Basalt Fibre Comparison with Glass and Carbon Fibres
topic
Basalt fibre occupies the performance and cost space between E-glass and carbon fibre with tensile strength 30 to 40 percent higher than E-glass at 20 to 30 percent premium cost, elastic modulus 10 to 15 percent above E-glass, superior chemical and thermal resistance to E-glass, but tensile strength 30 to 40 percent below carbon fibre at one-fifth to one-tenth the cost, making property-cost trade-off analysis essential for application selection.
Role
Guides material selection decisions for composite reinforcement applications by quantifying the performance advantages of basalt over E-glass and the cost advantages over carbon fibre, identifying the application space where basalt provides the optimal balance of mechanical performance, thermal and chemical resistance, and cost for specific structural and functional requirements.
