Publication number: 20240059044Abstract: A honeycomb core with S-shaped reinforced structures includes multiple cylindrical unit cells arranged in a honeycomb shape and with a polygonal cross section, the cylindrical unit cells are divided into plain unit cells and S-shaped reinforced unit cells, an inner cavity of the plain unit cell is hollow, and the inner cavity of the S-shaped reinforced unit cell is equipped with an S-shaped reinforced structure, a cross section of the S-shaped reinforced structure is S-shaped and the inner cavity of the S-shaped reinforced unit cell is divided into two halves on average. This structure guides the load-transfer path effectively by controlling the rotation of S-shaped reinforced cells, it changes the position of plastic collapse in the structure, and finally changes the peak load of the core. Under different working conditions, the design of the arrangement of S-shaped reinforced structures can make the core produce different peak loads.Type: ApplicationFiled: July 26, 2023Publication date: February 22, 2024Applicants: Dalian Jiaotong University, Dalian University of TechnologyInventors: Shanshan SHI, Zhi SUN, Xin ZHOU, Bingzhi CHEN, Yonghua LI, Yuedong WANG
