Abstract Carbon Fiber Reinforced Polymer (CFRP) composite materials have been widely used in high-tech fields because of their outstanding physical properties. However, barely visible impact damage can be introduced by low velocity impact, which might bring tremendous risk. Monitoring impact forces is essential for the integrity and reliability of CFRP structures. In this paper, a reverse localization scheme on CFRP composite materials is developed. The scheme is based on a predictive mode of attenuated strain wave. The signals induced by low velocity impact are obtained by strain gauges. The proposed localization scheme has been verified by experimental tests of the CFRP plates with symmetrical stacking [0/45/90/−45]2s The errors occurring in the test can be accepted for engineering application. The calculated impact locations are generally in consistent with the testing impact locations.

使用衰减应变波对复合材料层压板进行反向定位

摘要 碳纤维增强聚合物（CFRP）复合材料以其优异的物理性能在高科技领域得到了广泛的应用。然而，低速撞击可能会引入几乎不可见的撞击损坏，这可能会带来巨大的风险。监测冲击力对于 CFRP 结构的完整性和可靠性至关重要。在本文中，开发了 CFRP 复合材料的反向定位方案。该方案基于衰减应变波的预测模式。由低速冲击引起的信号由应变仪获得。所提出的定位方案已经通过对称堆叠的CFRP板的实验测试得到验证[0/45/90/-45]2s，测试中出现的误差可以接受工程应用。
