摘要
本文利用低速冲击装置冲击四周简支复合材料板试样,用以模拟低速低能量冲击而造成的分层损伤;用中心钻孔复合材料板试样用以模拟因高速冲击而造成穿透性损伤。探讨利用内埋康铜电阻丝阵列构成检测网络实现对复合材料中损伤位置和损伤程度检测。这种方法可利用较成熟的电测技术,装置简单。
The technique of damage detecting for laminates by embedded array of resistance wires is presented. It is demonstrated by experiments on laminates subjected to low speed impacts (which may cause delaminations), or experiments on laminates subjected to punching (which may simulate penetrating failure under high speed impacts). Locations and/or degrees of damages are detected with relatively simple devices.
