The ceramic honeycomb sandwich structures of 3 mol% yttria-stabilized tetragonal ZrO₂ (3Y-TZP) material were fabricated by an additive manufacturing technique based on the digital light processing (DLP) system. The bending behaviour of hexagonal and square honeycomb sandwich structures was investigated with three-point bending test. The effects of geometric parameters, including the thickness of the face-sheet, the height of the cell, the thickness of the cell wall and the size of the cell, were studied through experiments carefully. The results illustrated that the bending strength of the ceramic honeycomb sandwich structure can reach 170 MPa at a relative density of 41.72%. The geometric parameters of the honeycomb core were more critical than the sandwich face-sheet. The cell size, cell wall thickness and cell height were found to be the preferred geometric parameter for justifying the bending resistance performance of the ceramic sandwich panel. Square honeycomb demonstrated better bending performance than the hexagonal honeycomb. This study provides a new basis for further studies on the ceramic lightweight structures.

3 mol％氧化钇稳定的四方ZrO ₂的陶瓷蜂窝夹层结构（3Y-TZP）材料是通过基于数字光处理（DLP）系统的增材制造技术制造的。通过三点弯曲试验研究了六角形和正方形蜂窝夹层结构的弯曲行为。通过实验仔细研究了几何参数的影响，包括面板的厚度，单元的高度，单元壁的厚度和单元的尺寸。结果表明，相对密度为41.72％，陶瓷蜂窝夹层结构的弯曲强度可达170 MPa。蜂窝芯的几何参数比夹心面板更重要。像元大小 发现小室壁厚和小室高度是证明陶瓷夹芯板的抗弯曲性能合理的优选几何参数。方形蜂窝具有比六角形蜂窝更好的弯曲性能。该研究为进一步研究陶瓷轻量化结构提供了新的依据。
