4D printing technology-based SiC ceramic structure for airplane and preparation method of 4D printing technology-based SiC ceramic structure
The invention relates to the technical field of 4D printing, in particular to a 4D printing technology-based SiC ceramic structure for an airplane, which comprises a straight area and a bent area. Thestraight area and the bent area are both formed by integrally forming and printing a ceramic matrix through the 4D printing technology. The ceramic matrix is formed by mixing printing slurry, choppedfibers and toughening elements. The preparation method comprises the following steps: step A, preparing the ceramic matrix, and mixing the printing slurry, the chopped fibers and the toughening elements according to a volume ratio of 15: 3: 2; and B, printing the prepared ceramic matrix through a 4D printer to obtain a finished product structure. Superplasticity of the ceramic structure can be achieved through compounding of the chopped fibers and the toughening elements, the toughness of the bent area 2 of the ceramic structure is fundamentally improved, the breaking risk is reduced, the manufacturing process is simple, material selection is convenient, and the printing cost is reduced.
本发明涉及4D打印技术领域，具体为一种基于4D打印技术的飞机用SiC陶瓷结构，所述SiC陶瓷结构包括：平直区和弯折区；所述平直区和弯折区均由陶瓷基体通过4D打印技术一体成型打印而成；所述陶瓷基体由打印浆料、短切纤维和增韧元素混合而成。本发明的一种制备方法，包括以下步骤：步骤A：配置陶瓷基体，将打印浆料、短切纤维和增韧元素按体积比15∶3∶2进行混合；步骤B：将配置好的陶瓷基体通过4D打印机打印得到成品结构。该发明通过短切纤维与增韧元素的复合可实现陶瓷结构的超塑性，从根本上改善陶瓷结构弯折区2处的韧性，降低断裂的风险，且制作过程简单，选材方便，降低打印成本。
