Abstract

See full text

The present invention relates to a method and an assembly for manufacturing a leaf spring from a fiber-composite material. To this end, tape material from a fiber material, which has been pre-impregnated with a matrix resin, for manufacturing a semi-finished leaf spring is wound under tension onto a winding core, wherein at least two cavities for shaping are configured on the winding core. The tape material here is pressed on by way of a contact pressure means, such that adjacent layers of the fiber material are adhesively interconnected and air pockets are removed. The semi-finished leaf spring under impingement by pressure and heat and under curing of the matrix resin is finally processed to form a leaf spring.
