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.
