FRP Reinforcement of Concrete

Composition of Material

• Fiber-Reinforced Polymer (FRP) composites are
  typically made of fibers such as, glass, aramid,
  and carbon in a polyester or vinyl ester resin
  matrix

Steel Concrete Reinforcement Replacement?

• FRP bars are being researched to replace steel
  reinforcement in concrete.
• The corrosive effects of steel reduce the life of
  concretes structures.
• FRP composites are corrosion resistant,
  lightweight, and have high strength.
• Easy construction and handling
• Applications include the construction of new FRP
  bridge deck systems, new concrete decks with
  reinforcing FRP rebar, and the strengthening and
  repair of existing structures.

Presently

• FRP composites are still under testing and
  research.
• Connections are difficult.
• The fiber-reinforcement cant be bent in the
  field without reducing the strength of the
  material.
• More designing efforts are required for this
  material.
