How is the Structure of Nacre Related to Its Properties?
The structure of nacre consists of microscopic aragonite platelets arranged in a 'brick-and-mortar' pattern. This intricate architecture, stabilized by organic matrix layers, allows for energy dissipation and crack resistance. When stress is applied, the organic layers stretch and absorb energy, preventing cracks from propagating through the material. This hierarchical structure can be mimicked in synthetic materials to enhance their mechanical properties.
