Carbon Fiber Reinforcements

Unidirectional carbon fiber fabric for strengthening concrete, steel, wood and masonry structures

Carbon fiber wrap is a lightweight, high-strength unidirectional reinforcement material designed to enhance the structural performance of concrete, steel, wood, and masonry components. It offers exceptional tensile strength, along with excellent resistance to acidic and alkaline environments, making it suitable for demanding structural retrofitting and reinforcement projects.

This carbon fiber reinforcement material is easy to handle and install, and it effectively improves load-bearing capacity, seismic resilience, and long-term durability of structural elements without adding significant weight or altering the original dimensions.

Features

Lightweight: Adds no significant dead load and does not alter the cross-sectional dimensions of structural components, making it ideal for retrofit work
Flexible and formable: Can be bent and wrapped around curved or irregular surfaces, suitable for strengthening non-linear or uniquely shaped elements
Extremely high tensile strength: Up to 8 times stronger than steel, with minimal thickness, allowing for overlapping applications without bulk
Smooth and uniform surface: Clean-cut edges with excellent surface contact, ensuring close bonding to concrete for consistent installation quality
Resistant to chemical corrosion: Strong acid and alkali resistance, non-toxic, and free of irritating odors
Long-term durability: Made from carbon-based material with high chemical stability, rated for 50 years of performance under humid and thermal aging conditions
