Abstract
In this work has been investigated the climatic resistance of carbon and fiberglass polymers for aviation purposes based on solvent-free binders VST-1208, VSE-1212, VSR-3M after 3 years of exposure of these materials in the moderate cold climate of Moscow and the moderate warm climate of Gelendzhik. The effect of destruction, post curing, plasticization of binders on the compressive and flexural strengths of carbon plastics VKU-27L, VKU-39, VKU-46 and fiberglass plastics VPS-47/7781, VPS-48/778 was determined using the methods of profilometry, moisture transfer and dynamic mechanical analysis. It is shown that while determining the state of PCM after climatic exposure, it is necessary to take into account the effects of the reversible plasticizing action of moisture. A comparison is made of the climatic resistance of the investigated materials.
