200gsm High Modulus Carbon Fiber Fabric For Building Wall Strengthening
for columns, beams, slabs,
CFRP Carbon Fiber fabric
carbon fiber wrap
Carbon Fabric strengthening systems, also called Carbon fiber reinforced polymer (CFRP) systems, consist of woven or stitched, unidirectional, carbon fiber fabrics and impregnating resins. This unique combination makes this a multifunctional material for many applications including confinement, shear, and seismic upgrading and strengthening of weak concrete, masonry, natural stone and timber structures.
- Tested for durability under many demanding conditions to ensure long-term performance in different applications and environments.
- Proven outstanding performance for strengthening irregularly-shaped structures and substrates.
- Installation is extremely flexible and easy, ensuring minimal down time.
- Our products come with over 15 years of experience with projects in all regions.

Processing Flow:
unloading→ Base layer treatment → glue resin on base layer → leveling → paste Carbon fiber sheet ( please pay attention for safety as the carbon fabric is conductive → Inspection → Surface protecting and decoration.
Attention
1, carbon fabric cloth is conductive, please leave far away from electrical equipment and power supply, or take reliable protection
2, carbon cloth bent should be avoided in the process
3, the surface should be clean and dry;
4, temperature theoretically should be 5-40 ℃
5, Processing in rain and outdoor is prohibited
6, If relative humidity is greater than 85% or condensation on the concrete surface, Processing is not allowed;
7, Matched resin shall be stored sealed and away from fire and direct sunlight.
8, The place of the formulation and use of resins should maintain good ventilation;
9, on-site workers should take appropriate protection measures.
Comparison
1. Material quality
many suppliers use basalt fiber, aramid fiber contracted black to posing as carbon fiber cloth, this will caused project quality unqualified, so firstly need to know that the carbon fiber has black and bright tows, it will not curl but red as steel wire after burning, smooth, glossy, well-distributed,and with good conductive performance
2, Bonding quality
strictly abide with <<processing and inspection standard for carbon fiber>> Ensuring the quality of bonding quality;
3, carbon fiber has good tensile strength, but is poor for fold and bending
4, carbon fiber cloth shall be covered with anti-corrosion mortars after processing, long time exposure will reduce its service life.
