Characterization of Fracture and Fatigue Behaviors of Next Generation Thermally Active Composite Materials and their Performance and Lifetime Enhancements

为了提高新一代热活性复合材料的性能和寿命，我们对其断裂和疲劳行为进行了研究。我们从理论和实验两个方面表征了热活性复合材料在弯曲载荷下的断裂、变形和疲劳行为。此外，我们还考察了碳纳米管(CNT)的加入对聚合物材料的断裂和疲劳行为以及碳纳米管基聚合物复合材料的变形/损伤传感能力的影响，为高性能和长寿命复合材料的开发提供了有益的结果。

We investigated the fracture and fatigue behaviors of next generation thermally active composite materials in order to improve their performance and lifetime. We characterized both theoretically and experimentally the fracture, deformation and fatigue behaviors of thermally active composites under flexural loading. Also, we examined the effect of carbon nanotube (CNT) addition on the fracture and fatigue behaviors of polymeric materials and the deformation/damage sensing ability of CNT-based polymer composites, and obtained the beneficial results for the development of high performance and long life composite materials.
