| Abstract Scope |
Fibers and fibrils are the dominant structural biomaterial archetype in plants and animals and make some of Nature’s strongest and toughest materials. Fibrils are typically embedded into a matrix to form a composite, where fiber/matrix interfacial breakdown is an issue, as is anisotropy of the obtained mechanical properties. Substantial flattening of fibers can significantly increase the surface area and thus alleviate some of these issues by enhancing interfacial bonding. Existence of such materials systems in Nature has largely been overlooked. We have further explored extreme cases of this archetype: tapes. We found that tape/tape bonding exhibits an unexpected behavior that can lead to self-strengthening adhesive bonds, and we have developed an analytical description that fully explains it. Employing this effect, we have further realized matrix-free “composites” with tunable stiffness, strength, and toughness. |
