Abstract: The present invention related to a method for providing a composite structure and the composite structure formed thereby. The method broadly comprises the steps of: providing a core structure (12) formed from a non-metallic composite material in a substantially uncured state; applying a fluoroelestomer film (14) in a substantially uncured state over surface portions of said core structure (12); placing a metallic structure (16) over a portion of said core structure, said metallic structure having inner surfaces which contacts said fluoroelastomer film (14), and molding said composite structure under conditions of heat and pressure for a time sufficient to co-cure said fluoroelastomer film (14) and said non-metallic core structure material (12) and to form a bond between said fluoroelastomer film and said inner surfaces of said metallic structure. The method of the present invention may be used to manufacture original metal/composite ssssstructures as well as to refurbish metal/composite structures such as fan exit guide vanes for jet engines.
