| titleOfInvention | A kind of preparation method of the continuous SiC fiber that resistivity can be on a large scale regulated and controled |
| abstract | A kind of preparation method of the continuous SiC fiber that can on a large scale regulate and control to resistivity, comprises the following steps：（1）SiC ceramic precursor is carried out into drawing-off spinning, fibrillation is obtained；（2）Fibrillation is placed in cure treatment device, is vacuumized, then fill inert atmosphere, after repeating aforesaid operations >=2 time, gel content >=85% of fiber is made by electron beam irradiation crosslinking or reactive atmosphere crosslinking, obtain fusion-free fibre；（3）Fusion-free fibre is placed in high temperature furnace, the gaseous mixture of inert atmosphere or reactive atmosphere and inert atmosphere is passed through, 1000~1600 DEG C are warming up to the speed of 60~200 DEG C/h, be incubated 0.5~2.0h, obtain continuous SiC fiber.The inventive method can as needed be obtained resistivity 10 ‑1 ~10 6 Ω cm adjustable continuous SiC fibers on a large scale, average diameter is uniform, and mechanical property is good；The inventive method process is simple, it is easy to accomplish industrialized production, low cost. |
