Composite material of carbon fibers or carbon fiber powder, and processing process thereof

Abstract

The invention provides a composite material of carbon fibers or carbon fiber powder, and a processing process thereof. The composite material comprises, by mass, (1) 35-55% of a matrix, wherein an unsaturated polyester resin or an epoxy resin is adopted as the matrix, (2) 2-20% of carbon fibers or boron fibers, (3) 5-15% of micro glass balls or silicon carbide balls, (4) 35-55% of carbon fiber powder, and (5) 2-20% of copper powder or copper alloy powder. The composite material of carbon fibers or carbon fiber powder has high specific strength and high specific modulus, wherein the structure member formed from the composite material has characteristics of low density, fine surface burnishing effect, impact resistance, low resistivity, and good electrical conductivity.

Description

technical field [0001] The invention relates to the technical field, in particular to a composite material of carbon fiber or carbon fiber powder and a processing technology thereof. Background technique [0002] Various materials, including metals and non-metals, have emerged as the times require, and the requirements for materials are always in the direction of light weight, multiple functions, high strength, and low prices. With space vehicles, vehicles, machine tools, building structures, etc., the requirements for material technology in the development of modern industry are already very urgent. However, the composite materials provided in the prior art cannot meet higher and higher requirements in terms of specific strength, specific modulus, impact resistance, light structure performance, electrical resistivity and electrical conductivity.
