Crack Repair Carbon Fiber Reinforced Polymer Prepressed Carbon
Fiber Strip With High Strength
Carbon Fiber Reinforced Polymer (CFRP) Post-tensioning Systems
Prepressed Carbon Fiber Strip is high strength and modulus
materials which can strengthen the building and bridge for seams,
columns,
Post-tensioned systems are effective for control of structural
cracks and deflections and to increase fatigue resistance and
seismic resistance. provides a unique system based on
post-tensioned CFRP plates.
CARBON FIBER STRIP
Thickness:1.2mm, 1.4mm, 2.0mm, 3.0mm
Density: 1.6g/cm³
Packing: 100 meters/roll
Width: 50mm, 100mm or to be customized.
Carbon fiber reinforced polymer(CFRP) strip/plate/laminate is pre-cured composite laminates, bonding onto the structure as
externally reinforcement using XQ-JGN31P epoxy resin as the
adhesive.
Carbon fiber laminate/strip/plate strengthening systems for
strengthening, repair and rehabilitation of masonry, concrete,
steel and wooden structures.

Application:
• Before applying the structural adhesive to the laminate, the
sanded side of the laminate is wiped with acetone or other solvent
until any excess residue (e.g., carbon dust) is removed. Observe
proper fire and health precautions when using solvents.
• Apply thin prime coat of CFRP sheet to the substrate surface
using a ¼” nap roller or brush. Application should be 1/2” wider
than the plate to be used.
• Apply 1/16” (1.5 mm) thick coat of the thickened CFRP sheet to
the cleaned, sanded side of the laminate surface. Plate laminates
should be applied with approved epoxy adhesive.
• Press the laminates against the working surface using a hard
rubber roller to achieve a void free bond line with thickness
between 1/16” to 3/32” (1.5 to 2.5 mm). Excess adhesive is then
removed from the sides of the laminate before it cures.
• The laminate may be coated with a protective or decorative
coating.
• Test plates may be simultaneously installed adjacent to the area
being strengthened and should be prepared using the same method
described above. Bond pull-off tests are performed to validate
proper installation. The bond strength of the plate to concrete may
be verified by random pull-off testing at the discretion of the
engineer. Minimum tensile strength of 200 psi must be achieved.
