A State-of-the-Art Review of Research and Application of FRP Composites in Railway Infrastructure
With the advancement of material science and industrial technology,composite materials have gained rapid development and been widely used in multiple fields.Currently,the railway has been booming in China,with the increase in railway mileage each year,the railway network has been becoming denser.Technical difficulties may arise in both the construction and service stages of railway,and the use of com-posite materials provides a new solution.Based on rational optimization of materials and structures,com-posite materials have solved some difficulties and gradually been used in railway infrastructure.However,due to the special requirements of railway infrastructure,the application of composite materials has still been restricted and their potential has not been fully unleashed.To promote the further development of com-posite materials in railway infrastructure,the state-of-the-art of the research and application of composite materials in railway infrastructure were reviewed,their development prospects and the problems hindering their development were analyzed.Finally,the development directions for future were proposed.
