The characteristics of railway sleeper
2021-09-09
Railway Composite Sleeper is composed of continuous glass fiber reinforced polyurethane foam material.It has the characteristics of FRP composite material and foam material,and has the advantages of natural wood and plastic.The structure has excellent mechanical properties.To meet the requirements of the role of sleeper in ballasttrack structure and overcome the shortcomings of existing sleeper. Composite Sleeper has high specific strength,large specific modulus and can be used as structural material.And light weight,heat preservation,chemical corrosion resistance,insulation,aging resistance and other characteristics.With similar properties of wood,such as nail,riveting and so on.At present,it is mainly used in special parts of high-speed railway and subway(such as turnout,bridge,platform,etc.),especially in places where the use of concrete sleepers is restricted.
