Hot auxiliary material extrusion direct-writing 3D printing method for continuous fiber reinforced ceramic
The invention relates to a continuous fiber reinforced ceramic thermal auxiliary material extrusion direct-writing molding 3D printing method, which comprises the following steps: (1) preparing thermoplastic ceramic ink with the melting temperature of 75-90 DEG C, and injecting the thermoplastic ceramic ink into a heatable direct-writing molding charging barrel; (2) heating the heatable direct-writing forming charging barrel to a specified temperature, enabling the ceramic ink to be in a molten state, supplying the ceramic ink to a coaxial nozzle by an extrusion system, fully combining the ceramic ink with continuous fibers, co-extruding into filaments, and stacking layer by layer to form a continuous fiber reinforced ceramic composite material preform; and (3) degreasing, vacuum impregnating and sintering the continuous fiber reinforced ceramic composite material preform to obtain the continuous fiber reinforced ceramic matrix composite material. According to the preparation method, the bonding strength between the fiber and the ceramic is effectively improved, the melting temperature of the thermoplastic ceramic ink is relatively low, other materials can be recycled, and the preparation method is simple in structure, low in cost and environmentally friendly.
本发明连续纤维增强陶瓷的热辅助材料挤出直写成型3D打印方法，包括步骤：(1)制备熔融温度为75‑90℃的热塑性陶瓷墨水，将所述热塑性陶瓷墨水注入可加热直写成型料筒中；(2)所述可加热直写成型料筒升温至指定温度，陶瓷墨水呈熔融态，挤出系统将所述陶瓷墨水供给至同轴喷嘴，陶瓷墨水与连续纤维充分结合后共挤出丝，逐层堆叠形成连续纤维增强陶瓷复合材料预制体；(3)将所述连续纤维增强陶瓷复合材料预制体脱脂、真空浸渍和烧结，得到连续纤维增强陶瓷基复合材料。本发明有效提高了纤维与陶瓷间的结合强度，热塑性陶瓷墨水熔融温度相对较低，且其余料可回收利用，是一种结构简单、低成本、环保的制备方法。
