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
