Design of Structural Parameters for Paper-Based Spherical Porous Materials and Its Influence on Static Cushioning Performance

In order to improve the cushioning performance of cushioning materials and reduce the use of materials, the structural parameter is designed and the static cushioning performance of Paper-based Spherical Porous Materials is analyzed in this paper. The cushioning coefficient and the stress-strain curve are investigated under the different structural parameters. The results show that the different structural parameters of the materials affect the static cushioning performance of such materials. The compression process can be divided into three stages: linear elasticity, yielding, and densification. As the pore size decreases, the yield value increases progressively, indicating an enhancement in the rigidity of the paper-based spherical porous materials and a reduction in cushioning effectiveness. Smaller pore sizes result in improved cushioning performance for paper-based spherical porous materials. Increasing the thickness enhances the cushioning performance of paper-based spherical porous materials.
