ABSTRACT:
A method for structurally reinforcing a part is disclosed. The method comprising forming a part into a desired shape; placing the part on a holding fixture; introducing a substrate lay-up of a reinforcing material onto at least a portion of the part; placing a flexible sheet impermeable to a resin of the reinforcing material over a portion of the part having the substrate lay-up of said reinforcing material placed on the part, wherein the flexible sheet includes at least one injection port; evacuating all air and vapor from a pocket between the flexible sheet and the part; introducing the resin of the reinforcing material into the pocket through the at least one injection port; allowing the substrate and the resin of the reinforcing material to cure at least partially; and, removing the flexible sheet from the part.
