Product characteristics 

Carbon fiber cloth has high strength, small density and thin thickness, and hardly increases the self-weight and cross-section size of the reinforced members. It is widely applicable to the reinforcement and repair of various structural types and shapes of buildings, bridges and tunnels, as well as seismic reinforcement and structural reinforcement of joints. The construction is convenient, without large machinery and equipment, no wet operation, no fire, no on-site fixed facilities, less construction site occupied, and high construction efficiency. High durability, no rust, very suitable for use in high acid, alkali, salt and atmospheric corrosion environment.

Construction scope 

It is suitable for strengthening and repairing various structural types and parts, such as beams, slabs, columns, roof trusses, piers, bridges, cylinders, shells and other structures. It is suitable for strengthening concrete structure, masonry structure, timber structure and seismic strengthening in port engineering, water conservancy and Hydropower engineering, especially for complex forms such as curved surface and joints.

Key points of construction 

Key points of carbon fiber cloth reinforcement construction: unloading basement treatment- leveling- bottom coating -pasting- protection

Construction preparation

Draw up the construction plan, and prepare the carbon fiber sheets, matching resins, machines and tools before construction.

Surface treatment of concrete

Remove the deteriorated concrete such as peeling, loosening, honeycombing and corrosion on the surface of the strengthened component, expose the concrete structure layer, and repair the surface with repair materials. According to the design requirements, cracks are grouted or sealed.

Construction preparation and painting 

The bottom resin is prepared according to the technological regulations, and the bottom resin is evenly applied on the surface of concrete. On the surface of the resin, the next working procedure should be carried out immediately after touching the drying. The leveling material is prepared and used to repair the uneven part. The concave part of the concrete surface is filled with leveling material and the smooth arc is restored with leveling material at the corner.

 Construction & paste carbon cloth 

(1) cutting carbon cloth / aramid cloth according to the design requirements; (2) preparing impregnating resin and applying it evenly on the member to be pasted; (3) rolling along the fiber direction for many times, extruding air bubbles, and making the impregnated resin fully impregnate the carbon cloth / aramid cloth; The surface of carbon cloth / aramid cloth is evenly coated with impregnated resin.

Surface protection

Processing in accordance with relevant specifications and ensuring reliable bonding between protective materials and carbon cloth/aramid cloth.

Attention 

1. Carbon cloth is a conductive material. It should be far away from electrical equipment and power supply during construction, or take reliable protective measures.

2. Carbon cloth bending should be avoided during construction.

3. Carbon fibre cloth matching resin should be sealed and stored away from fire source to avoid direct sunlight.

4. The preparation and use of resins should be kept well ventilated.

5. On-site construction personnel should take corresponding labor protection measures.
