Vacuum manufacturing method of carbon fiber composite material preform for hydrogen energy automobile

Abstract

The invention discloses a vacuum manufacturing method of a carbon fiber composite material preform for a hydrogen energy automobile, and relates to the technical field of carbon fiber composite material preform manufacturing. The vacuum manufacturing method specifically comprises the following steps, S1, preparing a preform mold; S2, preparing a preform; S3, heating the fiber cloth; S4, performing vacuum shaping on the preform; S5, cooling the fiber cloth; and S6, trimming the preform. According to the vacuum manufacturing method of the carbon fiber composite material preform, the composite fiber cloth can be pressed to form a required shape by matching a vacuum negative pressure mode with the preform mold, the manufacturing operation is simple and convenient, the method can adapt to manufacturing of preforms with different shapes only by replacing the preform mold, so that the production range is expanded, the preform mold adopts a wood or plastic mold, so that the investment cost is reduced, and the economic benefit is improved.
