“…Apart from the platelet aspect ratio, the platelet concentration is another important factor that affects the final properties of composites greatly. [39][40][41] Figure 6 shows the synergistic effect of platelet volume fraction and platelet aspect ratio on SPRCs' dynamic moduli. As expected, the storage modulus increases remarkably with the increase of platelet aspect ratio and its volume fraction simultaneously.…”

Load‐bearing biological staggered composites, like nacre, teeth, and bone, possess an exceptional combination of material properties like high stiffness and high toughness. To date, most of the analytical research are for nacre‐like bio‐inspired staggered composites, with highly overlapped platelets. But the collagen fibril‐like staggered composites, with slender or barely overlapped platelets, are out of their scope. This motivates this work. In this paper, based on the previous research, according to the elastic‐viscoelastic corresponding principle, an analytical model for dynamic properties of general bio‐inspired staggered composites is presented. Moreover, the effect of loading frequency in a wide range is studied. The accuracy of the model is verified by comparison with existing models and finite element simulations. Besides, parametric analyses and sensitivity analysis are conducted thoroughly. The results reveal that besides the platelet concentration and the platelet aspect ratio, the platelet overlap ratio also influences the damping behavior of bio‐inspired staggered composites to a certain extent; for biological/biomimetic composites with a larger overlap ratio, higher loss modulus is possible to be achieved, and the optimal aspect ratio is mostly within [5, 30]. These findings are of great significance to the optimal design of bio‐inspired engineering materials in the future.

“…The results revealed significant reduction in maximum transverse displacements and the transverse shear stresses in the core medium in the FFRC laminate beam compared to normal CFRP beam. Rao et al 156 used the bridging mechanics model by Huang to estimate the effective elastic properties of CNT‐grafted carbon fiber composites. They carried out two‐step homogenization where micro scale involved modeling of CNT/polymer interface, and mesoscale modeling was composed of three phases that is, fiber, fuzzy interface, and matrix.…”

This paper aims to explore the potential of carbon nanotubes (CNTs) in enhancing the structural capability and multifunctionality of carbon fiber composites in aerospace applications, primarily by focusing on interfacial applications. The conventional method of dispersing CNTs in a matrix is not fully efficient in exploiting the mechanical and multifunctional performance of CNTs. Hence, the use of CNTs at the interface or as a coating on the surface of carbon fibers has been suggested as a means of achieving multifunctionality, in addition to enhanced mechanical performance. The paper presents an overview of the various processes for growing CNTs on carbon fiber surfaces and examines the effects of CNT geometry and growth parameters on the properties of grafted fibers and their composites. Furthermore, it discusses the potential improvements in thermal and electrical conductivity achievable by incorporating CNTs at the interface, as well as the benefits of using CNTs as a sizing layer for carbon fibers, including enhanced fracture toughness and resistance to delamination.Highlights Comprehensive study of interface engineering in carbon fibers and Carbon Fibre Reinforced Plastic (CFRPs) using carbon nanotubes (CNTs). Improved transverse mechanical properties and overall thermal and electrical properties. Multifunctional applications possible with the use of CNT. Both experimental and numerical studies reviewed.

“…The potential advantages obtained from the use of composites with enhanced fibers have fostered a tremendous interest in understanding the mechanical, thermal, and electric properties of such composites (Aravand et al, 2016; Aziz et al, 2015). Not only many experiments have been conducted in the literature in an effort of improving interphase behavior through fuzzy fiber technology (Aziz et al, 2015; Li et al, 2015; Qian et al, 2010; Yildiz et al, 2020), but also a few theoretical models are available to understand the micro/nanomechanics behaviors of fuzzy fiber composites, namely elastic (Chatzigeorgiou et al, 2011, 2012; Lurie et al, 2018; Rao et al, 2021); elastic-plastic (Chatzigeorgiou et al, 2020; Chen et al, 2021); thermoelastic (Kundalwal and Ray, 2014); electromechanical (Dhala and Ray, 2015; Kundalwal et al, 2013). From the modeling point of view, the fuzzy fiber microstructures can be regarded as hierarchically reinforcing materials.…”

Fuzzy fibers are fibers enhanced in terms of multiphysics properties with radially oriented carbon nanotubes grown on their surface through the chemical deposition process. For the first time, this paper attempts to present two generalized zeroth-order asymptotic homogenization schemes aimed at identifying the homogenized and local response of fuzzy fiber-reinforced composites, accounting for both multiphysics piezoelectric effect and cylindrically orthotropic material behavior. The unit cell problems are solved using the multiphysics finite-volume and the multiphysics finite-element techniques, respectively. While the former approach is based on the strong form solution of the equilibrium and conservation equations in an averaged sense in the discretized domain, the latter is based on the minimization of the total potential energy over the entire unit cell. A recursive multiscale analysis algorithm is developed wherein homogenized moduli (or local fields) obtained from the homogenization (or localization) analysis at one scale are utilized in the calculation of homogenized moduli (or local fields) at the next scale. Numerical examples indicate that good agreement of the homogenized properties and local field distributions generated by the two approaches is observed hence confirming the accuracy of the new homogenization methods for fuzzy fiber composites with multiphysics behaviors.
