https://doi.org/10.22349/1994-6716-2018-96-4-170-184
Abstract
The paper describes results of microstructural and fractographic research of fracture features for epoxy carbon-fiber-reinforced plastics under static bend and compression load after long (till 5 years) climatic aging in different climatic zones of Russia (industrial zone of temperate climate of Moscow – MTsKI; temperate warm climate of Gelendzhik – GTsKI; warm humid climate of Sochi – GNIP, Russian Academy of Sciences). Changes of microstructure and main types of destruction in the volume of carbon fiber reinforced plastics have been established. It is shown that changes of structure and torsion nature of fracture in volume epoxy carbon-fiber-reinforced plastics are typical for all zones of climatic aging and are defined by processes of complex manifestation of mechanical stresses and chemical destruction of materials.
