Abstract

The invention discloses a preparation method for a superhard carbon / carbon bulletproof material. The method comprises the following steps: step 1, preparation of a prefabricated component of the bulletproof material; step 2, composite molding of the prefabricated component of the bulletproof material; step 3, high-temperature sintering of the prefabricated component of the bulletproof material; step 4, repeated impregnation and high-temperature sintering of the bulletproof material; step 5, in-situ sintering of the bulletproof material; and step 6, natural cooling of the bulletproof material and post-treatment of the bulletproof material after the bulletproof material is taken out. The bulletproof material prepared by using the method has the characteristics of lightweight, high strength, high hardness, high compression strength, a high bulletproof level, good resistance to multiple bullets, etc., and can be used for protection from superspeed steel-core bullets and armor-piercing bullets.

Description

technical field [0001] The invention relates to the technical field of high-performance fiber technology processing and production, in particular to a preparation method of a superhard carbon / carbon 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 mai...
