The latest directions of research on the design of protective clothing concern the implementation of smart materials, in order to increase its protective performance. This paper presents results on the resistance to thermal factors such as flames, radiant heat, and molten metals, which were obtained for the developed smart textile material with shape memory alloys (SMAs). The laboratory tests performed indicated that the application of the designed SMA elements in the selected textile material system caused more than a twofold increase in the resistance to radiant heat (RHTI = 224 s) with an increase of thickness of 13 mm (sample located vertically with a load), while in the case of tests on the resistance to flames, it was equal to 41 mm (sample located vertically without a load) and in the case of tests on the resistance to molten metal, it was 17 mm (sample located horizontally).
防护服设计的最新研究方向涉及智能材料的应用，以提高其防护性能。本文介绍了对具有形状记忆合金（SMA）的新型智能纺织材料进行的诸如火焰、辐射热和熔融金属等热因素抗性测试结果。实验室测试表明，在选定的纺织材料系统中应用设计的SMA元件，在厚度增加13毫米（垂直放置有负载的样品）时，对辐射热的抗性提高了两倍多（RHTI = 224秒），而在火焰抗性测试中，该厚度为41毫米（垂直放置无负载的样品），在熔融金属抗性测试中，该厚度为17毫米（水平放置的样品）。
