Abstract

The invention discloses a method for preparing a high-performance-fiber-reinforced hard bulletproof composite material. According to the method, woven fabrics of high-performance carbon fibers, aramid fibers and high-strength polyethylene fibers serve as prefabricated members, the reinforcing effect of the high-performance carbon fibers and the aramid fibers and the bonding effect of high-strength polyethylene molten into a matrix at a certain temperature are fully used, the prefabricated members are compression-molded through a compression molding device, and the composite material of the carbon fibers, the aramid fibers and the high-strength polyethylene fibers is obtained. The obtained composite material has different mixing synergistic effects, the bulletproof performance and the mechanical property can be effectively improved, and the composite material has good observability and a wide pressure regulation range. The quality of the inner structure of the composite material is easy to guarantee, the boundary dimension accuracy is high, and therefore the composite material is widely applied to the field of industrial composite materials.

Description

technical field [0001] The invention relates to a hard bulletproof composite material with high-performance fiber as a reinforcing material and melt-type high-performance fiber as a matrix, especially a preparation method of a hard bulletproof composite material of carbon fiber, aramid fiber and high-strength polyethylene fiber. Background technique [0002] High-performance fiber-reinforced composite material is a kind of material with high bending strength and impact toughness, extremely high fatigue strength, damage resistance and excellent designability and formability. Carbon fiber, aramid fiber, and high-strength polyethylene fiber are three high-performance fibers with high specific strength and good impact resistance. They are made of a type of bullet-resistant composite material with good impact resistance and strong design protection performance. It has certain versatility and excellent toughness and is widely used in the field of bulletproof composite materials. ...
