You think it's a regular board? Noooo! In fact, it is a new type of structural reinforcement material - carbon fiber plate
With the continuous development of the building reinforcement industry, carbon fiber plates are highly favored by reinforcers due to their excellent performance and broad application prospects!
As a new type of structural reinforcement material, a series of issues need to be noted during the construction of carbon fiber plates to ensure construction quality and structural safety. Today, we will take you to have a detailed understanding of the relevant knowledge of carbon fiber plates in terms of material application, product features, and construction techniques.

I. Main Applications
(1) Reinforcement for controlling cracks in reinforced concrete bridges;
(2) Bending resistance reinforcement of slab beams, box beams, and T beams of reinforced concrete bridges;
(3) Bending resistance reinforcement and crack control reinforcement of large-span structural beams and slabs in civil buildings, industrial factories, etc.;
(4) Reinforcement of large-span reinforced concrete bridges to enhance bearing capacity, widely used in prestressed or non-prestressed bridge structures.
II. Product Features
(1) Light weight, easy operation and no need for large mechanical equipment;
(2) High tensile strength, several times that of ordinary steel, and better elastic modulus than steel, with excellent creep resistance, corrosion resistance and seismic resistance;
(3) High strength, with a mass of only 1/5 of steel, high toughness, can be coiled, and can be supplied in large lengths without overlapping;
(4) Little change to the shape of components and no impact on the net space of the structure;
(5) Convenient construction of carbon fiber plates, no complex operations, and construction quality is easily guaranteed.
III. Model Specifications
The thickness of SHIBANG carbon fiber plates is 1.2mm, 1.4mm, 2.0mm and 3.0mm. For detailed model specifications, please refer to the above picture.
IV. Construction Techniques
(1) Construction Preparation: Position and set out according to the design drawings;
(2) Substrate Treatment: Chisel off the plaster layer on the concrete surface of the component to be reinforced and polish the surface flat;
(3) And blow off the dust on the concrete surface;
(4) Prepare Glue: According to the weight ratio A:B = 3:1, evenly stir components A and B in the packaging barrel;
(5) Apply Glue: Evenly apply the prepared glue on the surface of the carbon plate to avoid generating bubbles;
(6) Paste the Carbon Plate: Paste the carbon plate on the concrete surface, remove the excess glue around and fix it;
(7) Curing and Maintenance: At room temperature, the maintenance time should not be less than 24 hours.
V. Comparison with Carbon Fiber Cloth
Let me emphasize one point. Many people may have questions after seeing the introduction of the above carbon fiber plates? The features and advantages that carbon fiber plates possess, carbon fiber cloth also has. Why not choose carbon fiber cloth?
This is because it is concluded through relevant mechanical property tests and calculations: One carbon fiber plate can be equivalent to 4-8 carbon fiber cloths. When the number of layers of carbon fiber cloth pasted exceeds three layers, it is necessary to replace it with carbon fiber plate reinforcement.
Carbon Fiber Plate
The construction of carbon fiber plates is a complex and important project. Not only should attention be paid to the selection of materials and the control of product quality, but also strict requirements should be imposed on the standardized operation of construction. Only in this way can carbon fiber plates truly perform better and be more widely applied in future engineering practices!
SHB-A502 carbon fiber plate is a unidirectional plate for carbon fiber reinforcement and strengthening. Its molding process is to impregnate carbon fibers with resin, cure them in a mold and continuously pultrude them. The unidirectional carbon fiber plate can give full play to the strength and modulus of elasticity of carbon fibers. During construction, the resin curing stage of unidirectional carbon fiber fabric can be omitted, the strength utilization efficiency is high, and the construction is convenient.
