Problems solved by technology

Due to the smooth surface of carbon fiber, few active functional groups, low surface energy, surface chemical inertness, and poor wettability with the resin matrix, the interface adhesion of the composite material is weak, which seriously affects the overall excellent performance of the composite material; another On the one hand, the chemical inertness of polyethylene also makes the adhesion between carbon fiber and matrix resin poor, thus affecting the transmission of stress

Abstract

The invention discloses a flame-retardant carbon-fiber-reinforced polyethylene composite material which comprises the following components in parts by weight: 80-100 parts of high-density polyethylene, 10-20 parts of low density polyethylene, 15-20 parts of carbon fiber, 5-15 parts of coupling agent, 0.5-1 part of plasticizer, 0.1-0.5 part of dispersing agent and 10-15 parts of flame retardant. The composite material has the advantages of high strength, high bearing pressure and poor thermal deformation in the high-density polyethylene, and also has the advantages of favorable impact resistance and favorable toughness in the low-density polyethylene. The composite material has the characteristics of flame retardancy and high strength.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant carbon fiber reinforced polyethylene 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, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electrical conductivity, heat transfer and small thermal expansion coefficient, so they can be used as both structural materials and Used as a functional material. [0003] As the reinforcing fiber of composite materials, carbon fiber has broad prospects and is widely used in various fields of national economy. Due to the smooth surface of carbon fiber, few active functional groups, low surface energy, surface chemical inertness, and poor wettability with the resin matrix, the interface adhesion of the composite material is weak, which...
