Overview on FRB Pre-Stressed Tendons and its Fatigue Behavior

Abstract

Although a variety of techniques can be used to manufacture FRP shapes, a technique called pultrusion is used almost exclusively for the manufacture of FRP reinforcing rods. In this technique, continuous strands of the fibres are drawn from creels (spools of fibres) through a resin tank, where they are saturated with resin, pulled through several wiper rings, and finally pulled through a heated die. This process simultaneously forms, and heat cures the FRP into a reinforcing rod. To ensure a strong bond with concrete, a surface treatment is applied consisting of a spiral, or a braided wrap, or a coating of sand embedded in the outer surface of the polymer matrix [1]. The pultrusion process is illustrated schematically at (Figure 1). *Corresponding author: Ahmed I Hassanin, Faculty of Engineering, Egyptian Russian University, Cairo, Egypt.
