  • Method and apparatus for vacuum bag molding of composite materials
    Patent number: 5106568
    Abstract: A method and apparatus for vacuum bag molding of composite materials which eliminates the need for a porous release sheet. Prepregs are placed on a forming tool and overlayed with at least one sheet of nonporous material and a breather sheet and then enclosed within an impermeable membrane. The volume enclosed by the membrane is evacuated, the resin in the prepregs is outgassed, and the prepregs are coalesced to mold the prepregs to the shape of the forming tool. After curing the resin, the temperature is reduced and the resultant article is removed from the forming tool.
