This is a study of the possibilities of a qualitative evaluation of protective materials with active thermography. It presents a simulation of a periodic excitation of a multilayer composite material. Tests were conducted with lock-in thermography on Kevlar composite consisting of 16 layers of Kevlar fabric reinforced with formaldehyde resin with implanted delamination defects. Lock-in thermography is a versatile tool for nondestructive evaluation. It is a fast, remote and nondestructive procedure. Hence, it was used to detect delaminations in the composite structure of materials used in the production of components designed for personal protection. This method directly contributes to an improvement in safety.
这是一项关于使用主动热成像技术对防护材料进行定性评估的可能性的研究。本文介绍了对多层复合材料进行周期性激励的模拟。使用锁相热成像技术对由 16 层芳纶织物增强甲醛树脂组成的芳纶复合材料进行了测试，该复合材料中植入了分层缺陷。锁相热成像技术是一种多功能的无损评估工具。它是一种快速、远程和非破坏性的程序。因此，它被用于检测用于个人防护组件生产的材料的复合材料结构中的分层。这种方法直接有助于提高安全性。
