“…The stress distribution on the CF/PEEK composites was simulated by COMSOL software (Figure 12(c),(d),(e)). 33,34 Figures (e),(d) reveal that the material could deform when a load is applied to the centre of the material. When the load is applied to the front surface of the material, the front of the material is subject to extrusion stress, whilst the back of the material bears the maximum shear and tensile stresses.…”

The interfacial interactions of carbon fiber (CF)‐reinforced polymer composites is a key factor affecting the overall performance of the material. In this work, we prepared a sulfonated poly(ether sulfone)–graphene oxide mixed sizing agent to modify the interface of CF/PEEK composites and improve the interfacial properties between the PEEK matrix and CF. Results showed that the mechanical and interfacial properties of CF/PEEK composites are improved by the sizing agent. Specifically, the flexural strength, flexural modulus and interlaminar shear strength of the materials reached 847.29 MPa, 63.77 GPa, and 73.17 MPa, respectively. Scanning electron microscopy confirmed markedly improved adhesion between the resin matrix and fibers. This work provides a simple and effective method for the preparation of high‐performance CF/PEEK composites, which can improve the performance of composites without degrading the mechanical property of pristine CF.

“…Recently, the group of Montáns [182,183] provided a series of extension of phenomenological linear theory, realizing the simulation of strain-stress relation and auxetic behaviour of auxetic foam through an accurate numerical methodology. Such methodology makes orthotropic materials not only feasible but also efficient (compared with FE analysis) simulated.…”

Research on auxetic metamaterials is important due to their high performance against impact loadings and their usefulness in actuators, among other applications. These metamaterials offer a negative Poisson’s ratio at the macro level. However, usual auxetic metamaterials face challenges in (1) grading the effect, (2) coupling and combining auxetic metamaterials with non-auxetic materials due to boundary compatibility, (3) obtaining the same auxetic behavior in all directions in the transverse plane, and (4) adapting the regular geometry to the component design boundary and shape. The goal of this paper is to present a novel, recently patented tunable 3D metamaterial created to reproduce a wide spectrum of 3D auxetic and non-auxetic Poisson’s ratios and Young’s moduli. This wide range is obtained using the same basic unit cell geometry and boundary connections with neighboring cells, facilitating designs using functionally graded metamaterials as only the connectivity and position of the cell’s internal nodes are modified. Based on simple spatial triangularization, the metamaterial is easily scalable and better accommodates spatial curvatures or boundaries by changing the locations of nodes and lengths of bars.
