“…Recently, Han et al [17] created a basalt fibre-reinforced sandwich composite attempting to mimic the Herringbone pattern with a 2D woven fabric and the periodic region with layers of discontinuous basalt fibres. Their results showed that, compared to a traditional basalt discontinuous fibre composite, the club-inspired samples achieved higher tensile and compressive moduli, higher tensile strength and higher impact resistance.…”

In this work, we design, prototype, test and analyse the first high-performance Herringbone-Bouligand microstructure (with Carbon Fibre Reinforced Plastic (CFRP)) inspired to the high-impact-resistant mantis shrimp's dactyl club. To this end, we devised the first prototyping procedure to manufacture point-by-point tailorable Herringbone-Bouligand CFRP microstructures; this was based on the micro-moulding of uncured CFRP prepreg, and led to mimicking features of the club microstructure never achieved before with CFRPs. We investigated the damage tolerance of the prototyped Herringbone-Bouligand CFRP laminates, compared against 'classical' Bouligand CFRP laminates, using quasistatic indentation tests. Our test results show that the Herringbone-Bouligand microstructure resulted in delayed onset of delaminations, reduced in-plane spreading of damage, increased energy dissipation capability, and in the containment of damage within the tailored Herringbone-Bouligand region. We conclude that Herringbone-Bouligand CFRP microstructures offer an excellent tailorable damage-tolerant solution with great potential for composite applications where resistance to through-thethickness loads is paramount.

“…Among these structures, the dactyl club of the mantis shrimp has received more attention due to its remarkable damage tolerance 26,27 . Han et al 28 revealed that the impact strength of the bionic herringbone samples increased by 30.3% compared to that of the conventional basalt fiber composite. Wu et al 29 developed a discontinuous fibrous Bouligand architecture that exhibits a hybrid toughening mechanism, increasing in fracture resistance (+43.3%).…”

This 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 An impact‐resistant gradient waviness structure is discovered in trap‐jaw ants. Bioinspired interlayer hybrid laminate is fabricated by mold pressing. The hybrid laminate restrict damage propagation and improve residual strength.

“…[9,10] As a result, the BFs can be seen as the only candidate to allow the preparation of highperformance structural green composites. [11,12] However, the use of native fibers hinders the creation of strong chemical bonds with the polymeric matrix. Therefore, the BFs should priorly be surface-treated to improve their wettability and establish chemical links with the matrix.…”

In this study, a partially bio-based composite was prepared from a highperformance thermosetting resin, namely the phthalonitrile, and chopped basalt fibers (CBFs). Aiming to create strong covalent bonds between the matrix and the fillers, the CBFs were priorly grafted with an epoxy-ended hyperbranched poly (trimellitic anhydride ethylene glycol) ester (EHBP). The modification technique was validated by infrared spectroscopy and scanning electron microscopy (SEM).The effect of the fillers treatment on the mechanical performances highlighted remarkable enhancements in the tensile, bending, and Charpy impact properties.For instance, the tensile strength and modulus values were 30% and 20% higher than those afforded by the pristine fibers. Meanwhile, the SEM analysis of the fractured surfaces clearly confirmed the excellent state of adhesion and dispersion of the treated fillers with the polymeric matrix. Additionally, the influence of different quantities of EHBP-CBFs on the composite properties further revealed the exceptionally high mechanical properties of the developed materials. In fact, the tensile strength attained exceptional value of about 310 MPa for the composite of 20 wt% of EHBP-CBFs. Overall, this study unraveled the great potential of these newly developed materials with a focus on overcoming the debonding phenomena and easing the stress-transfer between the constituents.
