“…FG-CNTRC can be named a novel sub-branch of the composite which is fabricated and brought into play in many engineering performances in recent years. These innovative materials are the outcome of reinforcing the nanofibers with carbon in the ultra-small scale, distributed smoothly and continuously in a polymeric matrix [4]. Shen [5] can be called one of the first researcher who analyzed the mechanical features of FGCNTRC then published an article in 2009 which examined the large deflection of FG-CNTRC in thermal environment.…”

In this work, large deflection behavior of a functionally graded carbon nanotube reinforced composite (FG-CNTRC) cylindrical shell under internal pressure is studied. The composite cylindrical shell reinforced along the longitudinal direction and made from a polymeric matrix. Based on first-order shear deformation shell theory (FSDT) and von Kármán geometrical nonlinearity, the set of governing equations are derived. Using the dynamic relaxation (DR) technique, these systems of equations are solved for various boundary conditions and the roles of volume fraction of CNTs, CNTs distributions and geometrical ratios are examined on the responses.

“…Moreover, according to the modified Halpin–Tsai model [ 32 ], E D 0( B 0) can be expressed as:

in which E GPL and E M are the Young’s modulus of GPLs and the matrix, respectively. The geometry factors ξ lD ( lB ) and ξ wD ( wB ) of GPLs in the disk and blades are given as:

where l D ( B ) , w D ( B ) , and t D ( B ) are the GPL’s average length, width, and thickness in the disk and blades, respectively.…”

This paper presents, for the first time, the mechanical model and theoretical analysis of free vibration of a spinning functionally graded graphene nanoplatelets reinforced composite (FG-GPLRC) porous double-bladed disk system. The nanocomposite rotor is made of porous metal matrix and graphene nanoplatelet (GPL) reinforcement material with different porosity and nanofillers distributions. The effective material properties of the system are graded in a layer-wise manner along the thickness directions of the blade and disk. Considering the gyroscopic effect, the coupled model of the double-bladed disk system is established based on Euler–Bernoulli beam theory for the blade and Kirchhoff’s plate theory for the disk. The governing equations of motion are derived by employing the Lagrange’s equation and then solved by employing the substructure mode synthesis method and the assumed modes method. A comprehensive parametric analysis is conducted to examine the effects of the distribution pattern, weight fraction, length-to-thickness ratio, and length-to-width ratio of graphene nanoplatelets, porosity distribution pattern, porosity coefficient, spinning speed, blade length, and disk inner radius on the free vibration characteristics of the FG-GPLRC double-bladed disk system.

“…Zhao et al [14] have summarized different modified theoretical models including the rule of mixture, Halpin-Tsai model, Mori-Tanaka model and other micro-mechanics models to predict the properties of GO reinforced polymer-based composites. It is assumed that the properties of the composites are behaved linear-elastically subject to loading.…”

Graphene and its associated compounds have been identified as extraordinary structural nano-fillers that can tailor the properties of new polymer-based composites with specific functionalities. Graphene possesses perfect 2D atomic architecture and has a large surface area that enhances the bonding, with tailored functional groups on its surface with polymer chains to form high strength composites. Recently, a lot of research has focused on developing composites with high specific strength, high electrical and thermal conductivities, high impact resistance, excellent energy storage capability and ability to maintain their strength at low-temperature environments by using graphene, graphene oxide (GO), reduced graphene oxide (rGO) or carbon nanotube/graphene. Ultimate goals are to design composites that can meet specific requirements for different engineering applications. In this paper, the discussion on all aspects in relation to the use of graphene and its associated compounds for advanced composites will be given in detail. The potentiality of using these materials for hightech applications will be explored. Up to date, it has been proved that the use of graphene-based nanofillers does improve the mechanical, interfacial bonding, electrical, thermal and electromagnetic interference shield properties of polymer-based materials. Appropriately adding a small amount of these nanofillers do make a big difference to the properties of host materials.
