Carbon fiber strengthening slab, that is, using carbon fiber reinforced polymer (CFRP) to strengthen the slab, has the following advantages:

Lightweight and High Strength
Excellent mechanical properties: Carbon fiber has a high strength-to-weight ratio, with its tensile strength far exceeding that of ordinary steel (up to 3,400 MPa or more), while the density is only about 1/4 of steel.

Little additional load on the structure: When used for slab strengthening, it hardly increases the self-weight and section size of the slab, and is especially suitable for projects with strict requirements on load increase, such as historical buildings or structures with limited bearing capacity.

Environmental Protection

Less construction waste: The construction process produces less waste, and carbon fiber materials are non-toxic and harmless, which is in line with the requirements of environmental protection.

Good Durability and Corrosion Resistance
Strong resistance to environmental factors: Carbon fiber is not easy to rust or corrode, and can maintain stable performance in harsh environments such as humidity, chemical corrosion, and high temperature, which is beneficial to the long-term service life of the structure.

Reduced maintenance costs: Compared with traditional steel reinforcement methods, it does not require regular anti-corrosion maintenance, saving maintenance costs in the later stage.

Convenient Construction and High Efficiency
Simple construction process: The construction of carbon fiber strengthening does not require large-scale mechanical equipment. It mainly relies on bonding agents to paste carbon fiber sheets on the surface of the slab, with short construction period and high efficiency.

Little impact on the original structure: There is no need for operations such as punching and grooving on the slab, which avoids damage to the original structure and reduces the risk of structural safety.

Suitable for various shapes: Carbon fiber sheets can be cut and pasted according to the shape and size of the slab, and are suitable for strengthening slabs with complex shapes or special structures.

Good Flexibility and Adaptability
Suitable for multiple strengthening purposes: It can be used to improve the bearing capacity, flexural resistance, shear resistance, and crack resistance of the slab, and can be flexibly designed according to different strengthening requirements.

Compatible with the original structure: After strengthening, the carbon fiber and the slab form a whole, which can effectively transfer stress and maintain the integrity of the structure.

Economic Benefits
Comprehensive cost saving: due to the advantages of short construction period, low maintenance cost, and little impact on the use of the building (such as no need to stop using the building for a long time during construction), the comprehensive cost is often lower than that of traditional strengthening methods.

Good Sealing and Aesthetic Performance

Smooth surface after construction: The thickness of the carbon fiber sheet is thin (usually about 0.111-0.167 mm). After pasting, the surface of the slab is relatively smooth, which has little impact on the use space and architectural aesthetics of the building.

Good sealing effect: The bonding agent can fill the tiny cracks on the surface of the slab, improving the sealing performance of the slab and preventing the intrusion of moisture and harmful substances.
