防火衣における高熱伝導素材を用いた局所温度上昇の緩和

抄録

Previous experiments with mannequins have shown that when a fire suit is exposed to flame, the temperature rise between the fire suit and the body surface is not uniform. This localized temperature rise can cause severe burns. Therefore, the purpose of this study is to develop a composite material that can mitigate the local temperature rise and slow heat transfer. As a method, we propose to create a layer of high thermal conductivity inside the composite material of the fireproof clothing to spread the incoming heat over a wider area and mitigate the temperature rise. Experiments were conducted in which a copper layer was added to a sample of current fireproof clothing and heated by conduction and radiation, respectively. The results showed that the temperature rise was mitigated under both heating conditions, and the amount of mitigation increased with an increase in heat flux.
