Silicon carbide composite bulletproof material and preparation method thereof
The invention provides a silicon carbide composite bulletproof material and a preparation method thereof. The silicon carbide composite bulletproof material is prepared from the following quasi-raw materials in parts by weight: 60-90 parts of alpha-SiC powder, 8-15 parts of beta-SiC powder, 20-30 parts of boron carbide powder, 0.8-1 part of a first dispersing agent, 0.5-0.8 part of a second dispersing agent, 10-15 parts of an organic auxiliary agent and 0.5-2 parts of a sintering auxiliary agent. The preparation method comprises the following steps: dispersing powder, proportioning, performing water-based spray granulation, performing dry-pressing molding, and performing pressureless sintering. Alpha-SiC is used as a matrix, beta-SiC and boron carbide are used as reinforcing phases, beta-SiC is used for improving the toughness and strength of silicon carbide ceramic, boron carbide is used for enhancing the hardness performance of the silicon carbide ceramic, and the mechanical property of the composite bulletproof material is greatly improved.
本发明提供一种碳化硅复合防弹材料及其制备方法，包括以下重量份准原料：α‑SiC粉体60‑90份，β‑SiC粉体8‑15份，碳化硼粉体20‑30份，第一分散剂0.8‑1份，第二分散剂0.5‑0.8份，有机助剂10‑15份，烧结助剂0.5‑2份。通过粉体分散、配料、水基喷雾造粒、干压成型、无压烧结工艺制作而成。采用α‑SiC作为基体，β‑SiC和碳化硼作为增强相，其中β‑SiC用于提高碳化硅陶瓷的韧性和强度，碳化硼用于增强碳化硅陶瓷的硬度性能，大大提高复合防弹材料的力学性能。
