Thermal conduction of composites made from Kevlar^® fabric and polyurethane (PU) mineral-filled elastomers was studied. Contact heat conduction was measured according to ISO 12127 standard (which measures the threshold time required for a 10°C increase throughout the sample). PU elastomer filled with TiO₂ did not show significant differences in the threshold time for heat conduction as compared to neat PU elastomer although the values tended to be lower. The maximal threshold time was obtained for PU elastomer with TiO₂ (125 s for a sample 8 mm wide). No significant differences in the threshold time were observed for other PU elastomers with either TiO₂ filler or two added organic fire retardants. Composites made of both Kevlar^® fabric/PU and Kevlar^®/PU/Kevlar^® complied with ISO 15538:2001 standard for firefighter clothing. The aim was to determine if recycled Kevlar^® fabric could replace Nomex^®, poly(m-phenylene isophthalamide), a costly material of choice in the textile industry for firefighter structural suits.

研究了由 Kevlar ^®织物和聚氨酯 (PU) 矿物填充弹性体制成的复合材料的热传导。根据 ISO 12127 标准测量接触热传导（测量整个样品温度升高 10°C 所需的阈值时间）。与纯 PU 弹性体相比，填充有 TiO _{2 的}PU 弹性体在热传导的阈值时间方面没有表现出显着差异，尽管这些值往往较低。对于含有 TiO _{2 的}PU 弹性体，获得了最大阈值时间（8 毫米宽的样品为 125 秒）。对于具有 TiO ₂填料或两种添加的有机阻燃剂的其他 PU 弹性体，未观察到阈值时间的显着差异。由两种芳纶制成的复合材料^®面料/PU 和 Kevlar ^® /PU/Kevlar ^®符合 ISO 15538:2001 消防服标准。目的是确定回收的 Kevlar ^®织物是否可以替代 Nomex ^®聚（间苯二甲酰胺），这是纺织行业用于消防员结构服的昂贵材料。
