摘　　要：对纳米SiC进行表面有机化改性处理后,采用凝胶纺丝法制备了纳米SiC/超高分子量聚乙烯复合纤维。通过FT-IR、沉降试验、激光粒度分析仪,分析了纳米SiC的表面有机化改性效果,然后利用WAXD、力学性能测试、DSC、TGA等测试方法,对复合纤维的结构及性能进行了表征分析。结果表明:分散良好的纳米SiC复合纤维的力学性能得到了提升,耐热性也得到改善。Nano-sized SiC/ultra-high molecular weight polyethylene （UHMWPE） composite fiber was prepared through gel spinning. The surface modification effectiveness of nano-sized SiC was observed and analyzed by FT-IR, settlement test and laser particle size analyzer. The properties of the composite fiber was characterized using WAXD, DSC, mechanics performance testing and TGA. The experiment result showed that the performances as the mechanics, thermal stability of the SiC/UHMWPE composite fiber had been much improved.
