Abstract:
PROBLEM TO BE SOLVED: To provide a method of forming a composite structure such as a vane-shaped structural body and a composite structure formed by the method. SOLUTION: A forming method consists of a step of providing an uncured core structure 12 formed of a non-metal material, a step of forming a material layer 14 for an uncured fluoroelastomer film on the surface of the section of the core structure 12, a step of disposing a metal structure 16, the inner face of which is brought into contact with the material layer 14 on a part of the core structure 12 and a step of forming a composite structure under heat and pressure for the time sufficient for current the core structure body 12 and the material layer 14 together and forming the both between the metal structure 16 and the material layer 14. The composite structure can be used for repairing a metal/composite structure such as a fan outlet guide vane for a jet engine, manufacturing an original metal/composite structure and the like by the arrangement.
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.
