[0020] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any manner.

[0021] As explained in the above background technology, the current method for improving the out-of-plane mechanical properties of honeycombs requires the use of more raw materials to improve the load-bearing and energy-absorbing performance, which leads to the problem of balancing the requirements for lightweight structure and high load-bearing and energy-absorbing performance.

[0022] Under the premise that the raw materials remain unchanged, optimizing the cross-sectional shape of the honeycomb structure can improve the load-bearing and energy absorption performance. The current cross-sectional shape design method is to insert substructures into the traditional hexagonal cells or combine different geometric topological structures into the original honeycomb to enhance the load-bearing and energy absorption performance. This method also requires the use of more raw materials to improve the load-bearing and energy absorption performance.

[0023] Few studies have been devoted to designing pure multi-walled cells to improve load-bearing and energy absorption properties. In addition, most honeycomb structures focus on complex configurations and rely on 3D printing technology, which makes it difficult to meet the processability of traditional honeycomb molding processes.

[0024] In response to the above problems, the present invention provides a high out-of-plane load-bearing energy-absorbing honeycomb structure and a design method thereof. The honeycomb structure is simple and easy to manufacture using traditional molding processes, which can solve the technical problem of weak out-of-plane load-bearing energy-absorbing performance of traditional honeycombs.
