1. A composite leaf spring, comprising:
a first bushing tube near a first longitudinal end of the leaf spring;
a second bushing tube near a second longitudinal end of the leaf spring;
a base material comprising a ribbon having a width that defines a width of the leaf spring, the base material having first portions near the longitudinal ends of the leaf spring and a second portion between the first portions, the first portions having a first thickness, the second portion having a second, larger thickness, the base material being wrapped at least partially around the first and second bushing tubes;
a plurality of layers of tension material wrapped around the base material, the tension material comprising a ribbon having a width corresponding to the width of the base material, the tension material defining an outermost layer of the leaf spring, the tension material having warp strands in a longitudinal direction between the first and second longitudinal ends of the leaf spring, the warp strands establishing a majority of a composition of the tension material and
a plurality of layers of intermediate material between the base material and the tension material, the intermediate material comprising a ribbon having a width corresponding to the width of the base material, the intermediate material having warp strands in the longitudinal direction and weft strands at an oblique angle relative to the warp strands of the intermediate material.
