FRP Rebar is a non-corrosive alternative for steel rebar in concrete reinforcement. It comprises two elements, a fibre and a matrix resin. The fibre used is usually carbon, aramid, basalt, or glass whereas the matrix resin is composed of either polyester, epoxy, or vinyl ester. FRP rebar is a spiral wrapped fiberglass rod which is light in weight and easy to handle as well. Also, it is electrically and thermally non-conductive, efficiently resists heat transfer and possesses greater tensile strength than steel.

FRP Rebars – Characteristic Properties

  • Linear – Elastic Behavior up to failure under tensile load
  • Ultimate tensile strength, which is twice the yield strength of steel
  • 1/4th the weight of steel rebar
  • Electromagnetically neutral and thermally non conductive
  • Non-corrosive (provides longer life and can be used without any coating in adverse/harsh environment)

FRP Rebars – Why and Where should be used

  • Concrete structures susceptible to corrosion
  • Concrete structures which require non ferrous rebars due to thermal non conductivity or electromagnetic consideration
  • Where machinery will consume the rebar (Cutting is required, Tunnel – Soft Eye)
  • Low Demand Slab Applications (Lower labour cost due to light weight of FRP)
