In this article, the goal is to monitor the deformation and damage behavior of composites in real-time using a Nylon/Ag fiber sensor when subjected to dynamic loading. Composite samples are integrated with Nylon/Ag fiber sensors at distinct locations and directions between the plies. Then, these samples are experimentally impacted with low-velocity impact using the Taylor Cannon Gun apparatus at three different velocities i.e. 2.5 m s −1 , 3 m s −1 , and 6.5 m s −1 , respectively. These three sets of tests are conducted to determine the detection performance of the Nylon/Ag fiber sensor when the composite sample experiences no damage, some microdamage, and overall breakage. Besides, the fiber sensor placed in each position showed distinct electrical behavior in all three tests and detected the deformation, damage initiation, quantification, identification, and damage propagation. The results confirmed the ability of the fiber sensor to monitor and iden...

尼龙/银纤维传感器，用于动态载荷下复合材料的实时损伤监测

在本文中，目标是在动态载荷下使用尼龙/银纤维传感器实时监测复合材料的变形和损坏行为。复合样品在两个层之间的不同位置和方向上与尼龙/银纤维传感器集成在一起。然后，使用泰勒·坎农枪装置以三种不同的速度，即分别为2.5 ms -1，3 ms -1和6.5 ms -1对这些样品进行低速冲击实验。进行这三组测试以确定复合材料样品没有损坏，有些微损伤和整体断裂时尼龙/银纤维传感器的检测性能。此外，放置在每个位置的光纤传感器在所有三个测试中均显示出不同的电性能，并检测出变形，损坏的开始，量化，识别和损害传播。结果证实了光纤传感器具有监视和识别光纤的能力。
