Common Problems And Solutions For Carbon Fiber Cloth Reinforcement

Nov. 08, 2019

Carbon Fiber Cloth is used for tensile, shear and seismic strengthening of structural members. This material is used together with the matching impregnating rubber to form a carbon fiber composite material, which can form a complete and excellent carbon fiber cloth sheet reinforcement system, which is suitable for treating building load. Increase, engineering use function change, material aging, concrete strength grade is lower than design value, structural crack treatment, repair of damaged components in harsh environment, protection reinforcement. The strength is high, the density is small, and the thickness is thin, and the self-weight and cross-sectional size of the reinforcing member are not substantially increased. It has wide application range and is widely used in various types of structures such as building bridges and tunnels, reinforcement and repair of seismic structures and structural reinforcement of joints. Convenient construction, no need for large-scale machine equipment, no wet operation, no need for hot fire, no need for on-site fixed facilities, less use of state labor, and high construction efficiency. High durability, because it does not rust, it is very suitable for use in high acid, alkali, salt and atmospheric corrosive environments. So what problems will occur during the use of carbon fiber cloth? How to solve it? Carbon Fiber Sheet Supplier will come to tell you.


Common problems in carbon fiber cloth reinforcement engineering are listed:


1. The carbon fiber cloth and the carbon fiber glue used together with it are unqualified;

2. The surface treatment of the concrete structure during construction does not meet the requirements;

3. The method of using structural adhesive ratio, stirring, etc. does not meet the specifications for the use of structural adhesives, or the construction method of bonding carbon fiber cloth does not meet the requirements of construction specifications.


Due to the existence of these problems, the total effective bonding area of the concrete is less than 95% of the total bonding area, and small bubbles exist on the surface of the carbon fiber cloth. So how to solve the specific urinary calcium?

Solutions to common problems in carbon fiber cloth reinforcement engineering:


1. Material selection and procurement should select materials that meet the requirements according to the design and specification requirements of the design institute, and the procurement plan of the materials must be purchased after being reviewed by the technical person in charge; and the qualified materials should be selected before the construction. Sampling inspection is carried out to ensure that the quality and quality of the materials meet the design requirements.

2. Grinding treatment of the base surface of the concrete structure Firstly, the loose concrete is removed, and after repairing with the repair mortar, the construction is carried out. It should be noted that in the process of this process, the mortar should be dried before the next step can be carried out.

3. When the construction process does not meet the specifications, it is necessary for the professional to carry out the technical disclosure.


In addition, the matters needing attention in the reinforcement of carbon fiber cloth:


(1) The concrete to which the carbon fiber material is pasted shall be kept dry, and the moisture content of the surface layer shall not be greater than 4%.

(2) After the preparation of the carbon fiber cloth is finished, the carbon fiber cloth must be infiltrated with the supporting structural glue, so that the structural glue can penetrate into the gap between the carbon fiber monofilaments as much as possible to improve the work between the monofilaments. Performance.

(3) When the structural adhesive used in the pasting construction is completed, it should be used within the time specified in the manual. Otherwise, the reinforcement quality will be affected.

(4) Carbon fiber is a conductive fiber. Avoid contact with the power supply during construction to avoid electric shock.


The above is about the problems that may occur when the carbon fiber cloth is reinforced. I hope I can help you. In addition, if you have a need for carbon fiber cloth, Chemical Anchor and other building reinforcement materials, you can contact us, we can provide you with professional services.
