The modeling of radiation characteristics of fibrous composites depending on a material, shape and volume content of fibers is carried out. For example, the effect of the external thermal radiation on the thermal state of the irradiated layer depending on its characteristics is investigated. The problems of determining the thermal and thermostressed states of a long double-layer hollow cylinder, located in the conditions of the asymptotic thermal regime, with incomplete information about the parameters of the thermal contact and additionally known radial displacements of one of the boundary surfaces are formulated. They are reduced to the inverse problems of thermoelasticity at finding the temperature. The stability of solutions to small errors in input data is investigated. The method of determination of axisymmetric stationary thermal and quasi-static stress and strain fields in the hollow multilayer thermosensitive cylinders is developed. The effect of the temperature dependence of the thermomechanical characteristics of the materials of infinite three-layered cylinder on the level and distribution of temperature and stresses therein is investigated.
