Recent advancements in the applications of fiber‐reinforced polymer structures in railway industry—A review

Abstract

AbstractThe application of fiber‐reinforced polymer (FRP) composite materials and structures in various industrial sectors is expanding significantly to meet the rising demand for efficient, reliable, and functional building materials. Using FRPs can be an excellent strategy for enhancing railway structures and equipment because of their high strength‐to‐weight ratio, tailorable mechanical properties, and suitable long‐term characteristics. However, the railway industry appears to be hesitant to adopt composite materials compared to other transportation sectors like aerospace. It seems that there is still a long way to go before FRPs reach their full potential in railway applications. The goal of the current study is to explore the current uses of FRPs in the railway industry and the significant challenges, obstacles and difficulties that must be overcome to put FRP‐based concepts into practice for structural and rail vehicle applications.Highlights Applications of FRPs in railway vehicles and rail lines are reviewed. Main challenges for utilization of FRP in railway industry are studied. Future trends and applications of FRPs in the railway sector are introduced.
