Conventional carbon fiber used for reinforcement is generally 200 grams, 300 grams, 600 grams.

Although the thickness of the carbon cloth is thicker, the strength per unit area is higher.

But is thicker the better?

Actually not necessarily.

Because the carbon fiber is very thick, it is difficult to wet.

You also know that the principle of carbon fiber is that carbon fiber with extremely high tensile strength is bonded to the structure to be reinforced in the direction of tension or perpendicular to the crack direction with epoxy resin adhesive to form a new composite. The reinforced paste material and the original reinforced concrete are jointly stressed to increase the crack resistance or shear resistance of the structure, and improve the strength, stiffness, crack resistance and elongation of the structure.

So, normal specs will do.

If the strength of one layer does not meet the requirements, you can also paste 2 layers carbon fiber for strengthening.
