Photocureable additive manufacturing method of active filler reinforced precursor ceramic composite material
The invention discloses a photocureable additive manufacturing method of an active filler reinforced precursor ceramic composite material, which comprises the steps of fully mixing a ceramic precursor and photosensitive resin to obtain a photosensitive precursor, adding a dispersing agent and an initiator into the photosensitive precursor, and fully mixing to obtain a liquid mixture; adding an activity reinforcing filler into the liquid mixture, and fully mixing to obtain uniformly dispersed photocureable slurry; carrying out printing molding on the prepared photocureable slurry through a photocureable additive manufacturing technology to obtain a biscuit; and carrying out thermogravimetric analysis on the biscuit, setting a pyrolysis temperature program according to a thermogravimetric curve of the biscuit, and pyrolyzing the biscuit in a tubular furnace in an inert atmosphere. The method has the advantages that an activity reinforcing filler control precursor pyrolysis method and a photocureable additive manufacturing technology are combined, integrated manufacturing of low shrinkage, low defect, high mechanical property and high ceramic yield of the filler reinforced precursor composite ceramic material is realized, and the method has the advantages of high forming speed, good precision, high efficiency and mold-free manufacturing.
本发明公开了一种活性填料增强前驱体陶瓷复合材料的光固化增材制造方法，将陶瓷前驱体和光敏树脂充分混合，得到光敏前驱体，向光敏前驱体中加入分散剂和引发剂并充分混合，得到液体混合物；向液体混合物中加入活性增强填料并充分混合，得到分散均匀的光固化浆料；通过光固化增材制造技术将制备好的光固化浆料打印成型，得到素坯；对素坯进行热重分析，根据素坯的热重曲线设置热解温度程序，将素坯在管式炉中于惰性气氛下进行热解。优点是：将活性增强填料控制前驱体热解法与光固化增材制造技术结合，实现了填料增强的前驱体复合陶瓷材料的低收缩、低缺陷、高力学性能、高陶瓷产率的一体化制造，具有成型速度快、精度好、效率高和无模制造的优点。
