Abstract:
A preform is infused with a resin to form a composite laminate. The preform is placed between a mold and a vacuum bag. An offset tool is placed to permit the vacuum bag to lift away from a surface of the preform in a controlled amount. A charge of the resin is injected between the vacuum bag and the preform to lift the vacuum bag off the surface of the preform and move the vacuum bag toward the offset tool, so that the resin occupies a volume between the vacuum bag and the preform. The preform is infused with the resin by applying a super-atmospheric pressure to an outer surface of the vacuum bag to transport the resin from the volume between the vacuum bag and the preform into a volume within the preform. The resin in the preform is cured, forming the composite laminate.
