Basalt Fiber Woven Fabrics Continuous basalt fiber ( 12K - 24K ) Woven geotextile Structural reinforcement​

​​1. Product Introduction​​

Basalt Fiber Woven Fabrics are advanced composite materials engineered from continuous basalt filaments, derived from natural volcanic basalt rock. These fabrics exhibit exceptional thermal stability (operating range: -260°C to 800°C), superior chemical resistance (acid/alkali/UV tolerance), and lightweight durability (20-30% lighter than fiberglass with equivalent strength). Key applications include:

• ​​Construction​​: Reinforcement for concrete structures, tunnel linings, and seismic retrofitting

  .

• ​​Transportation​​: Automotive/aviation components (e.g., interior panels, engine mounts) to reduce weight and enhance fuel efficiency

  .

• ​​Industrial​​: Fireproof curtains, insulation for pipelines, and electromagnetic shielding

  .

• ​​Aerospace​​: Lunar mission materials (e.g., China’s Chang’e-6 probe flag) due to extreme temperature resilience

  .

​​2. Manufacturing Process​​

1. ​​Raw Material Processing​​:

   • Basalt rock is crushed and melted at 1,450–1,500°C using platinum-rhodium alloy bushings to produce continuous fibers (diameter: 5–25 µm)

     .

2. ​​Weaving​​:

   • Fibers are woven into plain, twill, or satin patterns using high-precision looms, adjustable for widths (1–3 m) and weights (100–2,126 g/m²)

     .

3. ​​Surface Treatment​​:

   • Coated with silane or sizing agents to improve adhesion, UV resistance, and flexibility

     .

4. ​​Quality Control​​:

   • ISO 9001-certified testing for tensile strength (3,000–4,800 MPa), thermal stability, and corrosion resistance

     .

​​3. Usage Precautions​​

• ​​Mechanical Handling​​:

  • Avoid sharp tools or excessive bending during installation to prevent fiber breakage.

• ​​Chemical Exposure​​:

  • Resistant to most acids/alkalis 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 to prevent creasing.

• ​​Emergency Measures​​:

  • If damaged, cut damaged sections and splice using high-temperature adhesive or replace entire panels.
