The study of the degradation of flat extended elements made of polymer composite material reinforced with glass fiber has been carried out. The stresses in the elements exposed to UV radiation were determined to assess the long-term strength by the level of permanent deformations. The dependence of the strength of the composite element on the degree and time of irradiation is offered. Based on experimental data on the residual strength of specimens subjected to buckling and UV irradiation, a relation is proposed that reflects the change in the strength of the test material on the stress level, irradiation power, and exposure time of these factors. A comparison of the experimental and calculated values of the breaking loads was carried out, which showed the consistency of the results. A linear relationship was established with short exposure time.
