| Popis: | Nanocomposite cylinder can be exposed to the thermal and mechanical loading due to hot fluid that flows through them. In this manuscript, it is intended to get thermal and mechanical single-walled carbon nanotubes (SWCNTs)/glass fiber/epoxy nanocomposite cylinder properties by using micromechanical relations for different weight fractions (wt%). Also, using classical lamination theory, stress–strain and equilibrium equations and strain–displacement relations, the distribution of the radial, hoop and axial stresses and strains in the wall of the three-phase nanocomposite cylinder is obtained for different weight fractions (wt%) of SWCNTs and different lay-ups [35/− 35/90/90] and [55/55/− 55/− 55]. The results demonstrated that the addition of the SWCNTs to the epoxy can reduce all strains in the wall and also reduce the strain difference between two layers with different fiber angle. Also, the effect of reduction in axial and hoop stress depends on angle fiber of lay-up. |
