摘要：

针对目前市场上的防刺服价格高、柔韧性差、难以在军民领域得到普及的问题,通过在涤纶机织物上涂覆不同粒径的碳化硅(SiC)颗粒制得了一种柔性防刺复合材料,涂覆方式分为单次涂覆和双次涂覆。通过扫描电子显微镜观察和多层动态穿刺性能测试研究了SiC颗粒大小和涂覆方式对该复合材料防刺性能的影响,并且分析了6层单面双层涂覆方式制备的柔性防刺复合材料的耗散吸能模式。结果表明:采用180 μm SiC颗粒制得的复合材料防刺性能最好;当采用双次涂覆方式时,采用单面双层涂覆方式制得的复合材料防刺性能优于采用双面单层涂覆方式;单面双层涂覆方式制备的复合材料主要有2种能量耗散模式。

Abstract:

Due to the high price and poor flexibility of the puncture-proof clothing, it is hard to be popularized in neither military nor civilian field. In this study, a new kind of puncture-proof composite materials (FPPCM) with improved flexibility and low cost was fabricated by coating different sizes of silicon carbide (SiC) particles onto the polyester woven fabric. Through single coating method or double coating method, the obtained composite materials were investigated by scanning electron microscope observation and multilayer puncture-proof dynamic puncture performance test. The results show that the best puncture-proof property of the FPPCM was obtained using 180 μm SiC particles. The influence of the coating method was studied as well. The results show that the FPPCM fabricated by single layer-double sides coating method is better in stab-resistant property than that fabricated by double layer-single side coating method. Moreover, the dissipative energy absorption model of the FPPCM with six layers by single layer-double sides coating method was analyzed. It is found that there are two main energy dissipation models for the FPPCM fabricated by single side-double layer coating method.

Key words: silicon carbide particle, polyester, puncture-proof property, composite materials
