Abstract

The invention discloses a preparation method of a carbon fiber-based stab-resistant and chopping-resistant clothes fabric, and relates to the technical field of carbon fiber materials. The carbon fiber-based fabric is prepared by taking a carbon fiber fabric as a substrate and compounding the carbon fiber fabric with epoxy resin twice, and the fabric has the excellent mechanical performance by utilizing the characteristics of high strength and high modulus of carbon fibers; and the brittleness of the carbon fiber fabric is reduced by compounding the epoxy resin, the impact resistance of the carbon fiber fabric is improved, so that the comprehensive use effect of the fabric is further optimized, and the application of the fabric in processing of stab-resistant and chopping-resistant clothes is realized.

Description

Technical field: [0001] The invention relates to the technical field of carbon fiber materials, in particular to a method for preparing a carbon fiber-based anti-stab and anti-slash clothing fabric. 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] The biggest disadvantage of carbon fiber composites is h...
