12K 0.126MM 230G Unidirectional Carbon Fiber Fabric

230g carbon fiber fabric (unidirectional CFRP) is the widely used, cost-effective, and reliable material for structural strengthening and seismic retrofitting worldwide.

Lightweight, ultra-high-strength, corrosion-resistant, and easy to install, it is applied to concrete, masonry, wood, and steel structures to significantly improve flexural capacity, shear resistance, crack control, and durability.

What is 230g Carbon Fiber Fabric?

• 230g/m² = standard areal weight

• Unidirectional (UD) – fibers aligned in one direction for maximum tensile strength

• Thickness: approx. 0.128 mm per layer

• Material: 12K  PAN-based high-performance carbon fiber

• Used with two-part epoxy impregnation resin to form a high-strength composite system

Key Mechanical Properties (International Standards)

Core Advantages for Projects

✅ Ultra-Lightweight – does not increase structural self-weight

✅ Corrosion & Acid Resistance – perfect for coastal, industrial, and marine environments

✅ Fast Construction – reduces downtime; suitable for occupied buildings

✅ Flexible – easily wraps columns, beams, and curved surfaces

✅ Long Service Life – over 50 years with proper protection

✅ Non-Magnetic – ideal for hospitals, labs, and data centers

Main Applications 

230g carbon fiber is used in all types of structural repair and strengthening:

✔ Building & Commercial Structures

International Compliance & Quality

Our 230g carbon fiber systems comply with major international design and test standards:

ACI 440 (USA)

fib TG9.3 / Eurocode (Europe)

JIS (Japan)

ISO 10406

GB 50367 (Chinese standard, widely recognized globally)

Standard Installation Process (Simple & Efficient)

• Surface preparation (concrete grinding, repair, rounding corners)

• Apply epoxy primer

• Mix and apply impregnation resin

• Paste carbon fiber fabric

• Roll to remove air bubbles and ensure full saturation

• Apply top impregnation epoxy again

• Cure and protect

Quality Control & Inspection

• Full bond area ≥ 95%

• No hollow spots, wrinkles, or edge lifting

• Pull-off bond strength test ≥ 2.5 MPa
