摘　　要：剪切增稠胶(STG)是一种新型功能材料,通过流变测试研究了STG的稳态流变性能及其剪切增稠的作用方式。将STG与超高分子量聚乙烯(UHMWPE)织物复合制备了STG/UHMWPE复合材料,利用扫描电子显微镜对复合前后材料的形貌进行分析,并研究了复合材料的低速冲击性能。结果表明:加入STG后,STG/UHMWPE复合材料的剩余冲击载荷可减少50%;在不同冲击速度条件下,复合材料能量吸收系数均超过80%。STG具有优异的力学性能,通过与UHMWPE织物复合可显著提高复合材料的抗冲击性能。Shear thickening glue(STG)is a new functional material.The steady rheological properties of STG and the mode of shear thickening were studied by steady state rheological testing.STG/UHMWPE composites were prepared by combining STG with UHMWPE fabrics.Scanning electron microscope was used to analyze the morphology of the composites,the low velocity impact properties of the composites were investigated.The results shown that the residual impact load of STG/UHMWPE can be reduced by 50% after adding STG.The energy absorption coefficient of composites exceeded 80% under different impact velocity.STG had excellent mechanical properties and can significantly improve the impact resistance of composites by combining with UHMWPE fabrics.
