Dubai Vertical Unidirectional High quality CFRP carbon fiber for structural strengthening

Carbon Fiber Reinforced Polymers for Structural Strengthening. These fabrics are applied onto the surface of existing structural members in buildings, bridges and other structures. The result is an externally bonded CFRP (carbon fiber reinforced polymer) reinforcement system engineered to increase the structural performance

CFRP strengthening of existing structures can involve complex evaluation, design, and detailing processes, requiring a good understanding of the existing structural conditions along with the materials used to repair the structure prior to FRP installation. The suitability of FRP for a strengthening project can be determined by understanding what FRP is and the advantages it offers, but more importantly, its limitations.

The primary benefit of CFRP systems versus traditional retrofit and repair methods is that significant flexural, lateral, axial or shear strength gains can be achieved with an easy-to-apply composite that does not add significant weight or mass to the structure of building, highway, bridge, tunnel.

Carbon fiber is light weight, easy-to-install, strong (10x stronger than steel) and non-corrosive, which eliminates the need for maintenance. Carbon fiber can also be easily painted over or covered with a finishing product for aesthetic appeal.

Carbon fiber has 3 attributes that engineers, specifiers and contractors look at depending on the project on-hand:

• Weave Orientation (Unidirectional Horizontal, Unidirectional Vertical and Bidirectional)
• Weight (200 GSM, 300 GSM, 400 GSM, 560 GSM, 600 GSM)
• Width (10cm, 30cm, 50cm)

High strength to weight ratio

Excellent resistance to creep and fatigue

Extremely durable

Low aesthetic impact

Used for shear, confinement, seismic or flexural strengthening

Versatile, can be wrapped around complex geometries

High Strength

Preparation works

Surface must be clean and sound. It may be dry or damp, but free of standing water and frost. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials and other bond inhibiting materials from the surface. Existing uneven surfaces must be filled with an appropriate repair mortar. The adhesive strength of the concrete must be verified after surface preparation by random pull-off testing (ASTM D 4541) at the discretion of the engineer. Minimum tensile strength required is 200 psi (1.4 MPa) with concrete substrate failure (typical).
