Polymer composite materials are increasingly used as materials in aircraft, auto and shipbuilding, in the construction of buildings and structures. due to their light weight, high strength and durability. To replace carbon fiber, basalt and glass fibers are increasingly used as reinforcing fillers. In this paper, samples of basalt and fiberglass based on epoxy resin, obtained by vacuum infusion, were studied for cyclic loading with a uniaxial increasing load "tension-compression". According to the results of the tests, the average strength values were obtained: for samples of basalt-paste, this value was 182.56 MPa, for fiberglass – 179.26 MPa. The tests carried out showed the effectiveness of this method and the validity for determining the resource characteristics of materials.

An urgent task in the production of polymer composite materials is to increase the elastic-strength properties by adding various modifiers, using various polymer matrices and formulations, changing reinforcing fillers and combining them. The last method is the most interesting. As the literature analysis of modern scientific works has shown, with this method there is a synergistic effect of increasing the strength of the material and reliability under various types of load. This paper presents the comparative results of tensile and bending tests on original hybrid, pure, and modified basalt, glass, and carbon plastics. The combination of basalt and glass fibers with carbon fiber, which has high rigidity, made it possible to increase the tensile strength to 9,5% and 9,3%, respectively, and to 39,5% and 2,6%, respectively, for bending.
