摘要

为提高防护服的热防护性能，设计了形状记忆合金(SMA)弹簧在4种不同变形高度和5种排列方式下的温度响应防护面料。在0.39 cal/cm2 s的辐射热暴露条件下，研究了其热防护性能。结果表明，SMA弹簧在织物层间产生气隙，有效提高了织物的防护性能。不同排列方式和尺寸的织物的热防护性能表现出不同的趋势，并分析了排列方式和尺寸的交互作用。提出了SMA弹簧的优化布置和尺寸。建立回归模型，评估气隙与热防护之间的关系。该研究表明，将阻燃织物与SMA结合开发温度响应防护服是可行的，因为它可以通过产生响应环境变化的智能气隙来提高隔热性能。

On the Effectiveness of Temperature-Responsive Protective Fabric Incorporated With Shape Memory Alloy (SMA) Under Radiant Heat Exposure

To improve thermal protection of protective clothing, temperature-responsive protective fabrics incorporated with shape memory alloy (SMA) springs varying on four different deformation heights and five types arrangement modes were designed. The thermal protection was investigated under radiant heat exposure of 0.39 cal/cm2 s. The results indicated that the air gap between fabric layers produced by SMA springs effectively improved protective performance. The thermal protection of fabrics with different SAM arrangement modes and sizes showed different trends, and the interaction effects of arrangement mode and size were analyzed. Moreover, the optimized arrangement and size of SMA springs were suggested. The regression models were established to assess the relationship between the air gap and thermal protection. This study demonstrated that the combination of flame-resistant fabric with SMA was feasible to develop temperature-responsive protective clothing because it could improve thermal insulating property by producing intelligent air gaps that responded to environment change.
