Problems solved by technology

At the same time, carbon fiber is also used as an inert reinforcing material. People have done more research on how to combine carbon fiber and epoxy resin and apply it to the above-mentioned fields. However, the adhesion between carbon fiber and matrix resin is poor, and it is easy to separate from the matrix resin, resulting in premature composite materials. damage, the shear strength of the prepared composite material is low, so that the performance of the composite material cannot be fully exerted
At present, it is common to use carbon

Abstract

Provided are an abrasion-resisting epoxy resin/carbon fiber composite coating and a preparation and coating method thereof. The composite coating is formed by curing a carbon fiber fabric arranged in a matrix solution, wherein the matrix solution consists of 64-66.5 parts by weight of epoxy resin, 32-33.5 parts by weight of polyamide resin, a butanone solution, a methylbenzene solution and 1.5-2.5 parts by weight of nano inorganic filler modified by a silane coupling agent, the proportion of the volume of the butanone solution to the total weight of the epoxy resin is 2.4 mL:1g, and the proportion of the volume of the methylbenzene solution to the total weight of the polyamide resin is 2.4 mL:1g. The composite coating is applied to a cushioning material formed on the steel block surface. The carbon fiber fabric, spherical nano TiO2, layered nano-montmorillonite and epoxy resin matrix form a firm net crosslinking structure, the interface bonding force is strengthened, and carbon fiber is not easily pulled out from the composite coating in the friction process. The surface roughness of the composite coating is further reduced, and the abrasion-resisting performance of the composite coating is improved.

Description

technical field [0001] The invention relates to an epoxy base / carbon fiber composite material, in particular to an anti-wear epoxy resin / carbon fiber composite coating and a preparation and coating method thereof. Background technique [0002] Epoxy resin is a thermosetting polymer material with high strength, good bonding performance, excellent heat resistance, corrosion resistance and load-carrying capacity. It is widely used in coatings, electrical insulation materials and structural materials. It plays an important role in shipbuilding, electrical and electronics, machinery manufacturing and national defense. With the rapid development of the aviation industry, the application of epoxy resin in these areas continues to expand, and higher requirements are put forward for its friction and wear properties. At the same time, carbon fiber is also used as an inert reinforcing material. People have done more research on how to combine carbon fiber and epoxy resin and apply it t...
