The efficiency of elasticity characteristics prediction for the unidirectional polymer composite materials at high temperatures is investigated. The deformation of such materials at the elevated temperature is described using the linear model of mechanics of multiphase media. The mechanical properties of the ablating materials depend on the temperature and the heating rate. It is shown that the specific density of the unreinforced matrix, the bundle of polymer fibers and the unidirectional carbon fiber-reinforced plastics changes significantly at the elevated temperature. The comparison between the calculated elasticity characteristics of the ablating transversely isotropic materials and their experimental results is given.References
