Research on a cushioning structure for the midsoles of sports shoes based on the three-dimensional pore structure of loofahs

A study based on the three-dimensional structural properties of loofahs was carried out to model and analyse the vibration damping characteristics of reinforced composite loofah materials and structures. The structural model was tested for Young's modulus compression by using finite element techniques. Based on the results of the study, a lightweight cushioning structure based on a reinforced composite loofah with polygonal pores was developed and used as a midsole cushioning module for running shoes. The structure was then subjected to dynamic shock vibrations, compression, vibration damping and loss factor, fatigue testing and compression testing. The results of the tests showed that the midsole achieved an ideal balance of weight and mechanical performance and was an excellent cushioning structure with high durability.
