal material and the surface of a composite material. Background technique [0002] Composite materials are mainly composed of two or more different substances combined in different ways, which can give full play to the advantages of various materials and overcome the defects of a single material. Excellent, chemical corrosion resistance, good thermal stability, etc., are widely used in the manufacture of aircraft, satellite antennas, large launch vehicle shells, space shuttle structural parts and other fields. In practical applications, composite materials need to be bonded with metal materials to improve product performance. However, after mechanical processing of metal materials such as aluminum alloy and stainless steel, there are likely to be machine-added liquid an...
