摘要：

为改善当前热防护服普遍存在的笨重、闷热问题,针对隔热层进行蜂窝结构设计,并对整体热防护服用织物进行辐射热性能的测评。选取当前典型的热防护服用面料,综合考虑外层材料、蜂窝芯厚、边长、壁厚等影响因素,采用正交试验方法设计了32种试验方案,通过激光切割技术进行试样制备,并利用辐射热防护性能测试仪进行测评。实验结果表明:蜂窝夹芯结构可以明显减轻隔热层的质量;外层织物为PBI^?matrix的试样比Nomex^?IIIA试样具有更好的辐射热防护性能。同时,根据极差分析得出:影响蜂窝夹芯结构的辐射热性能的因素主要是蜂窝芯厚,其次是壁厚,影响最小的是边长;且芯厚越大,边长越小,壁厚越大,蜂窝夹芯层的辐射热防护性能越好。

Abstract:

In order to solve the bulky and sultry problem of current thermal protective clothing, a honeycomb structure for the heat insulation layer was designed, and the radiation thermal performance of the overall thermal protective clothing fabric was evaluated. In the experiment, the typical current thermal protection fabric was selected, the outer material, honeycomb core thickness, side length, wall thickness and other influencing factors were taken into account comprehensively. The 32 kinds of experimental schemes were designed by orthogonal experiment method, the sample was prepared by laser cutting technology, and the radiant protective performace(RPP) value was evaluated by the radiation thermal protection performance tester. The results show that the honeycomb sandwich structure can significantly reduce the weight of the insulation layer. The outer fabric for PBI^? matrix sample has better heat protective performance than Nomex^? IIIA sample. At the same time, according to the range analysis, the main factors affecting the radiative heat performance of honeycomb sandwich structure are the thickness of honeycomb core, the second is the wall thickness, and the least is the side length. The larger the core thickness, the smaller the side length, the larger the wall thickness, and the better the radiative heat protection performance of honeycomb sandwich.

Key words: thermal protective clothing, honeycomb sandwich structure, radiation heat, core thickness
