Abstract
A bow limb which is totally molded essentially filled with unbroken longitudinal strands of fiberglass oriented in the central configuration in parallel strands, but as approaching the exterior of the bow, the strands conform to the exterior configuration of the limb. The bow limb is also characterized by a substantially constant cross-section even though width and thickness may vary longitudinally. This maintains a constant ratio of resin to fiberglass which is important to insure uniform strength characteristics. If the concentration of resin to fiberglass becomes too great, a brittle or weak point which invites breakage can occur. If the fiberglass to resin ratio is too great, inadequate bonding can result in bending failure.
