Abstract3D needle‐punched CF/PEEK composites are a kind of composites with promising applications in multiple fields, such as implant materials, but their mechanical properties in the Z‐axis and interlaminar are still weak at present. In this study, a bio‐inspired reinforcement structure based on ladybug forewing was developed to achieve directed reinforcement of 3D needle‐punched CF/PEEK composites. Carbon fiber yarns were stitched into the 3D needle‐punched CF/PEEK preforms according to the set structure, and the bio‐inspired CF/PEEK composites were obtained after hot pressing. The interlaminar and in‐plane mechanical properties of the composites were investigated at different stitch lengths. The results showed that the addition of the bio‐inspired structure greatly improved the interlaminar shear strength of the composites, reaching 111.30 MPa, an enhancement of 95.06%. The in‐plane mechanical properties, including tensile, flexural, and compression, were also significantly improved to different degrees. The “structure‐effect” relationship in the bio‐inspired CF/PEEK composites was investigated, and the effectiveness of such a bio‐inspired reinforcement structure was demonstrated. This new reinforcement strategy provides a new idea for the improvement of the mechanical properties of multi‐stage carbon fiber‐reinforced thermoplastic resin matrix composites.Highlights The in‐plane and interlaminar mechanical properties of composites were simultaneously improved. Up to 95.06% improvement in interlaminar shear strength. A novel bionic strategy of directional reinforcement was developed. The “structure‐effect” relationship in the composites was investigated.

“…Such mechanical features of the materials are responsible for composite behavior regarding deformations and load resistance, and thus their geometrical stability. Materials stiffness or Young's modulus, as well as impact strengths and materials ductility, are very important to be investigated for the biomaterials before implemented in various products as they will determine the functional requirements for a certain application [4,[20][21][22][23]. Thus, all these mechanical features were appropriately and carefully examined bio-composite materials under the effect of various reinforcing conditions including chemical treatment of the fibers [24][25][26][27].…”

This paper aims to integrate the response surface methodologies to investigate the effect of the cellulose and hemicellulose contents on the mechanical properties of the polypropylene-based composites with green fiber reinforcement conditions. In this study, the tested data are collected from various literature resources demonstrating the green fiber type, the chemical treatment condition, and the resultant mechanical properties, i.e., the tensile modulus and tensile strength. Accordingly, the response surface analysis is utilized to obtain a high-accuracy first order regression model to formulate the influence of the cellulose, hemicellulose, and the treatment condition on the tensile characteristics of the green composite. The results showed that the biocomposites samples with higher cellulose and lower hemicellulose percentages have significantly better tensile modulus properties. However, such samples would have lower tensile strength qualities. Additionally, the presence of chemical treatment can significantly improve the tensile properties of the polypropylene-based composites.

“…The increasing trend of exploring green materials is due to the fact that their overall properties are more desirable than traditional materials. 15 When looking into the commercially available FMLs, synthetic fibers such as carbon, aramid and glass fibers are the primary reinforcement to be embedded in the matrix. Given the increasing environmental awareness and consciousness, researchers and scientists are urged to develop more promising and sustainable green materials.…”

The development of hybrid materials consisting of alternating layers of metal alloys and polymeric composites has revolutionized the engineering field. These metal‐composite laminates combine the merits of each individual component, forming advanced and promising structures which could be employed for structural applications. The low fatigue crack growth rate and high damage tolerance of these materials are particularly fascinating. When developing metal‐composite laminates with superb functional properties, the combination of several metal surface treatment techniques is a common practice to ensure optimum metal‐composite adhesion. Today, a new cutting‐edge manufacturing technique utilizing nano‐porous network film has been established to get rid of the massive infrastructure of conventional autoclave techniques and produce first‐rate materials. Even though various techniques can be adopted to manufacture metal‐composite laminates, the selection of the techniques is highly dependent on the nature of the polymer matrix. After the manufacture of the metal‐composite laminates, post‐stretching is considered a critical step to alleviate the unfavorable residual stress to ensure the optimum performance of these materials for long‐term service. When dealing with natural fibers, it is worth mentioning that the processing temperature should be limited to below 200°C regardless of manufacturing technique to avoid fiber degradation. Metal‐composite laminates consisting of synthetic/natural fibers are considered a viable option to offset the demerits of each kind of fibers. By incorporating fatigue‐resilient natural fibers in the laminates, it is expected that the overall fatigue resistance of the laminates can be apparently enhanced, which is in line with the initial goal of developing metal‐composite laminates.Highlights Fiber bridging offers fiber‐metal laminates with superior fatigue properties. Metal surface treatment is vital to ensure an optimum fiber‐bridging mechanism. A novel out‐of‐autoclave method can produce first‐grade fiber‐metal laminates. Post‐stretching is needed to lessen residual stress in fiber‐metal laminates. Hybrid fiber‐metal laminates are feasible for structural applications.
