Low-cost light-weight highly-bulletproof B4C/SiC composite ceramic bulletproof plate and preparation method thereof

Abstract

The invention relates to a low-cost light-weight highly-bulletproof B4C / SiC composite ceramic bulletproof plate and a preparation method thereof. The bulletproof plate is made from silicon carbide granulated powder by pressing, drying, debinding and sintering. The silicon carbide granulated powder is composed of, by weight, 60%-73% of silicon carbide micropowder, 6%-8% of phenolic resin, 0.5%-2% of carbon black, 0.5%-2% of graphite, 5%-16% of boron carbide and 10%-12% of polyvinyl alcohol. By adoption of the silicon carbide granulated powder as a raw material for preparation and adoption of a hydraulic forming machine for pressing, drying, debinding and sintering, the low-cost light-weight highly-bulletproof B4C / SiC composite ceramic bulletproof plate prepared according to the method is high in production efficiency, low in production cost and available for continuous production.

Description

technical field

[0001] The invention relates to a low-cost light weight high ballistic performance B 4 The invention discloses a C / SiC composite ceramic bulletproof plate and a preparation method thereof, belonging to the technical field of ceramic preparation. Background technique

[0002] Body armor is a body protective equipment commonly used by soldiers, policemen, security guards and other special personnel, and it belongs to military and civilian dual-use products. Body armor is generally composed of an inner ceramic bulletproof plate and a fiber material that wraps the ceramic bulletproof plate to increase wearing comfort. The ceramic bulletproof plate is an important part of the body armor, and the bulletproof performance of the ceramic bulletproof plate directly determines the performance of the body armor. With the continuous development of bulletproof materials, people have higher and higher requirements for bulletproof performance, weight, wearing comfort and p...
