Basalt Fibre Reinforced Polymer Composites
topic
Basalt fibre reinforced polymer composites using epoxy, vinyl ester, and polypropylene matrices achieve tensile strength of 600 to 900 megapascals and flexural modulus of 30 to 45 gigapascals in aligned fibre laminates, with superior impact energy absorption compared to E-glass composites attributed to the higher fibre elongation at break and better fibre-matrix interfacial adhesion from basalt surface chemistry.
Role
Positions basalt fibre composites as a cost-competitive alternative to E-glass composites for marine hulls, bridge deck panels, pressure pipes, and automotive structural components where improved chemical resistance, better impact performance, or perceived environmental advantages of natural mineral origin justify small price premium over commodity E-glass reinforcement.
