In construction there is increased interest in using basalt fibers as an alternative to traditional polymer composite materials based on glass, organic fibers, or carbon fibers. In this respect, new information revealing the possibilities of basalt plastic materials as construction materials is of interest. In this paper, the influence of the type of filler on the physical and mechanical properties of basalt-textolite and fiberglass is studied. A description of composites based on basalt fiber and fiberglass and the production of basalt continuous fiber is given.
