Carbon Fiber (CFRP) Fabric
High-strength unidirectional carbon fiber fabric for externally bonded structural strengthening of beams, columns, and slabs.
Overview
Ten times the strength. A fraction of the weight.
Carbon Fiber (CFRP) Fabric is a unidirectional carbon fiber fabric for externally bonded reinforcement of concrete, masonry, and timber structures. With tensile strength exceeding 3300 MPa – roughly ten times that of structural steel – installed via wet lay-up with saturating epoxy.
The defining material of modern structural strengthening. Specified on seismic retrofits, change-of-use upgrades, and damage repair projects.
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
