Carbon Fiber Reinforced Polymer (CFRP) Fabric Strengthening

Jul 02, 2025

Carbon fiber fabric strengthening is an efficient, lightweight, and convenient structural reinforcement method. This technique utilizes carbon fiber fabric combined with a matching impregnating resin to form a high-performance carbon fiber composite sheet reinforcement system.

Carbon fiber fabric offers significant advantages in strengthening projects due to its light weight, high strength, high modulus, corrosion resistance, high-temperature resistance, wear resistance, and excellent constructability:

Lightweight, No Added Burden: Carbon fiber fabric is extremely lightweight (common specifications are 200g/m² and 300g/m², corresponding to thicknesses of approximately 0.111mm and 0.167mm respectively). It adds virtually no weight to the component, does not alter cross-sectional dimensions, and is convenient to install.

High Strength, High Efficiency: Possesses extremely high tensile strength (Grade I ≥3400MPa, Grade II ≥3000MPa) and high elastic modulus (Grade I ≥2.3x10^5 MPa, Grade II ≥2.0x10^5 MPa). The reinforcement effect can achieve levels comparable to steel plate strengthening.

Durable and Corrosion Resistant: Suitable for harsh environments such as high acid, alkali, salt, and atmospheric corrosion, with excellent durability.

Furthermore, carbon fiber fabric has excellent flexibility. It can be cut to required shapes and tightly bonded to the surfaces of various reinforced concrete components like beams, columns, slabs, pipes, and walls. Construction quality is easy to ensure.
