Novel carbon fiber composite material

Abstract

The present invention discloses a novel carbon fiber composite material, which comprises, by weight, 30-34 parts of carbon fiber, 21-27 parts of epoxy resin, 17-24 parts of aqueous epoxy resin emulsion, 14-20 parts of an accelerator, 10-15 parts of a toughening agent and 1-3 parts of a curing agent. The material is able to meet the requirements of carbon fiber composite rope matrix resin, and has high comprehensive utilization of fiber strength; and the addition of aqueous epoxy resin emulsion effectively protects the carbon fiber, avoids the friction and wear between the fiber bundles, and enhances the bending resistance of the composite material.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a novel carbon fiber composite material. Background technique [0002] Carbon fiber and its composite materials have a series of excellent properties, such as high specific strength, high specific modulus, corrosion resistance, fatigue resistance, electrical conductivity, heat transfer, etc. Carbon fiber and its composite materials can be used not only as structural materials to bear loads, but also as functional materials. Carbon fiber rope also has various excellent properties, and has incomparable advantages over ordinary ropes. But so far, there is no research report on carbon fiber composite ropes in China. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, provide a new type of carbon fiber composite material, and meet the basic needs of the market. [0004] In order to achieve the above-mention...
