ABSTRACT
During incubation of polymer composite materials in soils it was revealed that the structure of composite materials, unsoundness, physical, and mechanical properties have changed. The replacement of microorganisms groups with each other in time in the layer bordering to the composite materials was displayed. Durability of composite materials decreases with increasing surface and volumetric unsoundness of the samples, occurring after incubation in soils. The selectivity of microorganisms’ impact on polymer composites was disclosed. The mechanism of fracture of composite materials was suggested.
