Carbon fiber wrapping system for structural reinforcement

The carbon fiber wrapping system is an effective solution for structural reinforcement. Carbon fiber has very high tensile strength and is very light. When bonded to the exterior of concrete columns, beams or slabs, it can significantly increase the strength without increasing the weight that would increase the load of the foundation and other structural members. Wrapping systems, usually made of a mixture of carbon fiber or glass fiber fabric and epoxy resin, are custom-designed for each project and application.

The carbon fiber wrapping system provides significant strength to the structure and prevents further corrosion and erosion. The impermeable material will protect the structure from moisture intrusion and further corrosion, thereby reducing the need for ongoing maintenance work. Carbon fiber has extremely high elasticity and light weight. When it is close to the outside of a solid part, pillar, or component, it can include critical mass, but not the weight that would amplify the individual load of the mechanism and other structures. Usually a mixture of carbon fiber or glass fiber texture and epoxy resin, the packaging frame is specially made for each enterprise and application.

Advantages of carbon fiber wrapping system

The use of carbon fiber-wrapped column reinforcement in new concrete can eliminate potential corrosion problems and significantly increase the structural strength of the components. Compared with traditional methods, the reinforcement technology of carbon wrapping used for pillars has the least interference with structural members. The columns are coated with carbon and are corrosion resistant; therefore, they are used for corrosion control and repair of reinforced concrete structures.

Application of carbon fiber wrapping system

The carbon fiber wrapping system is most suitable for projects subject to continuous collapse and corrosion, including:

• Columns strengthening
• Beams strengthening
• Slabs strengthening
• Walls strengthening
• Pipes strengthening
• Pier caps strengthening

Different types of carbon fiber wrapping system products are used for structural reinforcement

Unidirectional carbon fiber

Unidirectional carbon fiber fabric is a non-woven carbon fiber reinforced material, all fibers run in a parallel direction. With this fabric, there are no gaps between the fibers, and the fibers lie flat. No cross-sectional weave divides the fiber strength into half in the other direction. This allows the concentrated density of fibers to provide maximum longitudinal stretch potential-greater than any other fabric weave.

Carbon fiber plate

Carbon fiber reinforced polymer(CFRP) strip/plate/laminate is pre-cured composite laminates, bonding onto the structure as externally strengthening reinforcement using HM-120CP epoxy resin as the adhesive.
