Fiber Reinforced (FR) composites have become increasingly popular as retrofit solutions for buildings and infrastructure due to their ease of application, lightweight properties, and corrosion resistance. However, there are still research needs in this area that hinder wider adoption of fiber reinforced polymers (FRP) retrofit solutions and limit the understanding of initial and long-term performance of FRP-retrofitted components and structures. This paper presents the findings of an extensive literature review conducted by the authors to identify the state-of-the-art of FR composites, FRP-retrofitted structures and infrastructure, and guidelines and standards that address the testing, evaluation, and design of these systems. Research needs for FRP composites identified during a National Institute of Standards and Technology (NIST) workshop that convened a group of experts in industry, academia, and manufacturing are discussed. An overview of those research needs that received the highest ranking in this workshop are presented in this paper. Implementation of these ranked research needs by the FR composite research community, including NIST, will serve to impact and advance the field of FRP retrofit of buildings and infrastructure.
