Abstract

A mathematical model was constructed describing the thermomechanical interaction of particles of the composite matrix and reinforcing elements (randomly oriented anisotropic single-walled carbon nanotubes) with an isotropic medium with the desired thermoelastic characteristics. This model was used to find the self-consistency of the thermoelastic characteristics of the composite, taking into account the porosity of its matrix, which are compared with two-sided estimates derived from the dual variational formulation of the thermoelasticity problem. The presented relations make it possible to estimate the effect of the porosity of the matrix of the composite under consideration on its thermoelastic characteristics.
