Unidirectional and Bidirectional Carbon Fiber Wrap

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.

Applications

• 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
