Natural dermal armors are serving as a source of inspiration for the design of “next-generation” structural materials. The dynamic response of natural dermal armors is arguably the most relevant to their performance. Here, dynamic loading of fish scales was performed in uniaxial tension and transverse puncture, under strain rates spanning seven decades. To understand spatial variations, specimens were prepared from scales of the head, middle and tail regions of multiple Asian carp. The scales exhibited a significant increase in the resistance to failure with loading rate for both loading orientations. However, the rate sensitivity was substantially higher for transverse loading than for in-plane tension. Spatial variations were greatest for the transverse loading orientation as well, and for scales of the head region. The layered microstructure of fish appears to have evolved to be most effective at resisting dynamic puncture. Preliminary efforts of developing laminates with similar behavior are presented.
