Abstract
AbstractThis study investigates the rapid mandible strike behavior of trap‐jaw ants (Odontomachus monticola), a highly aggressive species of terrestrial social organisms. An impact‐resistant gradient waviness structure is discovered in the mandibles of trap‐jaw ants. The gradient waviness structure is incorporated into the fiber laminates to enhance their impact resistance and damage tolerance. Bioinspired interlayer hybrid laminates with both unidirectional and woven arrangements were fabricated using the mold press forming technique. The impact resistance and damage tolerance of the bionic laminates are investigated through low‐velocity impact, ultrasonic C‐scanning, and compression after impact tests. The results indicate that hybrid laminates play a key role in limiting damage propagation and improving energy dissipation capacity. The hybrid configuration effectively mitigates crack propagation, enhances load‐bearing capacity, and improves residual compressive strength. Bionic laminates offer an efficient solution for enhancing damage tolerance against through‐the‐thickness loads.Highlights
