The tests were carried out after holding the samples at temperatures of 20±2 °C, –30 °C and –50 °C according to the Charpy method with the direction of an impact perpendicular to the plane. The use of an anaerobic polymer material as a component of the liquid phase of the hybrid matrix makes possible to obtain the highest impact strength among the compared types of carbon plastics and to ensure the stability of this characteristic after exposure at a temperature of –50°C. Synthetic wax in the structure of the composite matrix ensures the stability of impact strength after storage at a temperature of –30°C.
