Carbon fiber boasts many advantageous features:

It has a specific gravity just 1/4 that of iron, yet approximately 10 times the strength of steel, and it is highly chemically stable, making it resistant to salt damage.

Replark™ is a repair and reinforcement material made of unidirectional carbon fiber for steel and concrete structures. As a fabric, Replark™ can be applied to structures of various shapes and offers excellent workability.

The grade of Replark™ made with PAN-based carbon fibers can be used to enhance the load bearing capacity of such structures as bridge columns, while the high-elastic-modulus grade made with pitch-based carbon fibers can greatly reduce rebar stress.
