Abstract

The climatic aging of aramid organic plastics in various natural environments is investigated. It is shown that the climatic stability of organic plastics is at the level of resistance of polymeric composite materials reinforced by carbon fibers and fiber glasses, despite the higher water absorption. Organic plastic Organit 10Т has 71 % of tensile strength properties after 18 years of climatic aging. Organic plastics can recover their properties after removal (drying) of the sorbed moisture. Organic plastics from new Rusar-NT fiber and epoxy melt binders have the biggest resistance to climatic aging.
