Heatable vacuum hood device for vacuum evacuation of mordern plastic material, has vacuum hood that is made of flexible plastic material whose temperature is adjusted by electrical heating device

摘要

The device (100) has vacuum hood (110) for providing gas-tight covering during pressing process performed by gas pressure on layer of curable composite substrate applied to solid molded structure. A fibrous structure and a matrix of a curable viscous filling material are introduced into fibrous structure. The hood is made of flexible plastic material whose temperature is adjusted by electrical heating device (120). The heating device is integrated into hood by electrical conductor made of metal braid, carbon fiber yarn, and carbon fiber cord, latex material, elastomer and silicone plastic.
