Industrial Carbon Fiber Cloth

Tow: 6k – 24k Width: up to 1600 mm Areal weight: 300 – 900 g/m²

Industrial Carbon Fiber Cloth is engineered for high-throughput manufacturing and heavy-load structural applications. Utilizing larger tow counts (6k, 12k, 24k) and coarser weave patterns, this fabric delivers a cost-effective solution for parts requiring substantial thickness build-up and high fiber volume fractions. The cloth is available in plain, twill, and unidirectional (UD) variants, with areal weights ranging from 300 g/m² to 900 g/m². The open tow structure allows rapid resin impregnation in infusion, compression molding, and pultrusion processes, making it suitable for construction, marine, wind energy, and heavy transport sectors.

Industrial Applications

Wind turbine blades

Spar caps, shear webs, and root sections requiring high fatigue resistance and thickness build-up.

Marine structures

Hull reinforcements, bulkheads, deck panels, and stringers for large vessels and workboats.

Construction & civil

Bridge strengthening, seismic retrofitting, concrete reinforcement, and structural repair wraps.

Heavy transport

Railcar body panels, truck chassis components, and container floor reinforcements.

Oil & gas

Pipe wraps, offshore platform components, and corrosion-resistant cladding systems.

Pultrusion profiles

Continuous rods, tubes, and structural sections for high-volume industrial production.

Strength & Build

900 g/m² Max areal weight
1.35 mm Max thickness per ply
1600 mm Max roll width
Heavy-tow cloth reduces layup time by 60% compared to 3k fabrics for equivalent laminate thickness.

Processing Guide

  • Infusion: Use medium-viscosity resins (400–800 cP) with inlet pressure ≤ 2 bar to achieve complete wet-out without tow displacement.
  • Compression molding: Pre-heat mold to 120–140 °C; apply 10–15 bar pressure for 5–10 minutes per mm thickness.
  • Pultrusion: Resin bath temperature 40–60 °C; line speed 0.3–0.8 m/min depending on profile cross-section.
  • Hand layup: Use serrated rollers to remove entrapped air; apply 0.5–0.7 bar vacuum bag pressure.
  • Cutting: Water-jet or abrasive cutter recommended; avoid fiber pull-out by supporting edges.

Technical Q&A

How does tow size affect fabric handling?

Larger tows (12k, 24k) reduce flexibility compared to 3k fabrics. Use twill or satin weaves for improved drapability over curved surfaces. For flat panels, plain weave provides superior stability and dimensional control.

What is the recommended ply thickness for industrial laminates?

Target cured ply thickness is 0.45–0.55 mm for 300 g/m², 0.65–0.75 mm for 600 g/m², and 1.0–1.2 mm for 900 g/m², depending on resin content and compaction pressure.

Can this cloth be used in outdoor / UV-exposed environments?

Yes. Pair with UV-stable resin systems (e.g., vinyl ester or acrylic-modified epoxy) and apply a protective gelcoat or topcoat for long-term durability in marine and outdoor applications.

What is the shelf life of industrial carbon cloth?

18 months from date of manufacture when stored in original moisture-barrier packaging at 15–28 °C and ≤ 60% RH. Sizing activity declines gradually; perform a wet-out test prior to use after 12 months.
