Abstract

ABSTRACT Active infrared thermography is one of the methods of non-destructive testing widely used in modern industry. One of the basic advantages of this particular method is its versatility – it can be used for most of the materials regardless of their physical properties. Therefore, this technique is used for non-destructive testing of the composite structures, which lately became extremely important in many industry branches. In the case of the active thermography, the needed temperature difference is usually obtained by delivering the energy to the system (i.e. heating). However, this approach is not always possible and safe for the tested materials. In this article, we suggest applying cooling to achieve a temperature difference within the tested sample. First, we will present the results of the numerical modelling of the cooling process (and cooling combined with heating) in the layered composite structures, subsequently verified in a series of experiments.

采用强制冷却的主动红外热像仪对复合材料进行数值模拟和实验评价

主动红外热像仪是现代工业中广泛应用的无损检测方法之一。这种特殊方法的一个基本优点是它的多功能性——它可以用于大多数材料，无论其物理性质如何。因此，该技术被用于复合材料结构的无损检测，这在最近的许多行业中变得非常重要。在主动热成像的情况下，通常通过向系统输送能量（即加热）来获得所需的温差。然而，对于测试材料来说，这种方法并不总是可行和安全的。在本文中，我们建议应用冷却来实现测试样品内的温差。首先，我们将介绍层状复合材料结构中冷却过程（以及冷却与加热相结合）的数值模拟结果，随后在一系列实验中进行了验证。
