Evaluation of thermal storage performance of honeycomb insulation layer for fireproof clothing

In order to improve the stored thermal energy of fireproof clothing in the fire environment, the honeycomb insulation layer was applied to the fireproof clothing, and its heat storage performance was evaluated. The current typical fire-fighting clothing fabrics was selected, the side length, wall thickness and core thickness of the honeycomb core were designed, and 21 kinds of experimental samples were prepared. The fire environment was simulated by the stored energy test instrument, and the minimum exposure time(MET) of the experimental samples was recorded. The influences of the length, wall thickness and core thickness of the 6 honeycomb types on MET of the experimental samples were investigated. The results show that the weight of the thermal liner can be reduced by up to 64%, and the MET is increased by up to 10 s. As the wall thickness of the honeycomb hole type increases, the MET also increases. The core thickness is positively correlated with the MET, and the side length of the hole is negatively correlated with the MET.
