摘　　要：为进一步提高消防服用蜂窝织物的热防护性能,针对隔热层进行蜂窝孔型的结构优化与测评。选取当前典型的消防服各层材料,综合考虑隔热层分层和蜂窝孔型的边长、壁厚等因素,分别对直孔和斜孔设计了6种孔洞尺寸以及1种实心对照组。利用激光切割技术进行13组实验方案制备试样,并采用热防护性能测试仪进行闪火燃烧测试。实验结果表明:蜂窝分层重组可有效提高消防服用蜂窝织物系统的热防护性能;通过非参数相关样本检验,测得不同开孔方式蜂窝织物的热防护性能有着显著性差异,说明斜孔结构比直孔具有更好的热防护性。In order to improve the thermal protective performance of honeycomb fabric for firefighter protective clothing,the honeycomb hole structure optimization and evaluation were carried out for the thermal barrier.The current typical fabrics of firefighter protective clothing were chosen as the experimental samples.Considering thermal liner layering,honeycomb side length and wall thickness,six kinds of hole sizes were designed for the straight holes and the inclined holes respectively,and a solid control group was presented.Then 13 sets of experimental schemes were prepared by laser cutting technology and a thermal protective performance tester was adopted to perform the flash fire test.The experimental results show that honeycomb layering reorganization effectively improves the thermal protective performance of honeycomb fabric systems for firefighter protective clothing.By the non-parametric correlation sample test,a significant difference exists in the thermal protective performance of the honeycomb sandwich structure with different opening methods,and the inclined hole structure has better thermal protective performance than the straight hole.
