Report on Fiber-Reinforced Polymer (FRP) Reinforcement for Concrete Structures


The purpose of this report is to present the current state of knowledge with regard to applications of fiber-reinforced polymer (FRP) materials in concrete. This report summarizes the fundamental behavior, the most current research, designcodes, and practical applications of concrete and masonry structures containing FRP.

This document is intended to complement other reports (for example, standards anddesign guidelines) produced by ACI Committee 440, either by summarizing the research that supports those documents or by providing information on future developments of those documents. If an ACI guide is available, the guide document supersedes information in this report, and the guide should always be followed for design and application purposes. ACI Committee 440 is also in the process of developing new guides; thus, the current availability of guides should bechecked by the reader.

FRP materials are composite materials that typically consist of strong fibers embedded in a resin matrix. The fibers provide strength and stiffness to the composite and generally carry most of the applied loads. The matrix acts to bond and protect the fibers and to provide for transfer of stress from fiber to fiber through shear stresses. The most common fibers are glass, carbon, and aramid. Matrixes aretypically epoxies, polyesters, vinylesters, or phenolics
