引入＂复配＂的概念,制备出不同复配方式的剪切增稠液体（STF）,并将该复配型STF对超高分子量无纺布进行处理,通过对STF无纺布的复合材料进行扫描电镜形貌分析以及静态防刺实验,来对复合织物的防刺性能进行研究。主要阐述了不同分子量分散介质（PEG200、PEG600）复配后的剪切增稠液与无纺布织物复合后对复合材料防刺性能的影响,发现采用不同分子量分散介质较单一分子量分散介质的STF无纺布复合织物的防刺性能好,采用复配分散介质的方式对剪切增稠液体在防刺效果上有一定程度的改善作用,在同等单位质量的情况下,此复配方式可将复合材料的防刺性能提高7.13%。
By introducing the idea of "complex match",shear thickening fluid(STF) was prepared in several kinds and the different kinds of STF were compound with ultra high molecular weight polyethylene non-woven fabrics.The pattern and performance of the compound fabric were characterized by scanning electron microscopy(SEM) and static stab resistant experiment.The paper mainly studied the impact in stab-resistant performance of the non-woven fabrics which were treated by complex STF with different molecular weight(PEG200,PEG600).It can be found that the performance of treated fabric with different molecular weight dispersed media is better than the one with single molecular weight.It also shows that the complex STF could improve the performance of stab resistance to a certain extent.The penetration strength was enhanced by 7.13% with the same unit mass in this paper.
