A: Carbon fiber fabric is widely used for strengthening concrete beams, slabs, columns, bridges, tunnels, industrial buildings, and cracked floor structures. It is lightweight, high-strength, corrosion-resistant, and easy to install. When used with Grade-A carbon fiber impregnating adhesive, it can effectively improve structural bearing capacity and long-term durability.

A: Carbon fiber plate offers high stiffness and high tensile strength, making it suitable for bridge, floor slab, and beam reinforcement. Carbon fiber fabric is more flexible and is better suited for beam-column joints, irregular structures, curved surfaces, and large-area bonding reinforcement. The proper material should be selected according to the structural load, construction conditions, and engineering requirements.

A: Before construction, the concrete substrate should be cleaned and kept solid, flat, dry, and free of oil or dust. During installation, primer, leveling adhesive, and impregnating adhesive should be applied according to the specifications to ensure that the carbon fiber material is fully saturated and firmly bonded to the substrate. Proper curing should be carried out after construction to avoid early moisture, contamination, or loading.
