Preparation method of carbon fiber strengthened aluminum-base-layer-shaped composite board

Abstract

The invention relates to a preparation method of a carbon fiber strengthened aluminum-base-layer-shaped composite board, and aims to solve the condition that the intensities of aluminum and aluminum alloy are low and the tenacity is poor. According to the preparation method, aluminum powder and carbon fiber cloth are heated, fused and combined, vibrated and pressurized so as to manufacture an aluminum base-layer-shaped composite board, the carbon fiber strengthened aluminum base-layer-shaped composite board is manufactured on a heating and vibrating press machine in a heating, pressurizing and vibrating process, so that a nine-layer structure is formed, an aluminum solution is utilized for wetting the carbon fibers under low temperature, pressure and vibration actions, and a fragility compound can not be formed, so that the organization structure is compact, the tensile strength achieves 144MPa, the elongation achieves 21.2%, the process is advanced, the data is full and accurate, the process flow path is short, and the preparation method is an ideal method for preparing the carbon fiber strengthened aluminum base-layer-shaped composite board.

Description

technical field [0001] The invention relates to a method for preparing a carbon fiber-reinforced aluminum-based composite plate, which belongs to the technical field of preparation and application of nonferrous metal composite materials. Background technique [0002] Aluminum is the main group element of the third period in the periodic table of elements. It is a face-centered cubic lattice without allotropic transformation. It has good ductility, high plasticity, and good formability. It can be processed by various machines, and aluminum and its alloys It also has the advantages of good thermal conductivity, electrical conductivity, light reflection, and no low-temperature brittleness. It can be made into plates and profiles, and is widely used in automobiles, aerospace, electronic communications, computers and other industrial fields; but aluminum and its alloys have low strength and hardness. Low, which greatly affects the application of aluminum and its alloys; in order ...

AI Technical Summary

Problems solved by technology

[0004] At present, the use of carbon fiber reinforced aluminum matrix composites is mainly liquid metal impregnation method. Carbon fiber needs to be soaked in high temperature metal liquid for a long time, which is easy to damage carbon fiber and form brittle compounds on the surface of carbon fiber, which reduces the bonding strength between fiber and metal, and the cost is high. , the process is complex, so that carbon fiber reinforced aluminum matrix composite panels cannot be widely promoted and applied in industry
