Synthesis of Nacre-Like Structures using Novel Fabrication Techniques

摘要

This proposal addresses the nacre in the abalone shell and the methods that will be taken to fabricate and test a bioinspired material based on its structure. Our objectives are 2-fold: (1) to fabricate a nano/micro- laminate that mimics the nacre in the abalone shell using engineering ceramic compositions and (2) to test these laminates and determine modes of fracture and energy absorption. The main focus is to distinguish the role of mineral bridges, organic ligament stretching and asperities on the toughening behavior.
