| 摘 要： | 高性能SiC纤维在耐高温、抗氧化领域有着重要的应用前景,而纤维直径是影响纤维力学性能的主要因素之一。随着纤维直径降低,纤维强度显著升高。利用静电纺丝工艺,结合先驱体热解转化法制备SiC,探索了一种简单、易行的制备亚微米/纳米SiC纤维的方法。由聚碳硅烷(PCS)出发,研究了PCS溶液静电纺丝的工艺参数对纺丝性的影响,PCS原纤维经不熔化、N2中1200℃热处理1h,成功的制备了纤维直径在0.5原2μm之间分布均匀的SiC纤维。 |

| Abstract: | High performace SiC fibers have many promoting applications in the high temperature and oxidation resistance environment and the diameter of fiber is one of the main influence factors on the mechanical properties, especially, the tensile strength increases evidently with the diameter decreases. Combining with the polymer-derived ceramic method, an easy and feasible method has been developed to produce the sub-micro/nano SiC fibers by electrospinning. Started from polycarbosilicon (PCS), the main parameters which affected the electrospinning spinnability were studied and the sub-micro/nano SiC fibers with the diameter of 0.5～2 μm were produced successfully after curing and heat treatment of PCS green fibers in N_2 at 1200 ℃ for 1h. |
