In the building reinforcement industry, the carbon fiber reinforcement method is very applicable, and many construction units will give priority to the carbon fiber reinforcement method.

There are two types of carbon fiber reinforcement, one is carbon fiber cloth reinforcement, which many people will know, and the other is carbon fiber plate reinforcement. Although the carbon fiber cloth reinforcement and the carbon fiber plate are the same carbon fiber materials, the two are different in reinforcement.

Compared with carbon fiber cloth, carbon fiber plate has certain advantages, so what are the advantages of carbon fiber plate reinforcement?

Advantages of CFRP fabric strengthening

• Easy installation

• Corrosion resistance

• Short construction period

• No maintenance required

• Light weight, no influence to original structure

• Low cost, cost effective compared with other methods

Advantages of CFRP plate strengthening

• Short construction period

• No maintenance required

• Easy installation, low installation cost

• Light weight, no influence to original structure

• Corrosion resistance, long-term effect of 50 years

• Cost effective compared with other retrofitting method

• 1 layers of CFRP plate is equivalent to 4-8 layers of CFRP fabric

Today, Horse introduces you to the advantages of carbon plate reinforcement:

01 Carbon fiber plate has good stress effect

The calculated tensile force of 10cm carbon cloth is 1600*100*0.167 (300g carbon cloth thickness)=26720N.

The calculated tensile force of the 10cm carbon plate is 1150*100*1.2=138000N.

From the calculation results, we can see that pasting a layer of 1.2mm thick carbon plate with the same width is more than 5 times the tensile force that a layer of 300g carbon cloth can bear.

02 Good strength utilization

Carbon cloth strength utilization rate:

1600/3400=47.1%

Carbon plate strength utilization rate:

1150/2400=47.9%

It can be seen that the carbon plate has a higher strength utilization rate than the carbon cloth.

03 Better control of the quality of the pasted carbon plate

The carbon plate is a carbon fiber raw wire formed by infiltrating and hardening using a resin. The material itself is hard, the glue layer is well controlled when applying glue, and the pressure is well controlled when pasting, so there will be no problem with the pasting effect. In the process of pasting carbon fiber cloth, there will be a series of common problems such as edge curling and bulging. And the carbon cloth paste is more demanding than the carbon substrate paste base.
