Composite material and producing mehtod thereof

Abstract

An object of the present invention is to provide a method for producing a composite material that can prevent a powdered additive to be mixed from scattering and control a quantity of the additive dispersed in the composite material. A method for producing a composite material in which an additional material different from a base material is dispersed into a part of the base material comprises the steps of providing a wire rod formed by applying a metallic film to the additional material to be dispersed or by stuffing a metallic tube with the additional material to be dispersed, fixing the wire rod on a surface or into an inside of the base material, and applying stirring along the fixed wire rod with a tool for friction stirring to disperse the additional material into the part of the base material.
