Development of Construction and Repair Materials Used in Transport and Technological Machines Operating in the Arctic

Abstract

Increasing the pace of development of the Arctic zone, among other tasks, requires the attraction of significant production resources to improve the transport network, in particular, road construction equipment and technological equipment. Extreme climatic conditions, including low air temperatures and strong winds, are features of the Arctic zone. In this regard, there is a need to form a methodological basis for the development of construction and repair materials for use in the Arctic. To solve this problem, based on the results of mechanical tests at temperatures of +20°C, -30°C and -50°C, the possibility of using carbon fiber plastics with various types of hybrid matrices for the manufacture of mechanical engineering products operating in extreme conditions of the Arctic and the creation of reinforcing linings during their repair. The indicators of manufacturability during repairs under the conditions of constant exposure to negative temperatures using polymeric materials are considered.
