This article presents the results of the development and methodology for the selection of rational compositions of polymer and fiber concrete, providing physical and mechanical characteristics of new structural materials for the engineering industry. The novelty of these studies is the proof of the technical feasibility and economic feasibility of obtaining a new composite material that can be used in mechanical engineering in the manufacture of equipment for the mining and metallurgical complex. At the moment, composite materials such as polymer and fiber concrete are widely used in various industries. Studies have revealed that it is rational to use a filler with intermittent granulometry consisting of three fractions. At the same time, smaller fractions fill voids in larger fractions, which increases the density of polymer concrete and its strength. The influence of the main factors on the characteristics of polymer concretes is investigated: the rotation frequency of the mixer working body, the mixing time of the components and the temperature of the resin ED. The technology of mixing the components in two stages has been developed, which ensures the production of a homogeneous mixture and an isotropic material after curing. The conducted studies have confirmed that the use of these materials НАУКА И ТЕХНИКА КАЗАХСТАНА. ISSN 2788-8770. № 2, 2024 73 for body parts in mechanical engineering is not inferior in technical characteristics to traditional materials such as cast iron and aluminum alloys. The equipment used in mining enterprises and metallurgical plants is subjected to severe operating conditions, such as exposure to aggressive media, high dust content, sudden temperature changes, transportation of abrasive liquids, etc. In this regard, in the production of machine bodies and mechanisms, it is necessary to increase their thickness, which leads to excessive metal consumption, difficulties in maintenance and an increase in cost. Replacing traditional metals with composite materials with improved characteristics seems appropriate.DOI
