Basalt Fiber Civil Engineering Transportation Infrastructure Environmental Protection And Military Applications
Basalt Fiber Material is an advanced inorganic composite derived from natural volcanic basalt rock. Melted at 1,450–1,500°C and drawn into continuous filaments, it offers exceptional mechanical strength, thermal stability, and corrosion resistance. Key features:
Eco-Friendly: 100% natural, recyclable, and free of carcinogens
.Extreme Temperature Tolerance: Operates in -269°C to 800°C environments
.Chemical Resistance: Impervious to acids, alkalis, and solvents
.Lightweight: 20–30% lighter than fiberglass with equivalent strength
.Applications: Structural reinforcement, thermal insulation, automotive parts, aerospace components, and fireproof textiles
.Raw Material Processing:
Basalt rock is crushed and melted in a platinum-rhodium alloy furnace at 1,450–1,500°C
.Fiber Drawing:
Molten basalt is extruded through spinnerets to form 7–25 µm diameter filaments
.Textile Production:
Filaments are woven into unidirectional (UD), plain, twill, or satin fabrics using precision looms
.Surface Treatment:
Coated with sizing agents (e.g., silane) to enhance adhesion and UV resistance
.Quality Control:
ISO 9001-certified testing for tensile strength (3,800–4,800 MPa) and thermal stability
.Mechanical Handling:
Avoid sharp tools or excessive bending to prevent fiber breakage
.Chemical Exposure:
Resistant to most chemicals but avoid prolonged contact with strong oxidizers (e.g., concentrated sulfuric acid)
.Thermal Management:
Prevent rapid temperature shifts to avoid thermal shock cracking; use in dry conditions
.Storage:
Store in ventilated, dry areas; avoid folding under tension
