Strombus gigas inspired biomimetic ceramic composites via SHELL—Sequential Hierarchical Engineered Layer Lamination
چکیده انگلیسی

Nature has produced remarkable structural designs based on many millennia of evolutionary optimization. Biological materials, such as the sea-shell, possess unique microstructures and properties that provide inspiration for the next generation of structural ceramics. Strombus gigas (Queen conch) shells contain a hierarchical, multilayered, crossed-lamellar architecture built with two natural materials (calcium carbonate and protein) with at least three identifiable scales (or orders) of structure. Drawing on Strombus gigas for inspiration, we have developed a new process to realize such complex micro-architectures in macroscopic form. SHELL (Sequential Hierarchical Engineered Layer Lamination) is a thermoplastic forming process that is capable of producing the third order structural complexity over the micron-millimeter length scales. We have fabricated silicon nitride—boron nitride ceramics via SHELL that are endowed with excellent damage tolerance, exhibit graceful failure, and exhibit toughening mechanisms similar to those observed in Strombus gigas.
