Open the CIPO recordAbstract From the Canadian patent
A hollow fiber reinforced part especially body closures, for vehicles is made by applying preforms to a hollow thin-, walled support which has been preshaped to the general configuration of the body closure. The support is then depressurized and the support/preform subassembly placed into a mold. The mold is closed and the support again pressurized. Then resin is injected into the mold to impregnate the fibrous pieces of the preforms. Once the resin cures the, mold is opened and the part removed.
