Philippines Standard High Strength Carbon fiber CFRP fabric for
structural strengthening
Carbon fiber reinforced polymer fabric (CFRP fabric composite
strengthening system) for structural strengthening, repairing and
retrofitting of masonry, concrete, steel and wooden substrates.
CFRP composite strengthening of
columns,beams,slabs,walls,piles,pier caps in
building,bridge,highway,railway,tunnels,piers and civil airport.
The primary benefit of CFRP fabric 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.
CFRP fabric 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 CFRP
installation. The suitability of CFRP fabric for a strengthening
project can be determined by understanding what CFRP fabric is and
the advantages it offers, but more importantly, its limitations.

How to Use CFRP Fabric
• Surface treatment
• Applying primer
• Leveling
• Applying carbon fiber adhesive
• Externally bonded carbon fiber reinforced polymer(CFRP) fabric
• Applying carbon fiber adhesive again
• Curing and protecting
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).
