A kind of preparation method of high-performance bulletproof composite material

Abstract

The invention discloses a high-performance bulletproof composite material preparation method. Multi-component composite type high-performance special fiber is utilized as main reinforcement, a high-performance toughened resin matrix is utilized as an adhesive, and the multi-component composite type high-performance special fiber and the high-performance toughened resin matrix are integrally formed into a bulletproof material body through high temperature hot pressing. High-performance ceramic is adhered to a bullet receiving face of the bulletproof material body, so that a bulletproof level of the bulletproof material body is level-5 or more; the ratio of carbon fiber volume content of a bullet receiving face layer to carbon fiber volume content of a bullet opposite face layer is smaller than 1. The material can achieve better penetration resistance and can reduce non-penetration injury caused by a large back protrusion amount to a human body under the premise of guaranteeing smaller surface density. The defects that a traditional metal material is heavy and a single-component bulletproof composite material has generally lower bulletproof performance are overcome.

Description

technical field [0001] The invention relates to a bulletproof technology, in particular to a preparation method of a high-performance bulletproof composite material. Background technique [0002] Traditional bulletproof materials are mostly high-strength metals, ceramics, fiberglass and other materials. If these materials want to obtain good bulletproof effect, generally need sufficient thickness, thereby cause the bulletproof device of making to be heavy, bring adverse influence to the design and manufacture of bulletproof device, bring various restrictions to the design of bulletproof device. [0003] Fiber-reinforced resin-based composite materials are widely used in the field of composite materials due to their excellent performance. Advanced composite materials are an important part of aerospace high-tech products. They can effectively reduce the weight of aircraft, launch vehicles, missiles and satellites, increase the effective Payload and range, lower costs. With t...
