Abstract

The article is devoted to the study of mechanical characteristics and indicators of moisture transfer of monolithic and three-layer cellular samples based on carbon fiber VKU-30K.Р14535 in the initial state, after mechanical shock damage, after repair and full-scale climatic tests in a moderately warm climate. The problem of «sensitivity» of polymer composite material (PCM) to shock damage is highlighted. The results of research work on the study of the properties of a number of aircraft PCM with mechanical damage in different climatic conditions are noted.
