Problems solved by technology

Due to the reaction between titanium alloy and most toughened fibers in high temperature environment, the interfacial products will affect the performance of the material, resulting in the decrease of the mechanical properties of carbon fiber reinforced titanium and composite materials. Therefore, the process requirements for the preparation of fiber toughened titanium alloy composites are more stringent and complex. , the solid-phase preparation method is generally used, but the interface reaction is still relatively violent under high temperature conditions

Abstract

The invention discloses a method for rapidly preparing a carbon fiber reinforced titanium alloy layered composite material. The method comprises the following steps of S1, ultrasonically cleaning carbon fiber cloth and drying; S2, sequentially carrying out sensitization, activation and reduction on the dried carbon fiber cloth, and cleaning and drying; S3, plating nickel on the dried carbon fibercloth to obtain nickel-plated carbon fiber cloth; and S4, laying a nickel-plated carbon fiber cloth layer after the titanium alloy powder is laid on a plasma hot-pressing sintering mold, and then laying a titanium alloy powder layer, sequentially repeating the powder layer and the cloth layer paving process, and obtaining the carbon fiber reinforced titanium alloy layered composite material through discharge plasma hot-pressing sintering. According to the method, due to the fact that the heating rate is high, the heat preservation time is short and the pressure is high in the discharge plasmahot-pressing sintering process, and the isolation effect of the nickel-plated layer on the surface of the nickel-plated carbon fiber cloth to the the carbon fiber and the titanium alloy powder, the carbon fiber reinforced titanium alloy laminar composite material can be rapidly prepared, so that the integrity of the carbon fiber is ensured, and the mechanical property of the carbon fiber reinforced titanium alloy layered composite material is improved.

Description
