佛罗里达农工大学-佛罗里达州立大学的 PI 提出了一种由内部微线构建的摩擦发光传感机制（物理故障发光），用于检测复合材料中的多尺度损伤。摩擦发光机制用于连续微型传感器（μ传感器），该微型传感器包含纳米级增强元件，可创建结构电子设备。本文讨论了摩擦发光传感器机制和阵列的微检测能力。一种称为“溶液成型”的技术是使用商业可溶性化合物进行 3D 打印，以满足所需的尺寸和几何形状，包括对整个结构或拼接组件进行负拔模的复合处理。原位摩擦发光光纤（μ传感器）以其商品名嵌入纤维增强结构复合材料中以提供传感系统。对 12 块 GF 面板进行了冲击损伤测试，并报告了检测微损伤的传感系统的性能。小于 6.5 cm2 的阵列尺寸能够检测低速冲击损伤。进行分段和连接分析以验证所提出的感觉系统响应的准确性。号码：10.12783/SHM2015/217
The PI’s at Florida A&M University-Florida State University, propose a triboluminescent sensory mechanism (physical failure-to-luminescence) constructed from in-house micro-wires to detect multiscale damage in composites. Triboluminescence mechanisms are utilized in a continuous micro sensor (μ-sensor) that contain elements of nanoscale reinforcement to create a structural-electronic device. This paper discusses micro-detection capabilities of the triboluminescent sensor mechanism and array. A technique known as “Solu-Molding” is 3D printed using a commercial soluble compound to meet the desired dimensions and geometry, including composite processing for negative draft of an entire structures or spliced component. In-situ Triboluminescent Optical Fiber (μ-sensors), by its trade name, are embedded in fiber reinforced structural composites to provide a sensory system. 12 GF panels were tested for impact damage and performance of the sensory system to detect micro-damage is reported. An array size of less than 6.5 cm2 was able to detect low-velocity impact damage. Segmental and junction analysis was performed to verify the accuracy of the proposed sensory system response. doi: 10.12783/SHM2015/217
