Layer process.
Further, in the step 4, the good carbon fiber prepreg of paving is used into vacuum bag technique curing molding.
The beneficial effects of the present invention are: solving carbon fiber composite material reflector base can not directly plated film application, carbon
The problems such as fibrous composite poorly conductive leads to not direct coating.Preparation process of the invention, first using good conductivity and
Thermal stability is good and the matched material of carbon fiber composite material reflector, preparation and carbon fiber composite material reflector to be prepared
The identical mold of mirror surface structure, and the surface surface figure accuracy of mold is wanted better than carbon fiber composite material reflector face shape to be prepared
It asks；Then the metal cladding on mold, and paving carbon fiber prepreg on the metal layer carry out curing molding, demoulding obtains gold
Belong to layer and the integrated carbon fiber composite material reflector mirror base of carbon fibre composite substrate, finally to carbon fibre composite
The metal layer of mirror base carries out surface processing, and plating metal reflectance coating obtains carbon fiber composite material reflector.The preparation work
Skill is simple and easy, can integrated molding.
