摘要

Cushioning is one of the most commonly touched materials in real life and the most widely used component in industry, packaging and transport, and personal protection. In this paper, a spacer fabric-reinforced silicone rubber flexible composite material inspired by the bone-seam joint structure is proposed. The interfacial interlock is achieved by stacking vertical strips of spacer fabric on top and bottom, and then composite with silicone rubber to produce flexible composites. The effects of fabric structure and stacking method on the compression performance of silicone rubber composites were investigated. In addition, the effects of silicone filler rate, impact energy, and stacking method on the impact performance of silicone rubber composites were also investigated, which is of great significance for the development and research of flexible cushioning materials. The results show that the energy absorption of the composites increases with the increase of silica gel filling amount. The energy absorption of composites also increases with the increase of impact energy. Compared with side-by-side and back-to-back stacking methods, the interlocking stacks have a greater ability to carry loads when subjected to compression and have the best compressive properties. In addition, the energy absorption is higher due to the deflection of cracks that occurs in the interlocking stacks when impact damage occurs.
