Continuous fiber reinforced ceramic matrix composite 3D printing method based on photocuring ceramic slurry and fiber co-extrusion
The invention discloses a rapid forming method of a continuous fiber reinforced ceramic matrix composite material based on co-extrusion of photocuring ceramic slurry and fibers. The rapid forming method comprises the following steps: firstly, mixing photocuring photosensitive resin with ceramic powder with different particle size grading to obtain different solid-phase photocuring ceramic slurry; the 3D printer supplies the high-solid-phase light-cured ceramic slurry to the tail end of the coaxial nozzle, the low-solid-phase light-cured ceramic slurry and the continuous fibers are combined in the infiltration tank and then jointly extruded to the coaxial nozzle, the continuous fibers infiltrated at the tail end of the coaxial nozzle and the high-solid-phase light-cured ceramic slurry are mixed again and then jointly extruded, and a prefabricated body is formed through layer-by-layer stacking; and finally, carrying out vacuum impregnation and high-temperature sintering treatment on the preform to obtain the final continuous fiber reinforced ceramic-based composite material based on photocuring ceramic slurry/fiber co-extrusion. The continuous fiber reinforced ceramic matrix composite material is prepared, the printing precision and the printing quality are effectively improved, and integrated rapid forming and manufacturing of a complex structure can be achieved.
一种基于光固化陶瓷浆料和纤维共挤出的连续纤维增强陶瓷基复合材料的快速成形方法，先将光固化光敏树脂与不同粒径级配的陶瓷粉体混合得到不同固相光固化陶瓷浆料；3D打印机将高固相光固化陶瓷浆料供给至同轴喷嘴末端处，低固相光固化陶瓷浆料与连续纤维在浸润槽中结合后共同挤出至同轴喷嘴，在同轴喷嘴末端浸润的连续纤维与高固相光固化陶瓷浆料再次混合后共同挤出，逐层堆叠形成预制体；最后将预制体进行真空浸渍和高温烧结处理，得到最终的基于光固化陶瓷浆料/纤维共挤出的连续纤维增强陶瓷基复合材料；本发明实现连续纤维增强陶瓷基复合材料的制备，有效提升打印精度和打印质量，可以实现复杂结构的一体化快速成形制造。
