Abstract

A flexible fiber reinforced composite rebar structure includes a plurality of continuous fibers embedded within a thermoplastic resin. The rebar structure has an elliptical cross sectional shape with an aspect ratio of about two to one and a twist with a twist pitch of about 30 cm. The thermoplastic resin matrix enables the rebar structure to be bent in the field by the application of heat to soften the structure and thereafter cooled to return to a rigid state.
