    ​MasterBrace FIB 300-50CFS

    Unidirectional high-strength carbon fiber fabric for the MasterBrace Composite Strengthening System

    How does MasterBrace FIB 300-50CFS work?

    MasterBrace FIB 300-50 CFS is a dry fabric constructed of very high strength, aerospace grade carbon fibers. These fabrics are applied onto the surface of existing structural members in buildings, bridges, and other structures using the MasterBrace family of performance polymers.​

    The result is an externally bonded FRP (fiber reinforced polymer) reinforcement system that is engineered to increase the strength and structural performance of these members. Once installed, the MasterBrace System delivers externally bonded concrete reinforcement with outstanding long-term physical and mechanical properties.


    • Increase load-bearing capacity of concrete beams, slabs, walls and columns
    • Improve the seismic ductility of concrete columns
    • Improve the seismic response of concrete beam-column connections, shear walls and collector elements
    • Improve the seismic performance of masonry shear walls and in-fill walls
    • Restore structural capacity to damaged or deteriorated concrete structures
    • Increase the strength of concrete pipes, silos, tanks, chimneys and tunnels
    • Substitute reinforcing steel mistakenly omitted in the construction of concrete and masonry structures
    • Improve the blast resistance of concrete and masonry structures
    • Strengthening of some steel and timber structures
    • Vertical / Horizontal
    • Exterior / Interior
