Manufacturing method for carbon fiber composite material

Abstract

The invention discloses a manufacturing method for a carbon fiber composite material. The manufacturing method comprises the steps that a sizing agent is applied on carbon fiber fabrics, wherein electromagnetic-induction nano particles are doped in the sizing agent; the sizing agent and the carbon fiber fabrics are heated in an electromagnetic heating mode and are enabled to adhere to each other; the bonded sizing agent and carbon fiber fabrics are subjected to cutting and laminating operation, are preheated by adopting the electromagnetic heating mode and then are put into a pre-forming mold to be subjected to pressing shaping operation so as to obtain a pre-formed body; the pre-formed body is placed into a forming mold to be subjected to mold closing pressurization operation, and the pre-formed body and the forming mold are heated to a preset injection temperature in the electromagnetic heating mode; resin is injected into the forming mold, and the pre-formed body and the forming mold are heated to a preset curing temperature in the electromagnetic heating mode; and after curing molding cooling, demoulding is carried out to obtain the carbon fiber composite material. The method has the advantages that the rate of temperature increase by heating is high, the product manufacturing efficiency is high, and the energy consumption and the manufacturing cost are low.

Description

technical field

[0001] The invention relates to the technical field of materials, in particular to a method for manufacturing carbon fiber composite materials. Background technique

[0002] High-performance carbon fiber composites have excellent comprehensive properties such as specific strength, high specific modulus, and corrosion resistance, and have been widely used in aerospace, ships, weapons, and sporting goods. At present, carbon fiber composite materials are gradually developing from high-end markets such as aerospace to wind power, automobiles and other industrial fields. Especially in the field of automobiles, as the requirements for energy saving and environmental protection become higher and higher, the requirements for lightweight automobiles extend from racing cars to ordinary automobiles and large buses. Reducing the weight of automobiles can reduce fuel consumption and exhaust emissions. For new energy vehicles It can effectively improve the driving mileage...
