Abstract
A process and method for manufacturing fiber reinforced composite structures without trapping volatiles in the resin matrix. Volatiles from the curing cycle are absorbed into a silicone rubber layer,and a gas impermeable barrier layer outside the silicone rubber layer prevents autoclave atmosphere from permeating into the part. The process is to layer the finished ply build-up, with a ply of FEP (fluorinated ethylene propylene), a layer of silicone rubber to absorb the volatiles, and a layer of impermeable elastomer. The layer of fluoroelastomer is bonded to the silicone rubber to form a reusable, impermeable elastomeric vacuum bag, eliminating the need for disposable edge and surface breathers.
