Abstract

The invention discloses a carbon fiber cloth-titanium alloy composite material and a preparation method thereof. The method comprises the steps of Step 1, pretreating a carbon fiber cloth; Step 2, electroplating copper on the surface of the carbon fiber cloth, wherein the surface of the carbon fiber cloth is coated with the copper through an electroplating method; Step 3, placing the copper-plated carbon fiber cloth and a titanium alloy piece into a die in a certain sequence; and Step 4, obtaining the carbon fiber cloth-titanium alloy composite material in the required shape finally through a spark plasma sintering (SPS) method. The carbon fiber cloth-titanium alloy material prepared by the method is good in composition, the copper has the good interface wetting effect and effectively prevents the interface reaction of titanium and carbon, constituents of the titanium alloy are adjustable, the distribution of the carbon fiber cloth is controllable, and carbon fibers are firmly combined with a substrate. The composite material is high in specific modulus and interface bonding strength, simultaneously, compared with the titanium alloy, the composite material is low in density and high in static and dynamic compression strength, and the composite material is a high-performance structure material.

Description

technical field [0001] The invention relates to a preparation process of carbon fiber cloth copper plating and metal composite material, belongs to the field of metallurgy technology, and in particular relates to a preparation method of carbon fiber cloth-titanium alloy composite material. Background technique [0002] Due to its high specific strength and excellent corrosion resistance, titanium alloys are often used in the fields of aviation, weapons, automobiles and medicine. With the development of science and technology, the performance requirements of titanium alloy materials in various application fields are getting higher and higher. Materials not only need to have high strength, low density, high stiffness, good plasticity and toughness, but also need to have good dynamic mechanical properties. However, it is difficult to meet the above requirements only through titanium alloy materials. Therefore, researchers began to consider the preparation of titanium alloy comp...
