Synthesis and Characterization of the Mechanical Properties of a New Polymer and Fiber-Reinforced Cementitious Slab Material for Bridges

Abstract:

This paper presents the experimental determination of the mechanical and structural properties of a bridge slab constructed with Fiber Reinforced Polymers (FRP), specifically vinyl ester resin reinforced with E-glass fibers (E-glass). The fibers were used in the form of a two-dimensional stitched fabric (NCF) and, for the first time, a three-dimensional braid. The slab is constructed by bonding beams with a triangular cross-section and two flat plates that form the top and bottom surfaces of the panel. The material was first characterized at the level of coupon-sized specimens, where its physical and mechanical properties were determined. The structural properties of the beams were determined by bending tests where a three-potentiometer arrangement was used to simultaneously measure vertical and lateral deflections and rotation, including the use of a gravity load simulator. Finally, the flexural properties of the panel …
