What is the carbon fiber cloth U-shaped hoop?

Nov. 02, 2017

For those people who first go into the reinforcement industry, they can’t understand any technical terms completely. This will cause a lot of problems in the practical applications. They just copy the past experience and don’t analyze according to the actual situation. For example, the carbon fiber U-shaped hoop paste. Many people write to us and ask some questions. Such as, "Can carbon fiber cloth U-shaped hoop be replaced with the carbon fiber board?", or "How many layers should the carbon fiber cloth U-shaped hoop be pasted?" So today we will talk about how to operate the carbon fiber cloth U-shaped hoop.

1. How does the carbon fiber cloth U-shaped hoop know its engineering calculations?

When we do the bending reinforcement to the positive bending moment area of the beam and board, the carbon fiber cloth should extend to the edge of the bearing. On both sides of the key area of the concentrated load, the transverse pressure bar or the carbon fiber U-shaped hoop shall be set. The U-shaped hoop shall be pasted strictly according to the technical engineering calculation rules. The width of U-shaped hoop, the end of hoop should not be less than 2/3 of the width of the reinforcement fiber composite. And it should not be less than 200mm. The middle hoop should not be a half less than the width of the reinforcement fiber composite. And it should not be less than 100mm.

 

2. Can the carbon fiber cloth U-shaped hoop be replaced with the carbon fiber board?

Absolutely not! Carbon fiber board can not be bent, while carbon fiber cloth can be cut freely. And it can deform arbitrarily according to the structure. It can be pasted three layers according to the specification.

 

3. What should we do when the carbon fiber sheet extends to the edge of the support but it still does not meet the rules?

In the extension of the length of the carbon fiber cloth, we should set the pressure bars which are perpendicular to the direction of the stress carbon fiber. The press bars should be evenly arranged within the range of the extended anchorage length. And it must be set at the end of the extension length. The width of each pressure bar should not be a half less than the width of the reinforced carbon fiber cloth. The thickness of the pressure bar should not be a half less than the thickness of the reinforced carbon fiber cloth.

 

Above are some questions that people often ask us about the reinforcement of the carbon fiber cloth U-shaped hoop. In the actual project, if there are some regulations, we must carry out in accordance with the rules. If not, we should analyze according to the actual situation. If necessary, we should ask some experienced masters for help. Such as, us Mankate! If you need some materials for your projects, please remember to buy Mankate carbon fiber cloth.
