Fiber Reinforced Polymer Composites (FRPs) demonstrate advantages over traditional building materials for civil engineering infrastructure, as long as their long-term durability is guaranteed. Use of FRPs in civil engineering differs from other areas, such as aerospace, particularly because civil engineering structures have a far longer service life. Durability of Fiber Reinforced Polymer Composites for Civil Engineering presents the fundamentals of FRP durability in civil engineering environments under well-defined boundary conditions. The title gives physiochemical properties and durability for FRPs used in civil engineering, the theory of long-term durability mechanisms and prediction models, and provides methods for the evaluation of FRPs when exposed to various conditions. More specifically, eight chapters cover an introduction to FRPs; the fundamentals of long-term durability; performance and adhesives; resin matrices; CFRPs; GFRPs; BFRPs; and evaluating and predicting durability for FRPs. This volume provides a solution to researchers and engineers designing high-performing and durable FRP structures for civil engineering.
