300gsm Carbon Fiber Fabric for Structural Strengthening

300gsm carbon fiber fabric is one of the most commonly used specifications in structural strengthening and concrete reinforcement projects. With a balanced combination of high tensile strength, suitable thickness, and easy on-site installation, it is widely used for building reinforcement, bridge strengthening, beam repair, column wrapping, and seismic retrofitting.

Compared with heavier fabrics, 300gsm carbon fiber fabric provides strong reinforcement performance while remaining flexible and easy to apply. It is an efficient CFRP material solution for engineers, contractors, and distributors involved in structural repair and rehabilitation projects.

What Is 300gsm Carbon Fiber Fabric?

300gsm carbon fiber fabric refers to carbon fiber fabric with an areal weight of 300 g/m². In structural strengthening applications, it is usually supplied in roll form and used together with epoxy resin to form a CFRP reinforcement system.

After bonding to the concrete or structural surface, the carbon fiber fabric helps improve tensile performance, flexural capacity, shear resistance, and overall durability of the structure.

It is commonly used for:

  • concrete beams
  • concrete slabs
  • columns
  • bridge structures
  • tunnels
  • industrial buildings
  • seismic strengthening projects

Applications of 300gsm Carbon Fiber Fabric

Concrete Beam Strengthening

300gsm carbon fiber fabric is often bonded to the tension zone of reinforced concrete beams to improve flexural capacity and reduce cracking. It is suitable for building renovation, load upgrading, and structural repair projects.

Slab Reinforcement

For concrete slabs and floor systems, 300gsm CFRP fabric can help improve load-bearing performance without adding significant dead weight to the structure.

Bridge Strengthening

In bridge repair projects, carbon fiber fabric is used for strengthening girders, piers, decks, and other structural elements. Its corrosion resistance and lightweight properties make it suitable for long-term infrastructure rehabilitation.

Column Wrapping

When wrapped around concrete columns, carbon fiber fabric can improve confinement, ductility, and seismic performance. This is especially useful in earthquake-resistant strengthening projects.

Industrial Building Repair

300gsm carbon fiber fabric is also suitable for factories, warehouses, power plants, and other industrial structures requiring structural rehabilitation or reinforcement.
