We considered the problem of evaluating the durability of film-fabric material (FFCM). The models of phase deformation of a film-fabric composite material was developed which took into account nonlinear viscoelasticity, temperature changes, material aging, microdamage accumulation processes and photodestruction. We presented the composration as an inhomogeneous body. When choosing the structure of the defining relations, we used the experimental data obtained by the authors for the phases of FFCM. Based oite under considen the modification of the second Fick’s law, the kinetic law of propagation of the photodestruction parameter deep into the representative cell of FFCM was constructed. To conduct a qualitative analysis of the behavior of the composite material under study, we formulated the problem with some model constitutive relations and numerical experiments were performed.
