This research focused on fracture and fatigue response of carbon/epoxy laminates modified with electrospun nylon 66 nanofibers. For this purpose, AS4/8552 composite laminates interleaved by nanofibrous mat were considered under mode-I quasi-static and fatigue loading conditions. According to test outcomes, the fracture toughness increased about 133% under quasi-static tests. On the other hand, the plotted fatigue curves showed that the crack growth rate significantly decreased in modified samples and the threshold energy release rate enhanced about 128%. Finally, scanning electron microscopy (SEM) was also conducted to investigate the damage mechanisms.

这项研究的重点是用电纺尼龙66纳米纤维改性的碳/环氧层压板的断裂和疲劳响应。为此，考虑了在模式I准静态和疲劳载荷条件下，被纳米纤维毡交错的AS4 / 8552复合层压板。根据测试结果，在准静态测试下，断裂韧性提高了约133％。另一方面，绘制的疲劳曲线表明，改性样品的裂纹扩展速率显着降低，阈值能量释放速率提高了约128％。最后，还进行了扫描电子显微镜（SEM）研究其损伤机理。
