Problems solved by technology

Carbon fiber reinforced polyethylene has very high specific strength, but due to the smooth surface of carbon fiber, less active functional groups, low surface energy, surface chemical inertness, and poor wettability with resin matrix, the interface adhesion of composite materials is weak, which seriously affects the The overall excellent performance of composite materials, and the chemical inertness of polyethylene also makes the adhesion between carbon fiber and matrix resin poor, thus affecting the transfer of stress

Abstract

The invention discloses carbon-fiber-reinforced polyethylene master batch. The master batch comprises following components by weight: 20-40% of polyethylene resin, 60-80% of carbon fiber, 0.5-3% of a coupling agent, 1-3% of a lubricant and 0.1-1% of an anti-oxidant. Beneficial effects of the master batch are that: compared with the prior art, the master batch is used for production of polyethylene materials, and the master batch has characteristics of high material strength, good toughness, high corrosion resistance, simple production process, using convenience, and the like. The carbon fiber is subjected to surface treatment by polyacrylonitrile, so that the adhesion force of the carbon fiber and a resin substrate is largely improved, and the carbon fiber plays a good reinforcing function.
