The CTech-LLC® Carbon Wrap is high strength carbon fabric designed for structural reinforcement applications as part of the CTech-LLC® FRP strengthening system. A wide range of uni-directional and bi-directional carbon fabrics in different weights are available for installation using the dry or wet application process to meet the specific requirements of each project.
UCW™: High strength unidirectional carbon wrap with fibers oriented in the 0° direction weighing 160, 200, 230, 300 and 400 g per m².
BCW™: High strength bidirectional carbon wrap with fibers oriented in the 0° and 90° directions weighing 160, 200, 320 g per m².

Key Features

  • Lightweight, flexible, high-strength fiber can be used in different surfaces like circular columns and other arched surfaces.
  • Chemical and corrosion resistant.
  • Compatible with different materials and standard adhesive resins.
  • Easy to impregnate using wet or dry lay-up methods.
  • Low aesthetic impact.


  • Strengthen for increasing load capacity.
  • Address changes in structural system, like slab openings and walls, beams or columns removal.
  • Retrofit for seismic, wind or blast.
  • Restore strength of structural elements damaged by fire or vehicle impact.
  • Restore strength to deteriorated and corroded members.
  • Strengthen for design or construction defects.

Storage Conditions

Carbon fibers should be stored at +10°C to +40°C and should not be exposed to direct sunlight. Keep the carbon fabrics in a dry place.

Shelf Life

10 years in unopened, undamaged carton
