CFRP Strengthening Fabric
Unidirectional carbon fibre reinforcement fabric for externally bonded structural strengthening of beams, columns, and slabs.
Overview
High-strength carbon. Engineered for retrofit.
CFRP Strengthening Fabric is the unidirectional carbon-fibre reinforcement specified for externally bonded reinforcement (EBR) of concrete, masonry, and timber structures. Tensile strength exceeds 3300 MPa — roughly ten times that of structural steel at a fraction of the dead-load impact.
Installed via wet lay-up with structural saturating epoxy. Supplied in 200–600 g/m² areal weights and 300 / 500 mm roll widths to match engineer-of-record specifications under EN 1504-4 and ACI 440.2R.
Key Features
- Tensile strength ≥ 3300 MPa
- Modulus of elasticity ≥ 230 GPa
- Light weight — minimal added dead load
- Corrosion-immune — does not rust like steel
- Thin profile — does not reduce headroom
- Wet lay-up with structural saturating epoxy
