摘　　要：[研究方法]以400 D超高分子量聚乙烯(UHMWPE)纤维为原料,采用不同比例的纳米二氧化锆/聚氨酯(ZrO2/PU)通过非溶剂致相转变法对纤维进行涂层处理。采用扫描电镜、红外光谱、力学性能和微球脱粘对复合纱线的微观结构和力学性能进行了表征。[研究结果与结论]结果表明:纳米ZrO2/PU复合材料能够良好的包覆纤维;复合纱线的线密度和表面粗糙度随着纳米ZrO2含量的增加而增加;复合纱线的拉伸强力随着纳米ZrO2含量的增加而增加;纳米二氧化锆的添加有利于提高复合材料与UHMWPE纤维间的界面作用力。The 400 D ultra-high molecular weight polyethylene(UHMWPE) fibers were coated with different concentrations of nano ZrO2 particles/polyurethane(ZrO2/PU) using non-solvent induced phase separation method. The microstructure and mechanical properties of composite yarns were investigated by scanning electron microscope, Fourier transform infrared spectroscopy, mechanical properties and micro-debonding. The results showed that the UHMWPE fiber were tightly packed by nano ZrO2/PU composites;the linear density and surface roughness of the composite yarns were increased with the increase of the nano ZrO2 content. Furthermore, the tensile strength of UHMWPE composite yarn was increased when increasing the nano ZrO2 content. Moreover, micro-debonding analysis confirmed that the incorporation of nano ZrO2 could improve the the interfacial force between the composite and UHMWPE fibers.
