Abstract

The invention relates to a carbon fiber surface quick composite reinforcing treatment method including the steps of: 1) detecting parameters of carbon fibers; 2) selecting the type of a micro-particle bombardment processing machine; 3) selecting the type of micro-particles, wherein the micro-particles may be spherical or ellipsoidal particles; 4) controlling the operation parameters of processing the carbon fibers by the micro-particle bombardment processing machine; 5) selecting an irradiation processing machine; 6) controlling the operation parameters of the irradiation processing machine; 7) bombarding and irradiating the carbon fibers; 8) performing performance detection to the irradiated carbon fibers; and 9) preparing a composite material. The method is quick and high-effectively and can reinforce the surface of the carbon fibers and improve the adhesion force between the carbon fibers and a resin base body; and furthermore, the method can be used for quickly preparing the carbon fiber reinforced composite material and also can be applied for preparing the composite material on site, thus effectively increasing production speed and improving productivity, and ensuring that the mechanical performance of the composite material satisfies use demand.

Description

Technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a fast composite strengthening treatment method for carbon fiber surface. Background technique [0002] Carbon fiber and its composite materials have excellent mechanical properties such as high specific strength, high specific modulus, high temperature resistance, corrosion resistance, etc. However, in the manufacturing or production process, the pros and cons of the above mechanical properties largely depend on the surface of the carbon fiber Processing technology. At present, common carbon fiber surface treatment technologies include liquid-phase oxidation, gas-phase oxidation, electrochemical oxidation, plasma oxidation, etc. Among them, liquid-phase oxidation is a method that uses liquid-phase media to oxidize the surface of carbon fibers. Oxidation treatment is very effective in improving the shear strength of the interface layer of carbon fiber / resin com...
