| titleOfInvention | A kind of method being prepared silicon carbide fiber by high softening-point Polycarbosilane |
| abstract | A kind of method being prepared silicon carbide fiber by high softening-point Polycarbosilane, comprise the following steps: low-molecular-weight polycarbosilane mixes with the organosilane containing vinyl or silicon nitrogen silane compound by (1), by Si―H addition reaction catalytic thermal polyreaction or by spinning-grade Polycarbosilane precipitation fractionation, obtain high softening-point Polycarbosilane; (2) high softening-point Polycarbosilane is carried out melt-spinning, obtain continuous polycarbosilane fiber; (3) continuous polycarbosilane fiber is placed in non-oxygen reactive atmosphere and carries out cure treatment, obtain Polycarbosilane fusion-free fibre; (4) Polycarbosilane fusion-free fibre is carried out high temperature burn till or after pyrolysis decarburization again high temperature burn till, obtain low oxygen content or Near-stoichiometric SiC fiber.The inventive method technique is simple, invests little, low cost of manufacture, is suitable for industrial mass preparation; Gained low oxygen content silicon carbide fiber oxygen level≤1.2wt%, Near-stoichiometric SiC fiber C/Si is 1 ~ 1.07, good mechanical performance. |
