AI Technical Summary
Existing bulletproof helmets are mostly designed with a single Bouligand biomimetic structure, failing to fully combine single and double helix structures. This results in insufficient overall mechanical performance in extreme environments, making it impossible to effectively improve the helmet's impact resistance and strength.
A multi-layer biomimetic impact-resistant material was designed, comprising a biomimetic impact-resistant surface layer, a biomimetic energy-absorbing and transferring layer, and a biomimetic toughening and crack-resistant base layer. It adopts the principle of synergistic enhancement of strength, toughness, and rigidity of biomimetic composite materials. Through unidirectional and bidirectional spiral-laid biomimetic structural layers, combined with organic polymer fibers and thermosetting resins, a buffer layer and a biomimetic structural layer are formed, thus optimizing the structural design of the helmet.
It significantly improves the helmet's impact resistance and strength, while reducing the helmet's areal density, thus enhancing its protective capabilities in extreme environments.
