AI Technical Summary
Existing honeycomb cores face challenges in achieving high bending stiffness and strength at minimal weight due to thin cell walls that buckle under compression and shear loads, and limitations in production size and efficiency.
A hierarchical sandwich core design with macroscopic honeycomb cells and mesoscopic cellular cores, using single thickness sandwich material cell walls connected by multi-arm structures, such as three, four, or six arms, to enhance load transfer and mechanical strength, while allowing for large sheet sizes and efficient production.
The design achieves superior mechanical properties per weight, with improved compression and shear buckling resistance, and enables cost-effective, large-scale production of lightweight honeycomb structures.
