The gradual shift of oil and gas production enterprises to the north-eastern regions of the country, characterized by extremely low temperatures, high humidity and seismicity, requires additional analysis of the possibility of using polymer composite materials (PCM) in building structures, devices and apparatus used in field development. Materials, usually used in conditions of static loading, can experience additional dynamic loads in case of seismic effects. In this work, the results of the research of the influence of external environmental impacts in this region on three most common PCMs based on polybutylene terephthalate, polyamide and polycarbonate are presented. Tests of impact toughness of PCMs in the temperature range from +20 to –60℃ and after intensive water absorption were carried out.
