Fabric strengthening systems, also called fiber reinforced polymer (FRP) systems, consist of woven or stitched, unidirectional, carbon and glass fiber fabrics and impregnating resins. This unique combination makes this a multifunctional material for many applications including confinement, shear, and seismic upgrading and strengthening of weak concrete, masonry, natural stone and timber structures.
