摘 要：武术运动中有许多项目需运用锐器，会对人体安全造成一定的威胁。基于此，为得到防刺性能更加优异的武术运动复合防刺材料，制备了聚氨酯（C3H8N2O）芳纶平纹织物武术运动复合防刺材料，研究了不同种类的C3H8N2O、不同涂层工艺和叠加结构的C3H8N2O芳纶平纹织物武术运动复合防刺材料对防刺性能的影响。结果表明：Base cloth的防刺性能较C3H8N2O复合芳纶布的防刺性能更优;常规的聚酯型C3H8N2O和聚醚型C3H8N2O与聚碳酸酯型C3H8N2O复合材料的撕裂性能与防刺性能相比较差;组成组分相同的、叠加结构不同的织物其防刺性能不同。

Abstract：Many events in martial arts require the use of sharps， which will pose a certain threat to human safety. Based on this， in order to obtain a martial arts composite stab-resistant material with better stab resistance， a polyurethane （C3H8N2O） aramid plain weave fabric martial arts composite stab-resistant material was prepared. The effects of different types of C3H8N2O， C3H8N2O aramid plain weave fabrics with different coating processes and superimposed structures on martial arts sports composite stab-resistant materials were studie.The results show that the stabbing performance of Base cloth is better than that of C3H8N2O composite arylon cloth. The conventional polyester type C3H8N2O and polyether type C3H8N2O and polycarbonate type C3H8N2O composites have poor tearing and stabbing performance. The stings resistance of fabrics with the same composition and different superposition structure is different.
