Embodiment Construction
[0013] The technical scheme that this specific embodiment adopts is: its preparation method is as follows:
[0014] 1. Preparation of bulletproof material prefabricated parts: carbon fiber is used as raw material, and three-dimensional bulletproof material prefabricated parts are prepared at one time by adopting three-dimensional weaving process (using three-dimensional weaving structure is conducive to increasing the fiber volume content in bulletproof composite materials and enhancing the strength of bulletproof materials. Impact resistance, anti-multiple elastic properties, compression resistance, etc.);
[0015] 2. Composite molding of bulletproof material prefabricated parts: using phenolic resin as the matrix, adopting a high-pressure (0.1-2MPa) impregnation process, the phenolic resin matrix and the three-dimensional bulletproof material prefabricated parts are subjected to high-pressure impregnation composite molding, the impregnating time is 10-60min, and the impregnat...

Abstract
A preparation method of a carbon or carbon composite bulletproof material relates to the technical field of preparation of bulletproof materials. The preparation method comprises the following steps: 1, making a bulletproof material prefabricated member; 2, carrying out composite molding on the bulletproof material prefabricated member; 3, carrying out high temperature sintering on the bulletproof material prefabricated member; 4, repeatedly dipping a bulletproof material, and carrying out high temperature sintering; 5, carrying out in situ sintering on the bulletproof material; and 6, taking out the bulletproof material after the bulletproof material is naturally cooled, and post-processing the bulletproof material. The bulletproof material prepared through the preparation method has the characteristics of light weight, high strength, high hardness, high compression strength, high bulletproof grade, and good multiple-bullet resistance, and can be used in protection of ultrahigh speed steel bombs and armor-piercing bullets.
Description
technical field [0001] The invention relates to the technical field of bulletproof material preparation, in particular to a preparation method of carbon or carbon composite 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 protect high-s...
