Composite ceramic with honeycomb fiber structure and preparation method of composite ceramic
The invention relates to composite ceramic with a honeycomb fiber structure. The composite ceramic comprises a cell wall and cell bodies, wherein the cell wall is divided into a plurality of compartments; the compartments are filled with the cell bodies; and the cell wall is made of high-toughness ceramic, and the cell bodies are made of high-strength ceramic. The preparation method comprises the following steps: high-strength ceramic slurry and high-toughness ceramic slurry are prepared; a paraffin core is inserted into a casting mold for occupying, high-strength ceramic slurry is injected into the casting mold, after the high-strength ceramic slurry is solidified, heating is conducted to enable the paraffin core to be melted and flow out, and the cell wall and the compartments defined by the cell wall are formed; high-toughness ceramic slurry is injected into the casting mold to fill the spaces of the compartments, and the high-toughness ceramic slurry is cured to obtain a wet green body with a honeycomb structure; and pressing treatment and sintering treatment are conducted on the wet green body with the honeycomb structure to obtain the composite ceramic with the honeycomb fiber structure. Compared with the prior art, the composite ceramic has the advantages of good ceramic structure controllability, high strength, good toughness, high light transmittance, no aging and the like.
本发明涉及一种蜂窝纤维结构的复合陶瓷，包括区划形成多个隔室的胞壁以及填充在隔室内的胞体；胞壁的材质为高韧性陶瓷，胞体的材质为高强度陶瓷；制备过程为制备高强度陶瓷浆料和高韧性陶瓷浆料；在铸造模具中插入石蜡芯占位，在铸造模具中注入高强度陶瓷浆料，待高强度陶瓷浆料固化后，加热使石蜡芯融化流出，形成胞壁和由胞壁围成的隔室；在铸造模具中注入高韧性陶瓷浆料填充隔室的空间，待高韧性陶瓷浆料固化后将得到的具有蜂窝结构的湿坯体；的蜂窝结构的湿坯体经过压制处理、烧结处理得到的蜂窝纤维结构的复合陶瓷。与现有技术相比，本发明具有陶瓷结构可控性能好、强度高、韧性好、高透光和不老化等优点。
