Tensile properties of braided FRP rods for concrete reinforcement
AbstractFiber-reinforced-plastics (FRP) elements are being considered worldwide as an alternative type of reinforcement for prestressed and non-prestressed concrete structures. This paper reports on the static tensile properties of braided epoxy-impregnated FRP rods made with glass, aramid and polyvinyl alcohol fibers. As one of the FRP manufacturing methods — brading — has several advantages, one of which is the deformed external rod-surface for improved bond with concrete. The research program was aimed to determine stress-strain curve shape, elastic modulus, Poisson's ratio, ultimate strength and ultimate elongation for three rod diameters. The apparent Poisson's ratio was measured with two independent methods (strain gages and rod volume change by water displacement). It was found that, for practical purposes, braided FRP rods can be considered linear elastic. Ultimate strength and rigidity are approximately 80% of that derived on the basis of the constituent material properties (when fivers ultimate elongation is smaller than that of the resin). Poisson's ratio and ultimate strength can be affected by rod size.
