In this paper, optical and mechanical excitation thermography was used to investigate basalt-fiber-reinforced polymer, carbon-fiber-reinforced polymer, and basalt-carbon fiber hybrid specimens subjected to impact loading. Interestingly, two different hybrid structures including sandwich-like and intercalated stacking sequence were used. Pulsed phase thermography, principal component thermography, and partial least-squares thermography (PLST) were used to process the thermographic data. X-ray computed tomography was used for validation. In addition, signal-to-noise ratio analysis was used as a means of quantitatively comparing the thermographic results. Of particular interest, the depth information linked to Loadings in PLST was estimated for the first time. Finally, a reference was provided for taking advantage of different hybrids in view of special industrial applications.

用于玄武岩-碳混合纤维增强复合材料层压板冲击响应的光学和机械激发热成像


在本文中，采用光学和机械激发热成像技术研究了承受冲击载荷的玄武岩纤维增强聚合物、碳纤维增强聚合物和玄武岩碳纤维混合样品。有趣的是，使用了两种不同的混合结构，包括三明治状和插层堆叠顺序。使用脉冲相位热成像、主成分热成像和部分最小二乘热成像（PLST）来处理热成像数据。 X 射线计算机断层扫描用于验证。此外，信噪比分析被用作定量比较热成像结果的手段。特别有趣的是，首次估计了与 PLST 中的载荷相关的深度信息。最后，为特殊工业应用中不同混合方式的利用提供参考。
