Nacre-like structure from reinforced polymersStrong, tough but light is the desired combination of properties for numerous applications but one that is rarely found in artificial materials. Now researchers at ETH Zurich have developed a new ......
1c), the nacre-like structure may not always be a template for impact-resistant structures. Besides the above single bioinspired architecture design, the hybrid design combing multiple bioinspired architectures also attracts intense interest in achieving enhanced impact resistance, for example, the ...
Taking a leaf out of Nature's book, the use of nacre-like structure in the materials synthesis has generated notable successes in creating novel structural composites but has yielded few practical advances in metals. Here we have successfully architected the intricate hierarchical microstructure, the ...
Natural materials, such as nacre (mother-of-pearl), can have outstanding mechanical properties due to their complicated architecture and hierarchical structure at the nano-, micro- and meso-levels which have evolved over millions of years. This review describes the numerous experimental methods ...
While the use of metals as the “mortar” phase is an attractive option to maximize fracture toughness of bulk composites, non-mechanical functionalities potentially enabled by the presence of a metal in the structure remain relatively limited and unexplored. Using iron as the mortar phase, we ...
Nanofibers and nanosheets form a typical brick-and-mortar structure, which exhibits mechanical robustness compared with other reported materials. Additionally, the heterostructure contributes to both restraining concentration polarization and generating spontaneous potential gradient. Thus, based on the confined ...
Inspired by nacre's sophisticated "brick-and-mortar" structure, multilayered polyether amine (PEA)/graphene oxide (GO) hybrid building blocks were incorporated onto the surface of carbon fiber via Layer-by-Layer (LbL) assembly to strengthen and toughen the interphase of composites. Impressive ...
TheRcand relatively promising interfacial thermal properties of STC-2 in addition to the nacre-like structure were further elucidated theoretically by molecular dynamics (MD) simulation. We built models of interfacial thermal resistances between Al film and commercial epoxy adhesives, W-SPU/TCM, and ...
Design and preparation of silicon nitride composite with high fracture toughness and nacre structure To mimic the laminated structure of nacre, Si3N4 matrix ceramic layer can be obtained through compacting rolling method. To mimic the secondary toughening ... Y Huang,HN Hao,YL Chen,... - 《...
In general, the typical architecture of nacre has been known as the “brick-and-mortar” (BM) structure, the “brick” is the major load-bearing constituent which provides strength, while the “mortar” acts as the lubricant for bricks. In the case of appropriate interface [7], the ...
