The current study focus on the multi-phase Shear thickening fluid (STF) treated high-strength fabrics which is an promising material for soft-wall containment casing. Three types of multi-phase STF were manufactured by adding graphene oxide (GO) and carbon nanotubes (CNTs) to a nanosilica suspension system. Steady rheological property tests and yarn pull-out tests were conducted to determine the shear thickening behavior of the multi-phase STFs and inter-yarn friction of their compound fabrics. Ballistic impact tests were conducted using titanium blade-like projectiles. The energy absorption, deformation evolution and damage patterns were investigated. Tests show that the addition of GO and CNTs resulted in a higher initial viscosity, a lower shear rate for onset of shear thickening and a lower thickening ratio. The enhancement of the frictional force is more striking for multi-phase STFs. The GO additives have the highest deformation in the ballistic impact tests, corresponding to the greatest energy absorption with a ballistic performance index 78.3% higher than that of neat fabrics. The results show great potential for reducing the weight of containment casing.

目前的研究集中在经过多相剪切增稠剂（STF）处理的高强度织物上，该织物是用于软壁围护结构的有前途的材料。通过将氧化石墨烯（GO）和碳纳米管（CNT）添加到纳米二氧化硅悬浮液系统中，制造了三种类型的多相STF。进行了稳定的流变特性测试和纱线拉出测试，以确定多相STF的剪切增稠行为及其复合织物的纱间摩擦力。弹道冲击试验是使用钛合金叶片状弹丸进行的。研究了能量吸收，变形演化和损伤模式。测试表明，GO和CNT的加入会导致较高的初始粘度，较低的剪切增厚开始剪切速率和较低的增稠率。对于多相STF，摩擦力的增加更为显着。GO添加剂在冲击试验中具有最高的形变，对应于最大的能量吸收，其弹道性能指数比纯织物高78.3％。结果显示出减轻安全壳重量的巨大潜力。
