Abstract:
A fiber-reinforced plastic leaf spring and a method for producing the fiber-reinforced plastic leaf spring are provided, which is suitable in particular for use in a motor vehicle. It has an elongate leaf spring main body which comprises a first eye bushing at a first end and a second eye bushing at a second end. The leaf spring main body and the first and second eye bushings are formed using at least a first layer and a second layer of a composite material. Each of the layers is guided along a centerline of the leaf spring main body to form the leaf spring main body and, to form the first and second eye bushings, is respectively wrapped around a bushing element having a first center axis and around a bushing element having a second center axis.
