ABSTRACT:
Composite springs and methods of manufacture are described. The composite springs include a flexible core supporting multiple layers of a cured, resin-impregnated composite fiber wherein resin-impregnated composite fiber is wound or braided over the flexible core and cured on a helical mold to form a spring having a desired helical pitch, diameter and spring rate. The multiple layers of resin-impregnated composite fiber are wound or braided at ±5-90 degrees relative to the longitudinal axis of the flexible core.
