Impregnation device and method for preparing fiber-reinforced precursor converted ceramic matrix composite material by using impregnation device
The invention discloses a dipping device and a method for preparing a fiber-reinforced precursor converted ceramic matrix composite by using the dipping device, the method comprises the dipping device, and the method comprises the following steps: S1, preparing fibers into a prefabricated part; s2, the prefabricated part is soaked, specifically, the prefabricated part is put into a soaking device, air in a vacuum bag is exhausted through a vacuumizing device, a precursor enters the soaking device, and the prefabricated part is soaked; and S3, the prefabricated part is cured, specifically, the vacuum bag and all the structures in the vacuum bag are put into a drying oven together, and the drying oven is used for heating. S4, the prefabricated part is sintered, specifically, the prefabricated part is put into a cracking furnace to be sintered, and in the sintering process, the cracking furnace is filled with argon and exhausted; and S5, repeating the steps S2-S4 for a plurality of times, and taking out the prefabricated part from the cracking furnace to obtain the ceramic-based fiber composite material. The method can be used for preparing the prefabricated part with a complex shape, the impregnation effect is improved, the porosity of a final finished product is reduced, the compactness is increased, and the performance is improved.
本发明公开了一种浸渍装置、使用浸渍装置制备纤维增强先驱体转化陶瓷基复合材料的方法,方法包括浸渍装置,包括以下步骤:S1:将纤维制备成预制件;S2:对预制件进行浸渍:将预制件放入浸渍装置,抽真空装置将真空袋内的空气排出,先驱体进入浸渍装置内,对预制件进行浸渍;S3:对预制件进行固化:将真空袋以及真空袋内的所有结构一起放入烘箱内,所述烘箱进行加热。S4:对预制件进行烧结:将预制件放入裂解炉进行烧结,在烧结过程中,往裂解炉充入氩气,并进行排气;S5:重复步骤S2‑S4若干次后,将预制件从裂解炉取出,得到陶瓷基纤维复合材料。本发明能够制备形状复杂的预制件,提高了浸渍效果,降低最后成品的孔隙率,增加了致密性,提高了性能。
