该研究涉及 CFRP 层压复合材料的疲劳寿命与疲劳测试期间获得的热分析信息之间的相关性。这项研究是针对两种不同的层压顺序和三种不同的加载频率进行的。还通过刚度降低和磁滞回线面积增加测量来评估损坏进展。在前几个负载循环中评估的热能（以热量形式耗散的机械能）被发现是预测疲劳寿命的良好参数。
The research dealt with the correlation between fatigue life of a CFRP laminate composite and the thermal analysis information obtained during the fatigue tests. This study was done for two different lamination sequences and three different loading frequencies. The damage progression was also evaluated by stiffness reduction and hysteresis loop areas increase measurements. The thermal energy, which is the amount of mechanical energy dissipated in the form of heat, evaluated in the first few load cycles was found to be a good parameter to predict fatigue life.
