FRP (Fibre Reinforced Plastic) prestressing tendons consist of high strength/high stiffness carbon, glass or aramid fibres combined with a suitable resin, generally epoxy-based. Typical properties are given in the Table. FRP tendons require special anchors, generally resin-filled; normal steel barrel and wedge anchors cause local damage and premature anchorage failure.
FRP prestressing tendons have been used in a number of bridge decks North America, Japan and Europe; the first applications were in the mid-1980s. In addition, carbon FRP tendons have been used for the stays of cable-stayed bridges.
In addition there have been a number of conferences dealing with FRP prestressing and reinforcement materials.
