The form and mechanism of CFRP laminate bonded reinforcement are similar to those of steel bonded reinforcement, which is essentially equivalent to increasing the reinforcement of members, and can generally be replaced by each other in shear and bending reinforcement.

Next, we will introduce the unique advantages of carbon fiber laminate.

Advantages of Reinforcement Method

If the design value of tensile strength of carbon fibre laminate is approximated to 2000 MPa and that of steel (Q235) is approximated to 200 MPa, then 0.1 mm thick carbon fibre laminate is equivalent to 1 mm thick steel sheet.

It hardly increases the cross-section of components. Carbon fibers laminate are light and thin. It does not need large construction machinery. It is easy to transport, store and construct. With the same amount of work, the construction period of bonding carbon fibers is about 40% of that of bonding steel.

Compared with steel, carbon fibers laminate are inert materials, stainless, not easily corroded by harmful media, and have good durability in harsh environments.

Material superiority

The effective bonding rate of carbon fibre laminate can also reach 100%. It is difficult to achieve 100% effective bonding surface for bonding steel sheet. The corresponding acceptance standard is only 70%.
