Abstract
A toughened composite material, having a first phase defining a matrix and a plurality of typically second phase particles dispersed in the first phase matrix. Each respective particle is characterized by a predetermined geometric architecture, such as a spiral shape. The presence of the geometrically distinct dispersed second phase operates to deflect and attenuate crack propagation.
