The synthesis of high-temperature resistant SiC fiber membrane by centrifugal spinning

Abstract

SiC fibers have urgent application requirements under extreme conditions due to their excellent properties such as thermal stability, radiation resistance and high modulus. In this work, SiC fiber membranes with two-dimensional micro-nano fiber interwoven structures were synthesized by centrifugal spinning. TG results show that SiC fiber has good high-temperature resistance and oxidation resistance. There is no obvious damage to the SiC fiber membrane under the oxyacetylene flame heating at about 1450 °C. At heat treatment temperatures up to 2000 °C, the SiC fiber membrane still exhibits structural stability. The minimum diameter of SiC fibers is 0.7 μm. SiC fiber membranes exhibit superior mechanical and chemical stability under extreme temperature conditions. This work will help to prepare high-performance ceramic fiber membranes with different material systems.
