Abstract

Problem statement. To prove that it is possible and feasible to use polymer concrete and fiber concrete as structural materials in mechanical engineering for manufacturing gearbox and centrifugal pump housings. Methods applied. When carrying out the research, we used theoretical studies with an experimental verification of their results in laboratory conditions, methods of the rational planning of experiments with a statistical processing of results, and bench tests of equipment samples. The novelty of the research is to justify the possibility and feasibility of using polymer concrete and fiber concrete as structural materials for mechanical engineering. Results. As a result of the research, for the first time the authors developed the methods for designing rational compositions of mixtures with a discontinuous granulometry of aggregates for the production of polymer concrete and fiber concrete and the technology for preparing mixtures and casting finished products. The paper describes how fundamental factors influenced the strength of polymer concrete and fiber concrete, which allowed us to develop a two-stage technology for manufacturing gearbox and centrifugal pump housings with a high degree of readiness, not requiring an additional processing. The results of theoretical and laboratory studies were verified during bench tests of manufactured samples of the TS2-250 gearbox with a polymer concrete body and the 4K6 centrifugal pump made of fiber concrete. These tests proved a number of advantages over metal products. Practical relevance. We have studied the behavior patterns of new structural materials (polymer concrete and fiber concrete) and recommend them as efficient structural materials to be used in machinery to manufacture some machines and mechanisms that will have several advantages: high strength, ability to work under rough conditions (corrosive environment, high dust levels, working with highly abrasive materials, etc.), weighing 2–2.5 times less than metal products, high technological efficiency of manufacturing products and a lower cost (by 18–20%).
