METHOD OF MAKING AND USING A SPRAY-FORMED NATURAL RUBBER VACUUM BAG |
摘要 |
Disclosed is a method for making a membrane for use as a vacuum bag, a natural rubber vacuum bag made using such methods, and methods for using such a natural rubber bag to form a composite article. One method can include providing a substantially non-porous working surface having a desired shape for forming a vacuum bag, spraying at least one layer of a natural rubber liquid over at least a portion of working surface, and solidifying the natural rubber liquid to form a membrane having a shape substantially corresponding to that of the working surface. The membrane formed being elastically deformable and substantially impermeable for functioning as a vacuum bag in Vacuum Assisted Resin Transfer Molding, debulking, compaction, or similar processes. |
