Preparation method of silicon carbide fiber reinforced silicon carbide ceramic through catalytic conversion of glass fibers
The invention discloses a method for preparing silicon carbide fiber reinforced silicon carbide ceramic by catalytically converting glass fibers, which comprises the following steps of: a, taking 60 to 80 weight percent of silicon carbide micro powder, 5 to 11 weight percent of carbon black, 8 to 16 weight percent of graphite powder, 5 to 15 weight percent of phenolic resin, 5 to 15 weight percent of glass fibers and 0.02 to 0.05 weight percent of cobalt nitrate as raw materials in parts by mass; in the application, the glass fiber is catalytically converted into the silicon carbide fiber under the action of the catalyst, the silicon carbide fiber formed by catalytic conversion retains the shape of the glass fiber, and the component of the fiber is silicon carbide and has a relatively strong combination effect with the silicon carbide ceramic. The high-temperature practicability and mechanical stability of the silicon carbide ceramic are improved. The raw materials used in the silicon carbide ceramic production process are reduced, the price of the silicon carbide fiber reinforced and toughened silicon carbide ceramic is reduced, and the method is suitable for industrial production.
本发明公开了玻璃纤维催化转化碳化硅纤维增强碳化硅陶瓷的制备方法，包括以下步骤：a.按质量份计，以60～80wt％的碳化硅微粉、5～11wt％的炭黑、8～16wt％的石墨粉、5～15wt％的酚醛树脂、5～15wt％的玻璃纤维和硝酸钴0.02‑0.05wt％为原料。本申请中，通过催化剂的作用将玻璃纤维催化转化为碳化硅纤维，催化转化而成的碳化硅纤维保留有玻璃纤维的形状，纤维的成分为碳化硅，与碳化硅陶瓷具有较强的结合作用。提高碳化硅陶瓷的高温实用性与力学稳定性。降低碳化硅陶瓷生产过程中的原料使用，降低了碳化硅纤维增强增韧碳化硅陶瓷的价格，可适用于工业生产。
