The wooden pillow,concrete pillow and steel pillow of traditional sleeper have shortcomings in working performance and sustainable development.Wooden pillow has short life,easy wear out,easy to suffer biological erosion,use preservative harm environment and human body health to wait for inadequacy.The shortcomings of concrete pillow are mainly stiffness,brittleness,weight and recycling difficulties.And Railway Composite Sleeper is composed of continuous glass fiber reinforced polyurethane foam material,it has the characteristics of glass fiber reinforced plastic composite materials and foam,with the advantage of natural wood,plastic,such as its higher than strong,larger than the modulus,can be used as structure materials,and qualitative light,thermal insulation,chemical corrosion,insulation resistance,ageing resistance characteristic such as being strong of performance,but also has similar performance of lumber,If it can be nailed,riveted and so on. 
Composite Sleeper has high strength and good performance in keeping track.Acid resistance,alkali resistance,salt fog resistance,uv resistance,good moisture and heat aging performance;Insulation,flame retardant,pest control.Low life cycle comprehensive cost.Mainly used in high-speed railway and subway special use parts(such as turnout,bridge,platform,etc.),especially in the use of restricted concrete sleepers.
