Carbon Fiber Fabric for Structural Reinforcement

ACF Carbon Fiber Fabric is made of high-strength and high-modulus 12K tow with continuous carbon fibers in a certain direction. It has light weight, flexibility, and good strength performances, suitable for reinforcing and repairing various structural parts and types, including beams, plates, columns, roof trusses, piers, bridges, cylinders, shells, and other structures.

ACF is applied together with the special ASR-300 Impregnating Adhesive, which fully infiltrates the carbon fiber cloth, ensures great bonding, and protects the composite layer from various adverse environmental factors.

Uses

Bending and shear reinforcement of concrete beams
Bending reinforcement of plates
Seismic reinforcement of columns
Reinforcement of factory buildings, buildings, school buildings, hospitals and other industrial and civil buildings
Reinforcement of roads and bridges, water conservancy, nuclear power, energy and other infrastructures

Advantages

High humidity aging resistance, freezing and thawing resistance, long-term stress resistance and fatigue stress resistance
High acid and alkali resistance, salt fog resistance, seawater immersion resistance, free from chemical corrosion and harsh environment, and pollution-free
Light self-weight, with the density of one-fifth of steel material, convenient and quick construction, no structural load added
High strength, able to meet the reinforcement of various structures such as bending and shearing of different concrete members
Good flexibility, suitable for beams, columns, plates, pipes, walls and other structures of various shapes
Good durability, long storage cycle, allowing long-term operation
High-temperature resistance, good creep resistance, corrosion resistance and earthquake resistance under permanent load
