Abstract

Thermally sprayed ceramics, when infiltrated with polymer, exhibit synergistic increases in strength and toughness. The structure of such composites-a dense, brick-mortar arrangement-is strikingly similar to that of nacre, as are the mechanisms underlying the robust mechanical behavior. This industrial-scale process thus presents an exciting tool for bio-mimetic exploration.

Keywords: abalone shell; biomimetic; fracture toughness; nacre; thermal spray.
