Fiber-reinforced polymer matrix composites are widely used in many structural applications thanks to their exceptional properties. In recent years, the use of electrospinning nanofibers with unique properties as reinforcement agents has attracted a great deal of attention in improving the performance of these composites. Although there are many promising studies on this subject in the literature, there are still many issues that need to be investigated. In this study, an experimental research reporting on the production and mechanical properties of two-phase polymer matrix composites reinforced with various types of thermoplastic nanofibers is presented. Nanofiber mats were produced from N66, PAN, PVA, and PVC polymers by electrospinning technique. Composites were obtained by embedding these nanofibers into epoxy resin by using vacuum infusion process. Mechanical properties of the composites were determined by performing tensile tests and the results were compared. The morphologies of nanofibers and the fracture surfaces of the composites were examined with SEM. Finally, statistical evaluations were carried out using mechanical data. According to tensile test results, the best ultimate tensile strength of 38.04 ± 3.7 MPa, elongation of 2.46 ± 0.4 % and toughness of 532 ± 137 kJ/m³ were obtained from N66 nanofiber composite, while PVA nanofiber composite was the most favorable in terms of Young's modulus (2.40 GPa). It was observed that the polymer type significantly affected the performance of the composite. In addition to the best mechanical properties, N66 composite was found to be more stable and reproducible than other specimens. Due to the good impregnation of nanofibers, it was conclusively determined that the use of vacuum infusion process is suitable for the production of these materials.

纤维增强的聚合物基复合材料由于其优异的性能而广泛用于许多结构应用中。近年来，具有独特性能的静电纺丝纳米纤维作为增强剂的使用在改善这些复合材料的性能方面引起了极大的关注。尽管在文献中有许多关于该主题的有前途的研究，但是仍然有许多问题需要调查。在这项研究中，提供了有关用各种类型的热塑性纳米纤维增强的两相聚合物基复合材料的生产和力学性能的实验研究报告。纳米纤维垫是由N66，PAN，PVA和PVC聚合物通过静电纺丝技术制成的。通过使用真空灌注工艺将这些纳米纤维嵌入环氧树脂中来获得复合材料。通过进行拉伸试验确定复合材料的机械性能，并比较结果。用SEM检查纳米纤维的形态和复合材料的断裂表面。最后，使用机械数据进行统计评估。根据拉伸试验结果，最佳极限抗拉强度为38.04±3.7 MPa，伸长率为2.46±0.4％，韧性为532±137 kJ / m从N66纳米纤维复合材料获得^3种，而就杨氏模量（2.40 GPa）而言，PVA纳米纤维复合材料是最有利的。观察到聚合物类型显着影响复合材料的性能。除了最佳的机械性能，N66复合材料还比其他样品更稳定和可重现。由于纳米纤维的良好浸渍，因此最终确定使用真空灌注工艺适合生产这些材料。
