SIMPLIFIED METHOD FOR THE PRODUCTION OF A SUSPENSION SPRING MADE FROM A COMPOSITE MATERIAL

摘要

The invention relates to a method for the production of a suspension spring for a motor vehicle, made from a composite material including fibres and resin. According to the invention, the method comprises the following steps, performed on a single production line, namely: production of a central core (2) to support the fibres; production of a yarn comprising at least one layer of fibres wound around the central core (2); and shaping of the yarn around a rotating mandrel (5), drawing the wire as it is being shaped and solidifying same in a helical shape.
