Abstract

Presentsthe  results of of research of the properties of a series of high-temperature carbon plastics based on phthalonitrile resin after long-term exposure in various climatic zones: temperate climate, moderately warm climate with mild winters, warm humid climate, very cold climate are presented. The state of the surface of carbon fiber reinforced plastics has been investigated, their thermal stability and water absorption have been determined. After exposure, CFRPs showed high retention of properties from the level of the initial values: 80–90% at room temperature of tests and 60–75% at a temperature of 300 °С.
