研究了剪切增稠液(STF)不同稀释比对STF/UHMWPE 材料抗高速冲击性能的影响。按照V (剪切增稠液)∶V (无水乙醇)(abs)＝1∶1、1∶2、1∶3、1∶4对 STF 稀释，制备4组 STF/UHMWPE材料靶样，利用扫描电镜(SEM)分别观察织物复合前后和材料断裂处纤维表面形态。利用高速冲击实验测试4组靶样的高速冲击性能。实验结果表明，剪切增稠行为发生在材料断裂处；剪切增稠液与无水乙醇体积比为1∶3的 STF/UHMWPE 材料高速冲击性能最好。

To explore the high-speed impact of STF composited with fabrics influenced by the dilution ratio of STF,STF was diluted by the absolute ethyl alcohol at the dilution volume ratios of 1 ∶1,1 ∶2,1 ∶3,1 ∶4. And then four groups of STF/UHMWPE material targets were prepared.Scanning electron microscope was used to observe the surface of fabrics before and after composited and watch the fibers of the broken fabric. High-speed tests were used to measure the high-speed impact property of STF/UHMWPE material targets.The results show that shear thickening behavior happens at the broken place of STF/UHMWPE materials.What’s more,the STF/UHMWPE material targets whose dilution ratio was 1 ∶ 3 have the best high-speed impact property.
