采用疲劳寿命计对复合材料层板的疲劳过程进行了监测，研究了复合材料层板在单级和多级载荷下的疲劳累积损伤与疲劳寿命计电阻变化之间的关系。结果表明疲劳寿命计的输出电阻的累积变化能较好地反映层板的疲劳状态。
The fatigue life of composite laminates was monitored by fatigue life meter. The relationship between fatigue cumulative damage of composite laminates under single and multistage loads and resistance change of fatigue life gauge was investigated. The results show that the cumulative change of the output resistance of the fatigue life meter can better reflect the fatigue state of the laminates.
