真空袋成型工艺是指在单面刚性模具上以真空袋膜包覆玻纤、泡沫等干性材料；

Vacuum bag forming process refers to coating dry materials such as glass fiber and foam with a vacuum bag film on a single-sided rigid mold; according to the corresponding diversion strategy, the gas in the mold cavity is eliminated under vacuum negative pressure, and the resin is used to realize resin flow and penetration A process method for impregnating dry material and then curing into composite material glass steel

Vacuum bag molding process refers to a single-sided rigid mold with a vacuum bag film wrapped glass fiber, foam and other dry materials, according to the corresponding conductive strategy, vacuum negative pressure to eliminate the gas in the mold cavity, the use of resin flow and penetration to achieve resin to dry material impregnation, and then cured into a composite glass and steel process method.

The technology of vacuum bag molding is to dry the dry materials such as glass fiber and foam on a single-sided rigid mold by vacuum bag film. According to the corresponding diversion strategy, remove the gas in the mold cavity under vacuum negative pressure, use resin flow and infiltration to achieve resin impregnated with dry materials, and then solidify into a composite material FRP.<br>
