Modern Basalt Fibrous Materials and Basalt Fiber-Based Polymeric Composites

The data presented characterize modern continuous basalt rovings as a novel type of silicate fiber having improved acid and alkali resistance, the strength level close to the well-known E-fibers, and improved elasticity modulus typical of high-modulus and high-strength magnesium aluminosilicate S-fibers. Mechanical properties of epoxy basaltoplastics are similar to the properties of S-glass fiber-reinforced plastics and greater than those of E-glass fiber-reinforced plastics. The alkali resistance and heat/humidity resistance of epoxy basaltoplastics are much greater than those of epoxy composites derived from E- and S-glass fibers, which is associated with the specificity of adhesive properties of basalt rovings.
