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: A method for forming an investment casting core comprises cutting a patterned core precursor from refractory metal-based sheet. The cutting forms recast along the cuts. An oxide is grown on non-recast areas. The recast is substantially chemically removed but substantially leaving the oxide. The core precursor may then be shaped.
