Carbon fiber product molding/decorating integrative process

Abstract

The invention relates to a carbon fiber product molding / decorating integrative process. The process comprises the steps of placing a carbon fiber laminate comprising a carbon fiber prepreg, a surfacedecorative film and a protective film on a lower mold of a mold, closing an upper mold and the lower mold of the mold to seal the cavity of the lower mold under the action of the upper mold and the carbon fiber laminate, heating the carbon fiber laminate while applying suction to the carbon fiber laminate on the cavity by vacuuming, and applying pressure to the carbon fiber laminate in the same direction as suction direction with high pressure gas, and increasing the heating temperature to the carbon fiber prepreg curing temperature, maintaining temperature and pressure to obtain a molded product. High pressure gas is used for replacing a traditional upper mold, and the effect of uniform pressure can be achieved by utilizing the air pressure uniform distribution characteristic in the sealed mold cavity, the partial breakage or uneven deformation of the carbon fiber prepreg and the surface decorative film in the molded angular region is avoided, the quality and molding efficiency of thecarbon fiber product are improved, and a complex product can be molded.

Description

technical field [0001] The invention relates to the field of composite material molding, in particular to an integrated carbon fiber product molding / decoration process. Background technique [0002] Carbon fiber composite material (CFRP) has the characteristics of "light weight and high strength", and has been widely used in aerospace, automobile, electronics, machinery, chemical industry, textile, sports equipment and leisure products and other fields. The current molding processes used in carbon fiber products, such as resin transfer molding (RTM process), autoclave molding process, etc., are time-consuming and costly, seriously affecting production efficiency, and the molding surface quality is not good. Carbon fiber products need to undergo subsequent decoration processes after molding, generally including grinding, dusting, painting and other processes. These processes have low automation, high labor intensity, poor working conditions, low production efficiency, and lar...
