Carbon Tow/Yarn

Carbon tow (continuous fiber bundles) and carbon yarn (fine filament strands) are the foundational building blocks of high-performance composites. Engineered from polyacrylonitrile (PAN)-based carbon fibers, they offer exceptional tensile strength (3,000–7,000 MPa), high modulus (230–800 GPa), and low density (1.7–1.8 g/cm³), making them ideal for manufacturing lightweight, rigid composite materials.

Core Advantages

  • Superior Strength-to-Weight Ratio: 10x stronger than steel at 1/5 the weight; critical for weight-sensitive applications (aerospace, racing).
  • High Thermal Stability: Resists decomposition up to 3,000°C in inert environments; maintains rigidity at 200–300°C (continuous use).
  • Chemical & Corrosion Resistance: Unaffected by acids, alkalis, and solvents; ideal for marine, oil, and chemical processing industries.
  • Customizable Filament Counts: Available in 1K (1,000 filaments) to 48K (48,000 filaments) bundles for tailored strength and flexibility.
  • Enhanced Composite Performance: Improves structural integrity, impact resistance, and fatigue life when woven, braided, or laid up into composites.

Product Specifications

  • Filament Count (Tow Sizes): 1K, 3K, 6K, 12K, 24K, 48K (standard); custom counts available for bulk orders.
  • Fiber Grade: Standard Modulus (SM), Intermediate Modulus (IM), High Modulus (HM) – T300 to T1100 grades.
  • Linear Density: 100–2,000 tex (grams per 1,000 meters).
  • Surface Treatment: Sizing (epoxy, polyester, or nylon compatible) for improved resin adhesion; unsized options available.
  • Spool Packaging: 1–10 kg spools, 50–200 kg cones, or custom reels for automated manufacturing lines.

Key Applications

  • Composite Manufacturing: Prepreg fabrics, unidirectional tapes, and 3D printing filaments (FDM/AFP processes).
  • Aerospace & Defense: Aircraft wings, rocket motor casings, and satellite structures (reduces fuel consumption by 20–30%).
  • Automotive: Racing car chassis, EV battery enclosures, and lightweight body panels (improves energy efficiency).
  • Sports & Leisure: Golf shafts, tennis rackets, bicycle frames, and fishing rods (enhanced performance and durability).
  • Industrial: Wind turbine blades, pressure vessels, and high-stress machinery components (extends service life by 50%+).

Wholesale & Retail Solutions

Bulk Wholesale: Minimum order 50 kg (12K–48K tow); custom filament counts, sizing, and packaging available. Volume discounts for 500 kg+ orders (ideal for manufacturers).

Retail & R&D: Small spools (1–5 kg) for prototyping, education, and hobbyists. Sample kits (1K–6K tow) available for testing resin compatibility and process validation.

Quality & Compliance: ISO 9001/AS9100 certified production, full material traceability (from PAN precursor to finished tow), and test reports (tensile strength, modulus, elongation).
