An archery bow having limbs (l2, l4) constructed of laminae (36, 38, 40, 42, 44) of pre-stressed fibers (45, 59, 63) in a resin matrix, all of the laminae of the bow limb over at least a substantial intermediate portion of the length of the limb being pre-stressed and all of the laminae, as well as riser wedge (22) and tip wedge (26) portions of the limb, being adhesively interconnected in a pre-stressed configuration by an efficient adhesive. The limbs are free from any core of material which is not pre-stressed. One of the layers of material utilized in construction of the limb may contain layers of parallel pre-stressed fibers (59) diagonally oriented with respect to the longitudinal axis (46) of the bow limb and additional parallel pre-stressed oppositely diagonally oriented fibers (63), in order to stabilize the bow limb against twisting during use. |
