芳纶无纬布防刺性能初探
|
摘要
针对目前国内外对芳纶无纬布防刺性能研究较少的情况,以及目前防刺服柔软度较差的事实,从织造芳纶无纬布的水性胶粘剂的胶膜本身耐穿刺性能入手,并对无纬布进行后期处理,开创性地将芳纶无纬布应用于防刺领域。确定水性胶粘剂C具有一定硬度并且与芳纶纤维匹配较好,为防刺用芳纶无纬布的胶粘剂配方;经过后期处理后,通过准静态穿刺性能测定不同胶含量的单层无纬布刺穿力,确定树脂含量为24%～27%时,芳纶无纬布具有最优的刺穿力,此时无纬布面密度为225 g/m~2;通过动态穿刺性能测试确定,将芳纶无纬布叠加至34层(单层面密度为225 g/m~2),加一层4.5 mm厚EVA泡沫(面密度为200 g/m~2)作为缓冲层,其防刺性能在-20℃～55℃范围内均满足GA 68—2008标准的测试要求,此时防护层面密度(含缓冲层)仅为7.85 kg/m~2,且具有较高的柔软度,可任意角度折叠180°。
As few studies are available on the stab performance of aramid UD cloth, and the fact that the wear comfortableness of stab-resistant body armor is poor, starting with the stab-resistance of the adhesive film, which is applied to weaving the aramid UD cloth, and post-processing of the aramid UD cloth, pioneering in the use of aramid UD cloth in the field of stab-resistant. The adhesive C with a certain hardness and better matching with aramid fiber, is the final formula. By using the quasi-static stab experiment to measure the piercing force of the different glue content, it is confirmed that the content of glue is 24%～27%, the piercing force of aramid UD cloth is the best, and the single layer density is 225 g/m~2. By using the dynamic puncture performance, the aramid UD cloth overlying to 34 layers(the single layer density is 225 g/m~2), adding one layer of 4.5 mm EVA(the density is 200 g/m~2) as the buffer layer, the stab performance meets the standard requirements of 《GA 68—2008》, within the temperature range from-20 ℃ to 55 ℃. The density of the protective layer(with the buffer layer) is only 7.85 kg/m~2, with a high softness, can be folded to 180 degrees at any angle.
