摘要
提出一种采用埋入式光纤传感器无损检测复合材料结构状态的新方法。将两种结构简单的新颖光纤传感网络埋入飞机的层状复合材料垂直尾翼试件 ,对结构内应变、应力以及由于外部冲击造成的损伤等状态参数进行检测 。
A novel nondestructive testing method for the structural state of composite with optical fiber sensors was presented. Two types of simple fiber optic sensor networks embedded in the laminated composite material structures of vertical tail wing of plane were used to test the strain, stress and the damage caused by external impact. Experimental results showed the feasibility of the method.
