Abstract

The invention provides a vacuum bag compression forming assembly to solve the problems that a vacuum bag compression forming method is high in energy consumption, low in efficiency, and incapable of manufacturing larger-sized products due to space limitation of drying equipment in the prior art. The vacuum bag compression forming assembly comprises a mold, a surface heating piece and a flexible sealing membrane. The sealing membrane can be connected with the mold in a sealing mode, and a closed sealing cavity used for conducting forming treatment on a to-be-formed piece is formed between the sealing membrane and the mold; and the surface heating piece is arranged in the sealing cavity and covers the surface of the to-be-formed piece so as to conduct heating on the surface of the to-be-formed piece. Meanwhile, the invention discloses a vacuum bag compression forming method and a fiber composite. The vacuum bag compression forming assembly is high in efficiency and low in energy consumption, and more importantly, the vacuum bag compression forming assembly cannot limit the size of formed products, and can be used in a wide range.

Description

technical field [0001] The invention relates to a vacuum bag pressing forming component, a vacuum bag pressing forming method, and a fiber composite material. Background technique [0002] The existing vacuum bag molding (Vacuum bag process) process is a closed pre-forming cavity that uses a combination of a single-sided rigid pre-forming mold and a vacuum bag made of elastic soft film. The fiber cloth is pre-impregnated with resin The formed prepreg is filled in the preforming cavity, and then the preforming cavity is evacuated, and the resin adsorbed in the prepreg is better combined with the fiber cloth by means of negative pressure suction, and the resin on the fabric is realized through vacuum suction. Dip liquid molding technology. [0003] Usually, according to the above-mentioned vacuum bag molding method, the prepreg is filled in the preform cavity, and after the preform is vacuumed and pressed, it is necessary to heat the whole in an oven to cure the resin in the ...
