A new technique developed by NASA enables the preparation of metal/composite hybrid laminates, also known as fibermetal laminates (FML), through a one-step processing method. Currently FMLs are prepared by a compression process using a press or autoclave with metallic layers sandwiched between layers of glass or graphite prepreg (preimpregnated fibers with a matrix resin). NASA’s process essentially eliminates the need to produce prepreg prior to the production of a hybrid laminate. It also allows the production of large, net shape structures that were previously not possible with autoclave or press technologies due to size constraints. Essentially, it involves an infusion process whereby matrix resin transversely infiltrates fiber layers that have been sandwiched between plies of metal foil containing flow pathways to produce a metal/composite hybrid laminate. The infiltration can be accomplished using pressure (resin transfer molding [RTM]), or a vacuum induced pressure differential (vacuum assisted resin transfer molding [VARTM]).
