Theoretical Analysis of Fiber Volume Fraction in Synthetical Sleepers

    Graphical Abstract
    • Abstract
  • For synthetical sleepers made of continuous fiber reinforced polyurethane foam composite,fiber volume fraction is an important parameter that determines properties of the sleepers.In this paper,theoretical limit and practical value of fiber volume fraction are analyzed,which is helpful for the design of synthetical sleepers.
