Abstract

The invention provides a preparing method for continuous carbon fiber enhanced nickel-based composite materials. A method that cured nickel powder adheres to the surface of continuous carbon fiber through organogel is adopted, the thickness of an adhering nickel layer on the surface of the carbon fiber can be controlled, accordingly, the content and the distance of the carbon fiber in composite materials after hot pressed sintering are controlled, the carbon fiber is distributed in a nickel base body in parallel, and the high-carbon-fiber-content nickel-based composite materials can be prepared. According to the preparing method, the complex carbon fiber surface nickel plating technology is omitted, the cost is extremely low, operation is easy, and industrial production can be achieved. The strength of the carbon fiber enhanced nickel-based composite materials obtained through the provided preparing method is obviously superior to the strength of carbon fiber enhanced nickel-based composite materials prepared through existing methods, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a preparation method of continuous carbon fiber reinforced nickel-based composite material. Background technique [0002] Nickel-based composite materials are widely used in aircraft, ships and other industries. They have very good high-temperature strength, oxidation resistance, thermal fatigue resistance, and thermal erosion resistance. They can replace nickel-based super heat-resistant stainless steel to make various parts of turbine engines Components work at high temperatures. Carbon fiber reinforced metal matrix composites have strong anisotropy when reinforced in one direction, and exhibit high static strength and good resistance to damage in the fiber direction. In continuous carbon fiber reinforced nickel-based composites, long fibers are load-bearing components. Since the long fibers have high strength and elastic modulus in the axial direction,...
