its remarkably high mechanical properties (strength ∼ 30 GPa and modulus ∼ 900 GPa [ 128 ] ), comparable to those of CNTs, and superior thermal stability.

Mathematical modelling of microtubule-tau protein transients: Insights into the superior mechanical behavior of axon

“…It can be noted from Eq. (9) that, the micromechanical interaction behavior of axon is determined by (LC/ζ) 2 Experimental data from numerous researches are applied to assign values to the parameters in viscoelastic SLM [9,16,17,41,[44][45][46][47][48][49]. The length of MT is about 1-10 μm, and its outer and inner diameters are 25 nm and 14 nm, respectively [9].…”

“…Staggered biocomposites are found to exhibit a remarkable mechanical balance of fracture toughness versus stiffness and strength [1,2]. In consideration of the structure of staggered biocomposite and the vulnerability of axon, it may possess the innate ability of mechanical balance of high stiffness and high toughness, and self-protecting over the course of evolution; hence the axon is taken as an example for investigation in this study.…”

Nanoscale Mechanical Characterization of 1D and 2D Materials with Application to Nanocomposites

“…Dynamic mechanical analysis (DMA) is another experimental technique that has been used to study the mechanical behavior of carbon nanostructure-based composite materials (Compton et al 2010Yang et al 2004;Zou et al 2004;Wang et al 2004;Espinosa et al 2012b;An et al 2011). While DMA has been extensively used to measure the viscoelastic response of CNT-polymer and CNTepoxy matrix nanocomposites as it measures both the storage and loss moduli (Yang et al 2004;Zou et al 2004;Wang et al 2004;Espinosa et al 2012b), it can also be used to indirectly study the shear interactions within other forms of carbon-based nanocomposites.…”

An et al used DMA to measure the stiffening effects of bio-inspired composite GO papers which were similar to borate cross-linkers.…”

Avaliação das propriedades de oxirredução e reforço mecânico de materiais híbridos baseados em nanotubos de carbono sobre suportes microestruturados

“…Exemplos de tais estruturas são os ossos e tendões de mamíferos, o nacre de conchas e as teias das aranhas, todos com alguma função de sustentação, de proteção ou outros mecanismos de sobrevivência. 6 A biônica é um ramo da ciência de materiais que se baseia no desenvolvimento de materiais de engenharia a partir de materiais naturais.…”
