Carbon fiber fabric

CFRP Carbon Fiber Sheet 600gsm for Tunnel and Pipe Structural strengthening

Item# CarbonWrap 305/ 306

Product Description:

this product can be used together with epoxy resin adhesive as carbon fiber composite materials to make an enhanced system of high performance carbon fiber fabric and sheet. Suitable for increasing the working load of building, changing the using function of project, materials ageing, concrete strength grade below design value, structure crack treatment, repairing of section unit under bad condition, reinforcement of protecting facility.

2. Main Performance

Remarks: all data are average values.

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.
