Carbon Fiber Fabric for Structural Strengthening
carbon fiber fabric for structural strengthening

Product Overview

Carbon Fiber Fabric is a high-performance reinforcement material used in structural strengthening and repair.

It is widely applied to concrete beams, slabs, columns, bridges, tunnels, and other civil engineering structures.

When used together with compatible epoxy resin, the fabric forms a lightweight and high-strength CFRP reinforcement system that helps improve load-bearing capacity, flexural performance, shear resistance, and seismic behavior.

Compared with traditional steel reinforcement methods, carbon fiber fabric offers lower weight, easier installation, corrosion resistance, and minimal increase in structural dead load.

Advantages

Carbon fiber fabric provides excellent tensile performance while adding very little weight to the original structure.
It is especially suitable for projects where traditional steel plate reinforcement is difficult or where long-term corrosion resistance is required.

Its flexibility also allows it to be applied to different structural shapes, including beams, columns, curved surfaces, and confined spaces. This makes it an efficient reinforcement material for both new repair projects and long-term structural rehabilitation.
