Measurement of thermal resistance of polymer sheets and fibrous layers is important in various applications including those within the engineering, ergonomics, clothing design and personal protective equipment fields. Standard methods for measurement of thermal resistance of plain materials are generally time consuming, expensive and often require the sample to be cut. Moreover, the temperature difference between the surfaces of both plates surrounding the sample must be known, as well as the sample thickness. This article describes a new measuring device named the Thermoscope. The Thermoscope is not limited by the aforementioned requirements and is able to evaluate the thermal resistance of polymer sheets and textiles by touching the sample on one surface alone. Simultaneously, the other surface is kept in thermal contact with the supporting base. The accuracy of this device was compared with the Alambeta thermal insulation tester. Effects of various base materials on measurement precision were also studied.
测量聚合物片材和纤维层的热阻在各种应用中很重要，包括工程、人体工程学、服装设计和个人防护设备等领域。测量普通材料热阻的标准方法通常耗时、昂贵，而且通常需要对样品进行切割。此外，还必须知道环绕样品的两个板的表面之间的温差以及样品的厚度。本文介绍了一种名为 Thermoscope 的新型测量装置。Thermoscope 不受上述要求的限制，只需触摸样品的一个表面即可评估聚合物片材和纺织品的热阻。同时，另一个表面与支撑底座保持热接触。该装置的准确性与 Alambeta 热绝缘测试仪进行了比较。还研究了各种基底材料对测量精度的影响。
