Abstract

The choice and substantiation of conditions of thermal aging of polymer composite materials intended for aviation components were described in the paper. Researches of changes in PCM strength at compression, interlayer shift and bending, and in glass-transition area and temperature were conducted at various test temperatures both in an initial state and after an impact of thermal aging. Conditions of thermal aging of materials and a strength characteristic most sensitive to temperature influence, i.e. strength at interlayer shift were defined by the results of research of a «strength/test temperatures» dependence and glass-transition area and temperature. Strength of polymer composite materials at interlayer shift was defined depending on temperature and exposition duration within the chosen conditions of thermal aging. An influence of some assumed operation temperatures and considerably higher temperatures was defined. An influence of temperature depending on the exposition duration w
