Abstract

The climatic resistance of CFRP to influence of eight types of climate of different climatic zones during the three year exposition were investigated. Exposed polymer composite was studied by optical microscopy, dynamical mechanical analysis, moisture saturation, flexural strengthandcompressive strength of polymer composite were determined. Deterioration of upper layer of polymer matrices after exposition was shown. Relationship between climatic factors influence on polymer composites, changing of polymer matrices condition and decreasing of material strength was found.
