The alligator gar (A. spatula) is covered with bony scales and an enamel-like surface layer. The scales form a tridimensional pattern in which neighboring scales overlap in such a manner that the thickness conforms and the sum of the overlaps is constant. The mechanical properties and structure are correlated and the tridimensional pattern revealed by computerized tomography is transferred by additive manufacturing to a magnified array of idealized, identical tiles. It is demonstrated that flexibility is maintained while protection is retained. This design is proposed as a model for bioinspired flexible ceramic composite personal armor. Research funded by AFOSR MURI.
