A kind of preparation method of pottery/pottery hard ballistic material

Abstract

The invention discloses a preparation method of pottery / ceramic hard bulletproof material, which comprises a bulletproof material prefabricated part and ceramic resin, the bulletproof material prefabricated part is connected with ceramic resin, the bulletproof material prefabricated part uses SiC ceramic fiber as raw material, and the bulletproof material prefabricated The parts are prepared at one time by three-dimensional weaving technology, and the ceramic resin is based on polycarbosilane / xylene resin; the preparation method of the pottery / pottery hard bulletproof material proposed by the present invention first combines the bulletproof material prefabricated part with the ceramic Resins are compounded together, and then impregnated and high temperature for many times, and finally the mixture of bulletproof material preforms and ceramic resin is heat treated under the protection of inert gas. The ceramic / ceramic hard bulletproof material made by the complete process has light weight. , high strength, high hardness, high compressive strength, high bulletproof level, good anti-multiple bullet performance, suitable for the protection of high-speed bullets.

Description

technical field [0001] The invention relates to a high-performance fiber technology processing and production technology, in particular to a preparation method of pottery / ceramic hard bulletproof material. Background technique [0002] At present, bulletproof materials are mainly divided into three types, namely soft bulletproof materials, semi-hard bulletproof materials, and hard bulletproof materials. Soft bulletproof materials are mainly fiber-reinforced composite materials prepared from high-performance fibers (aramid fibers, ultra-high molecular weight polyethylene fibers, etc.), and are mainly used to protect low-speed bullets (the bullet speed is about 500m / s, and the bullet type is lead core bombs). The general structure of semi-rigid bulletproof materials is to use hard materials (special steel, ceramic plates, etc.) Mainly steel core bullets). Hard bulletproof materials are mainly hard materials (special steel, ceramic plates, etc.), which are mainly used to pro...

Problems solved by technology

[0003] However, at present, our country has not made very good progress in the research and development of bulletproof materials for ultra-high bullet speed (a bullet speed exceeding 800m / s, bullet types include steel core bullets, armor-piercing bullets, etc.)

Under the impact of ultra-high-speed bullets, the existing bulletproof materials will be punctured, the bulletproof ceramic plate is brittle and broken, and the surface density of the bulletproof material is too high, resulting in heavy weight. In the event of simultaneous impact, the integrity of the ballistic material is not guaranteed
