“…Due to the excellent electrical and thermal conductivity [6], high young's modulus [7], mechanical properties [8] and lower density [9], graphene is regarded as the ideal strengthening phase for the composites [10]. however, its large specific surface area and the van der Waals force between the graphene nanosheets give rise to agglomeration, which make it difficult to uniformly disperse on the metal matrix [11,12]. in addition, the poor interface bond between the graphene and the metal matrix hinders the development of graphene metal matrix composites [13][14][15].…”

Influence of copper powder Morphology on the MIcrostructure and propertIes of copper MatrIxBulk coMposItes reInforced wIth ni-doped graphene to clarify the effect of copper powder morphology on the microstructure and properties of copper matrix bulk composites reinforced with ni-doped graphene, spherical and dendritic copper powders were selected to fabricate the ni-doped graphene reinforced copper matrix bulk composites. the ni-doped graphene were synthesized by hydrothermal reduction method, followed by mixing with copper powders, and then consolidated by spark plasma sintering. it is found that the ni-doped graphene are well bonded with the dendritic copper powder, whereas ni-doped graphene are relatively independent on the spherical copper powder. the copper base bulk composite prepared by the dendritic copper powder has better properties than that prepared by spherical copper powder. at 0.5wt.% ni-doped graphene, the dendritic copper base bulk composite has a good combination of hardness, electrical conductivity and yield strength, which are 81.62 hV, 87.93% iaCS and 164 MPa, respectively.

“…Adding CNTs into polymer matrix of industrial composite materials resulted in an increase of elastic modulus and fracture toughness only for 0.1 weight percentage of CNTs 2. Dastjerdi et al 3 investigated the effects of nonlinear van der Waals forces on the bending analysis of orthotropic bilayer conical graphene panels. The energy method with first‐order shear deformation theory were used to obtain governing equations of the system.…”

In this study, the effect of carbon nano‐tubes (CNTs) and fiber carbons on vibration frequency of delaminated anti‐symmetric cross‐ply cylindrical shells is investigated. In this case, (CNTs) are added into polymer matrix of industrial composite. The mixture of rule and Halpin‐Tsai relation are used to obtain the effective materials of reinforced delaminated multi‐scale composite cylindrical shell. Based on Galerkine's method an approximate‐analytical solution is presented to predict the frequency vibration of delaminated multi‐scale composite shells. The results are used to assess the effect of various parameters including CNTs weight percentage, geometric parameters, delamination length and position across circumferential and thickness direction on frequency ratio for CNTs reinforced anti‐symmetric cross‐ply delaminated composite cylindrical shells.

“…To have good understanding from the behavior of these intelligent materials, various investigations and analyses should be conducted on them such as dynamics, vibrations, buckling, and bending (Ahmadian and Norris, 2008; Aissani et al, 2015; Akgöz and Civalek, 2017; Amar et al, 2017; Dastjerdi et al, 2018; Ebrahimi and Dabbagh, 2018; Ebrahimi et al, 2019; Karami et al, 2018; Occhiuzzi et al, 2003; Smelyanskiy et al, 2011; Taghizadeh et al, 2015; Yahia et al, 2015).…”

This study presents an investigation of the wave propagation of a rectangular sandwich composite plate with tunable magneto-rheological fluid core. The constituent parts of this rectangular sandwich composite plate are the base layer, magneto-rheological fluid core, and limiter layer. Magneto-rheological fluid core is embedded within the base and limiter layers. Also, the upper and lower layers are made of elastic materials. For obtaining the governing equations of motion, Hamilton’s principle and classical plate theory are used. After that, applying an analytical solution, the wave frequency and phase velocity of the propagated waves can be gained by solving eigenvalue problem. By investigating the effect of the magnetic field, the results emphasize that the magnetic field intensity is the most important factor for changing the value of the wave frequency and phase velocity. Besides, results show by enhancing the core-to-top layer thickness ratio, the wave frequencies reduce because magneto-rheological fluid core is softer in comparison to elastic layers. Therefore, magneto-rheological fluid layer operates similar to a damper. At the end, the influence of the thickness of magneto-rheological fluid core on the phase velocity is also discussed.
