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)

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).
