Electrospinning is a process in which solid fibers are prepared from polymer solution. In recent decades, studies have focused on improving the properties of electrospun nanofibers by exploring the possibilities of electrospinning different polymers. Two critical properties that have been studied in relation to this technique are thermal stability and mechanical properties. In this study, polyamide-6 (PA-6) nanofibers were prepared by embedding combinations of alumina and tungsten carbide particles. The morphology of the resulting hybrid nanofibers was analyzed using scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX), differential scanning calorimetry (DSC) and Thermogravimetric (TGA) techniques, and tensile tests were performed to evaluate their mechanical properties. The results showed that the sample containing tungsten carbide with a weight ratio of 4:10 had the highest melting standard enthalpy. The analysis also revealed that hybrid fibers containing equal ratios of alumina and tungsten carbide, each with a weight ratio of 2:10, had higher degradation temperatures and melting enthalpy compared to other nanofibers. Tensile testing showed that nanofibrous mats containing tungsten carbide had higher Young’s modulus, PA-6 fibers.

静电纺丝是由聚合物溶液制备固体纤维的过程。近几十年来，研究重点是通过探索静电纺丝不同聚合物的可能性来提高静电纺纳米纤维的性能。与该技术相关的两个关键特性是热稳定性和机械特性。在这项研究中，通过嵌入氧化铝和碳化钨颗粒的组合来制备聚酰胺-6 (PA-6) 纳米纤维。使用扫描电子显微镜（SEM）、场发射扫描电子显微镜（FESEM）、能量色散X射线光谱（EDX）、差示扫描量热法（DSC）和热重分析（TGA）技术分析所得混合纳米纤维的形态，并进行拉伸测试以评估其机械性能。结果表明，含有重量比为4:10的碳化钨的样品具有最高的熔化标准焓。分析还表明，与其他纳米纤维相比，含有等比例氧化铝和碳化钨（重量比为2:10）的混合纤维具有更高的降解温度和熔化热函。拉伸测试表明，含有碳化钨的纳米纤维垫具有更高的杨氏模量，PA-6 纤维。
