In mechanical terms, nanocomposites differ from conventional composite materials due to the exceptionally high surface to volume ratio of the reinforcing phase and/or its exceptionally high aspect ratio. The reinforcing material can be made up of particles (e.g. minerals), sheets (e.g. exfoliated clay stacks) or fibres (e.g. carbon nanotubes or electrospun fibres). The area of the interface bet...

CuO nanosheets (NSs)/reduced graphene oxide (rGO) hybrid lamellar films were prepared by vacuum filtration of CuO NSs/GO composite dispersions, followed by hydrothermal reduction. The CuO NSs/GO composite dispersions were assembled electrostatically by mixing a negatively charged GO sheets aqueous solution with a positively charged CuO NSs aqueous dispersion at room temperature. The prepared Cu...

The electrical properties of solution-processed composite thin films consisting of functionalized graphene sheets (FGS) as the filler and polystyrene (PS) as the host material are described. We demonstrate that transistors from graphene-based composite thin films exhibit ambipolar field effect characteristics, suggesting transport via percolation among FGS in the insulating PS matrix. Device ch...

Abstract The finite element simulation was performed for 8 carbon fiber reinforced plastic (CFRP) sheets steel-concrete composite beams via ABAQUS software, in an effort to further investigate their mechanical properties. Next, the influences of shear connection degree and elasticity modulus, width constitutive relation CFRP on properties were studied. Subsequently, load-dependent change laws m...

Abstract The composite sheet layup process involves stacking several layers of a viscoelastic prepreg and curing the laminate to manufacture component. Demands for automating functional tasks in manufacturing processes have dramatically increased past decade. A simulation system representing digital twin can aid development such an autonomous layup. While finite element analysis (FEA) is popula...

the accumulative roll bonding process is used as a severe plastic deformation technique to produce aluminum composite sheets with ultra fine structure. in this study the effect of simultaneous use mg and sic particles as reinforcements, on the tensile properties of the al-mg-sic hybrid compositeis studied. the al-mg-sic hybrid composites with different amounts of mg and sic contents were fabric...
