Problems solved by technology

[0003] Due to the high inertia of the carbon fiber surface, the composite material prepared by using carbon fiber and resin has the problem of poor adhesion, which is not conducive to the infiltration between the fiber and the resin, thus affecting the mechanical properties of the composite material.
The surface of commercial carbon fiber is generally coated with a layer of sizing agent, which acts as a "bridge" to connect the interface phase between the fiber and the resin matrix and transmit the load. Uniform transfer between resin matrix

Abstract

The invention discloses a method for preparing anti-cutting gloves from a carbon fiber composite material, and relates to the technical field of carbon fiber composite materials. On one hand, oxidized carbon fibers are prepared through oxidation treatment of carbon fibers, and on the other hand, 1,3-bis(3-aminopropyl)-1,1,3,3-tetramethyldisiloxane and terephthalic acid are subjected to a condensation reaction to prepare resin; and by using the two modes, the cohesiveness of the carbon fibers and the resin is improved, and the interface bonding performance of the carbon fiber composite material is improved, so that the reprocessing performance of the carbon fiber composite material and the use quality of the anti-cutting gloves are improved.

Description

Technical field: [0001] The invention relates to the technical field of carbon fiber composite materials, in particular to a method for preparing cut-resistant gloves using carbon fiber composite materials. Background technique: [0002] Carbon fiber is a special fiber composed of carbon elements. It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, heat conduction, and corrosion resistance. It is fibrous in shape and soft, and can be processed into various fabrics. Since the graphite microcrystalline structure of carbon fiber is preferentially oriented along the fiber axis, it has high strength and modulus along the fiber axis. Carbon fiber has a low density, so its specific strength and specific modulus are high. The main purpose of carbon fiber is to be used as a reinforcing material to compound with resin, metal, ceramics and carbon to make composite materials. [0003] Due to the high inertia of the carbon fiber surf...
