Hybrid Laminates Made by Vacuum Assisted Resin Transfer Molding

Fiber metal laminates (FMLs) are multi-component materials utilizing metals, fibers and matrix resins.  Tailoring their properties is readily achievable by varying one or more of these components.  Established FMLs like GLARE utilize aluminum foils, glass fibers and epoxy matrices and are manufactured using an autoclave. Two new processes for manufacturing FMLs using vacuum assisted resin transfer molding (VARTM) have been developed at the NASA Langley Research Center (LaRC).  A description of these processes and the resulting FMLs will be presented.
