The fiber architectures of the stomatopod dactyl club lead to an effective toughening mechanism. Composites with sinusoidally periodic helicoidal (Herringbone-type) fiber architectures were fabricated using additive manufacturing and examined under dynamic loading. Under compression at different strain rates, stress distribution was found more uniform in the Herringbone-type structure than that in the Bouligand-type one because of fiber flattening. Under dynamic compression, Herringbone-type structures with amplitude gradients resisted large strains without significant damage, leading to greater energy absorption. Simulations indicated that the Herringbone-type structure mitigated the impact waves and facilitated uniform stress redistribution, whereas the Bouligand-type structure filtered the waves. These findings would shed light on the future designs of impact-resistant bioinspired materials.
