Abstract:Polymer foams are widely used as cushioning and impact protective materials, while the single foam is susceptible to densification by concentrating pressure at the point of impact, thus reducing the protection effect. Herein, inspired by the tortoise shell, a composite structure composed of a poly(vinyl chloride) (PVC) hard layer and a thermoplastic polyurethane (TPU) foam soft layer was developed, which demonstrated significantly enhanced impact protection and energy absorption performance. The numerical mode… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
