Fiber Composite Springs

Lightweight composite leaf spring with progressive characteristic

Composite tension leaf spring


  • Glass fibre composite tension leaf spring
  • Progressive characteristic due to bending and superposed
  • Length compensation within the spring



Progressive spring characteristic by tension single-leaf spring
  • Weight reduction up to 70% compared to a conventional
    multiple-steel-leaf spring (Example 5.9 kg to 22.8 kg)
  • Cost and system optimization through elimination of
    assembly parts
  • Reduction of unsprung mass
  • Adaptation of the spring characteristic by spring geometry
    and fibre layout
  • Optimized corrosion and damping properties
