Preparation and Tensile Properties of Carbon Fiber Reinforced Polyethylene Resin Composite

Abstract

The composite of carbon fiber reinforced polyethylene resin was prepared by using a twin-screw extruder. The effect of carbon fiber content on the tensile properties of the composite of carbon fiber reinforced polyethylene resin was researched. The tensile fracture failure mechanism of composite materials was analyzed. The experimental results indicate that with the increase of the content of carbon fiber in the composite material, the tensile strength and tensile modulus increase gradually. When the carbon fiber content in the composites is 4.02%, compared to the pure polyethylene resin matrix, the tensile strength and tensile elastic modulus is increased by 18.45% and 208.37%, respectively. With the increase of adding amount of carbon fiber and the carbon fiber volume fraction is less than 0.1 in composite material, the stress load subjected by carbon fiber is significantly increased, which is close to the linear relationship.
