The results of experimental investigations of unidirectional composites based on basalt fibers and an epoxy resin are presented. Uniaxial tensile tests at increased operation temperatures were carried out using a specimen fixation technique imitating the operation conditions of structures. The mechanical properties at temperatures of 50, 70, 80, 90, 100, 110, and 120°С and the coefficient of linear thermal expansion in the temperature range from 25 to 150°С of the basalt-fiber-reinforced plastic (BFRP) were determined. The effects of a preliminary thermal cycling and thermal aging on the static mechanical properties of the BFRP are analyzed. The temperature dependences and deformation diagrams of BFRP specimens are obtain.
