Abstract

This paper presents a new method for evaluating the failure and processing technology of fiber-winding composites based on infrared thermography. Firstly, infrared thermography was used to monitor the surface temperature evolution during the loading of Naval Ordnance Laboratory (NOL) rings. Secondly, the mechanical and temperature data were recorded simultaneously until the failure of the NOL rings occurred. Thirdly, the mechanical results were compared with the monitoring results obtained from infrared thermography concerning the failure of the NOL rings. Lastly, an evaluation was conducted regarding the capability of infrared thermography to elucidate the failure of the NOL rings. The experiment results demonstrated that infrared thermography can characterize the failure process and failure modes of fiber-winding composites with limited mechanical or optical technology. Besides, this testing technology provides a significant advantage when comparing fiber volume fractions, particularly in situations where professional testing devices are unavailable. This work provides a new reference for the application of infrared thermography within the domain of fiber-winding composites.

基于红外热成像技术评估 NOL 环的拉伸破坏过程

本文介绍了一种基于红外热成像技术评估纤维缠绕复合材料失效和加工技术的新方法。首先，使用红外热成像技术监测海军军械实验室（NOL）环在加载过程中的表面温度变化。其次，同时记录机械和温度数据，直至 NOL 环发生故障。第三，将机械结果与红外热成像对 NOL 卡环失效的监测结果进行比较。最后，对红外热成像技术阐明 NOL 环失效的能力进行了评估。实验结果表明，红外热成像技术可以利用有限的机械或光学技术表征纤维缠绕复合材料的失效过程和失效模式。此外，在比较纤维体积分数时，尤其是在没有专业测试设备的情况下，这种测试技术具有显著优势。这项工作为红外热成像技术在纤维缠绕复合材料领域的应用提供了新的参考。

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
