Polymer construction materials in composite design achieve high strength, have high chemical and thermal resistance as well as resistance to UV radiation. Due to the fact that polymer composites are often used for a long time outdoors, they are exposed to the weather and living organisms. The polymer composite PA66 + GF30 was used in the experiment. The composite consists of a polyamide matrix (PA) and a short glass fiber. Samples of the composite were subjected to accelerated aging in a UV chamber under precisely defined conditions. After UV degradation, the samples were still exposed in wet soil. After exposure, the samples were evaluated for a change in weight and a change in absorption in boiling water. Changes in the surface topography of the samples were evaluated using a light microscope.
