Fibre-reinforced polymer (FRP) composites

Abstract

The first part of this chapter focuses on the constituent materials (fibres and polymeric matrices), manufacturing processes, general properties and field of application of fibre reinforced polymer (FRP) composites used in civil engineering applications. Subsequently, detailed information is provided about the following three main types of FRP shapes used in structural applications: (1) glass fibre-reinforced polymer (GFRP) pultruded profiles; (2) FRP rebars and (3) FRP strengthening systems. For each of these three main FRP typologies, the following aspects are discussed: Geometries, typical physical and mechanical properties, advantages and difficulties compared to more traditional construction materials, field of application, application process and connection technology, and regulation.
