Patent attributes
An archery bow comprises a central riser, first and second bow limbs attached to the riser, and a draw cable coupled to the bow limbs. Each bow limb comprises a multilayer composite structure having a compression layer, a tension layer, and an intermediate layer between the compression and tension layers, with the limbs arranged so that drawing the bow causes each limb to bend toward its corresponding compression layer. Each layer comprises corresponding fibers embedded in a corresponding polymer matrix. Elastic moduli of the compression and tension layers are each smaller than that of the intermediate layer. A method comprises attaching the first and second bow limbs to the riser and coupling the draw cable to the limbs. Another method can further comprise forming each bow limb by embedding the corresponding fibers of each layer in the corresponding polymer matrix, and curing the corresponding polymer matrix.
