Carbon fiber reinforcement, I believe many people will know. As a new type of reinforcement method, carbon fiber reinforcement is now widely used in the building reinforcement industry and plays an important role. Carbon fiber reinforcement includes two types: carbon fiber cloth reinforcement and carbon fiber plate reinforcement. Carbon fiber cloth reinforcement is very common in reinforcement construction. Carbon fiber cloth has one -way carbon fiber cloth and two -way carbon fiber. Is the reinforcement of carbon fiber cloth one -way or two -way?

One -way carbon fiber cloth refers to a carbon fiber cloth in one direction (usually the direction) of the carbon fiber, so the entire strength of the cloth is in the same direction. The carbon fiber with high tensile strength is pre -immersed in epoxy resin into composite enhanced materials (unidirectional continuous fibers). Use epoxy resin bonding agents to paste the stretch direction or vertically in the cracking direction on the structure to be strengthened to form a new complex. The enhanced paste material and the original reinforced concrete jointly increase the ability to crack or shear the structure, and improve the strength, rigidity, crack resistance and extension of the structure.

One -way carbon fiber cloth is woven from carbon fiber beam in the same direction. The two -way carbon fiber cloth is woven in two directions of the latitude and weft. The carbon fiber cloth we usually refer to is one -way carbon fiber cloth, so the use of one -way carbon fiber cloth will be better. The two -way carbon fiber cloth is more suitable for the reinforcement of irregular structural cracks in the direction, or the reinforcement of the building and other buildings, and the cost is relatively high. The one -way carbon fiber cloth is more suitable for common reinforcement projects, and the cost is relatively low. Therefore, it can also be explained why one -way carbon cloth is used more. The performance of one -way carbon cloth can already meet ordinary reinforcement projects, and the perchability of carbon fibrous glue is better.

The advantages of one -way carbon fiber cloth reinforcement construction:

1. The construction quality is easy to ensure that the carbon fiber cloth is soft, even if it is reinforced on an object with uneven surface, it also guarantees 100%effective paste. If there are bubbles on the surface of the paste, you can easily use the syringe injection of the paste to drive away the air, and it is difficult to do it.

2. There is no wet operation for construction convenience, no large construction machinery is required, and there is no need to fixed facilities on the spot. Carbon fiber cloth can be arbitrarily tailored, with simple construction and short construction period.

3. After the thickness of the thickness, the weight of the weight is less than 1.0kg per square meter (including glue weight), the thickness of the carbon fiber cloth is only 0.111 mm /0.167mm/0.333mm. After repair, the self -weight and shape size will not be increased.

4. Applicable to the reinforcement of carbon fiber cloth reinforcement can be widely used in various types and shapes of concrete structures, and it does not change the structure shape and does not affect the appearance of the structure. Carbon fiber cloth has excellent physical mechanical properties. The tensile strength is 7-10 times higher than that of ordinary steel. The elastic modulus is closer to the steel, which is extremely suitable for reinforcement and repair of reinforced concrete.
