摘　　要：选用具有长、直形貌的陶瓷基纳米纤维即碳化硅纳米线(SiCNW)作为增强体,通过对SiCNW含量的优化与电纺液的制备,研究SiCNW的引入对电纺纤维结构和性能的影响,并分析其增强机理。SiCNW是纳米级别的陶瓷纤维,具有优异的力学、热学和抗氧化等性能,其作为增强相在金属、陶瓷等复合材料方面已经取得了一些成果,特别是在聚合物基复合材料的应用研究中取得丰硕的成果。实验结果表明:SiCNW的加入可有效强化电纺纤维,使其强度最大可提高约30%,SiCNW的强化机制为SiCNW的桥接和断裂。The long and straight morphology of ceramic nano fibers named SiC nanowires（SiCNW） were chosen as reinforcement to improve the comprehensive properties of the electrospinning nano-fibers. The influences of SiCNW on the structure and properties of electrospinning fibers were studied through the optimization of SiCNW contents and the preparation of electrospinning solution. The enhancement mechanism was analyzed. SiCNW was nanoscale ceramic fiber with excellent mechanical, thermal and anti-oxidation properties. Experimental results showed that the addition of SiCNW could strengthen the electro-spinning nano-fibers, and the intensi- ty was improved 30%. The strengthening mechanism of SiCNW was the bridging and fracture.
