Carbon Fiber Tow (industrial grade)

Description

1. Key Specifications & Technical Characteristics

• Material composition: PAN-based carbon fiber precursor, surface-sized with epoxy-compatible sizing agent

• Grade: Industrial standard (non-aerospace prime) – 12K, 24K, 50K tow formats

• Physical characteristics: Continuous black filament tow; density 1.78–1.80 g/cm³; tensile strength ≥3.5 GPa; tensile modulus 230–240 GPa

• Packaging options: Non-returnable cardboard spools (4–10 kg net), steel flanged spools (15–20 kg), or bulk drum winding (up to 100 kg)

• Shelf life: 24 months in original, unopened packaging stored at 15–30°C and <60% RH

2. Core Industrial Applications

• Wind energy: Spar caps and shear webs for blades >50m – outperforms glass fiber with 40% lower laminate thickness for equal stiffness

• Automotive structural parts: Compression-molded battery enclosures and leaf springs – enables 50% part weight reduction vs. high-strength steel

• Oil & gas: Continuous filament-wound pressure vessels and downhole tooling – resists H₂S embrittlement where e-glass fails within 6 months

• Construction: Concrete reinforcement grids and seismic retrofits – non-corrosive, eliminating rebar spalling life-cycle costs

3. Competitive Advantages

• Quality consistency: In-line tow tension monitoring with ±1% CV per 1,000m – traceable to production shift and precursor batch.

• Supply reliability: Dual-continent production (Asia + Europe) with safety stock warehoused in NA, EU, and GCC.

• Logistics capability: Direct container loading from mill to port; demurrage risk transferred to seller under CIF terms.

• Price competitiveness: 12–18% below EU/US spot prices for equivalent 50K tow, locked via quarterly index-linked contracts.

• Sustainability: Mass-balance certified recycled carbon fiber content available upon request (30% post-industrial).

• Technical support: On-site winding and impregnation troubleshooting via remote AR tools or 72-hour engineer dispatch.

4. Commercial & Supply Information

• Minimum order quantity (MOQ): One metric ton (MT) per tow size

• Bulk loading capacity: 20 MT per 20-ft container (spooled), or 24 MT per 20-ft for drum-wound tows
