Unidirectional Grade 1 300gsm CFRP carbon fiber for structural strengthening
CFRP composites can be manufactured on site using the wet lay-up process in which a dry fabric, made of carbon or glass, is impregnated with epoxy and bonded to prepared concrete substrate. Once cured, the FRP becomes an integral part of the structural element, acting as an externally bonded reinforcing system. FRP composites can also be prefabricated in a manufacturing facility in which the material is pultruded to create different shapes that can be used for strengthening applications, such as rods, bars and plates.
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)

Advantages of CFRP Fabric
• Easy installation
• Corrosion resistance
• Short construction period
• No maintenance required
• Light weight, no influence to original structure
• Low cost, cost effective compared with other methods
l Adds strength without adding dead load
l Withstands sustained and cyclic load conditions
l Extremely resistant to wide range of environmental conditions
l Easy to conceal
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).
