摘要
Abstract
Ceramic materials exhibit broad application prospects in the aerospace field due to their excellent properties such as high strength,low density,high temperature resistance,and corrosion resistance.To address the limitations of traditional forming methods in fabricating ceramic parts with complex structures,this paper investigates the Vat Photopolymerization(VPP)additive manufacturing process of barium titanate(BT)/hydroxyapatite(HA)composite piezoelectric ceramics.By op-timizing the ceramic powder ratio,photosensitive resin composition,and additive content,a BT/HA composite piezoelectric ceramic slurry with a solid loading of 40 vol%,characterized by high solid content and high dispersibility,was successfully prepared,wherein the volume ratio of BT to HA is 4:1.Based on the Beer-Lambert law,the optimal printing process param-eters of the slurry were predicted and analyzed,and BT/HA composite ceramic green bodies with good formability were fab-ricated.The results show that the minimum structural feature size of the obtained green bodies reaches 100 μm,and the maximum unsupported span of the cantilever beam structure is 10 mm.关键词
