Fabric‐based materials have demonstrated promise for high‐performance wearable applications but are currently restricted by their deficient mechanical properties. Here, this work leverages the design freedom offered by additive manufacturing and a novel interlocking pattern to for the first time fabricate a dual‐faced chain mail structure consisting of 3D re‐entrant unit cells. The flexible structured fabric demonstrates high specific energy absorption and specific strength of up to 1530 J kg−1 and 5900 Nm kg−1, respectively, together with an excellent recovery ratio of ≈80%, thereby overcoming the strength–recoverability trade‐off. The designed dual‐faced structured fabric compares favorably against a wide range of materials proposed for wearable applications, attributed to the synergetic strengthening of the energy‐absorbing re‐entrant unit cells and their unique topological interlocking. This work advocates the combined design of energy‐absorbing unit cells and their interlocking to extend the application prospects of fabric‐based materials to shape‐adaptive protection.
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.
