Mechanics of FRP Composites- CFRP
High cost and difficulty of deployment are the main constraints in the use of Steel / Concrete Jacketing for Structural Rehabilitation. CFRP Laminates reduce both cost and complexity; they indeed represent an innovative solution that overcomes the challenges in the traditional methods for Structural Rehabilitation.
FRP Composite systems- CFRP, are comprised of fiber reinforcements (high strength carbon, glass, aramid fibers or combination of them) impregnated with polymer matrix system. They can either be cast in-situ or pre-cured in the form of rigid laminates and/or specially designed profiles. They operate as external reinforcement, bonded to the structural members through specially formulated epoxy resin systems, to resist tensile forces in the principal fiber direction. With the use of FRP Composite Materials- CFRP in construction, it is possible to increase flexural and shear strength of existing structural members, and also increase in load carrying capacity [increase of concrete's strength and strain] of compression members by way of confinement.
