摘　　要：目的设计一款增强型蜂窝芯层创新结构。方法通过平板粘合尺寸决定新增芯层在六边形蜂窝胞元中的形状,选取直线肋板结构为研究对象,对比创新结构与常规结构的面外承载性能,在现有蜂窝芯层加工工艺的基础上,对此蜂窝芯层的成型工艺及参数进行分析研究。结果新结构可实现平板状粘合,当胞元内粘合尺寸为胞元边长的0.625倍时,在蜂窝孔内形成直线肋板结构,分布均匀,创新结构比常规结构的平台应力提高了315.74%,同时针对该结构改进设计了半自动及全自动粘合工艺方法。结论创新结构科学稳定,承载性能得到显著提高,芯层粘合工艺改动小,能为扩充夹层板材结构及成型工艺提供参考。The work aims to design an innovative structure of reinforced honeycomb core. The shape of the new core layer in the hexagonal honeycomb cell was determined based on the bonding size of the plate. With the straight rib structure selected as the research object, out-plane bearing capacities of the innovative structure and common structure were compared. Based on the existing processing technology of the existing honeycomb core, the forming process and parameters of such honeycomb core were analyzed and researched. The new structure could realize bonding in plate state. When the bonding size in cell element was 0.625 times the size of side length of cell element, the straight rib ture could be formed in honeycomb core and distributed uniformly. The plateau stress of the innovative structure was 315.74% higher than that of the common structure. Besides, semi-automatic and fully automatic bonding processes were designed with respect to such structure. The innovative structure is scientific and stable, the bearing capacity is significantly improved, and the core bonding process changes little, which could provide a reference for the expansion of sandwich plate structure and forming process.
