ABSTRACT:
A laminated archery bow limb has a relatively light weight core consisting of a plurality of hollow micro spheres in a matrix of hard synthetic resin and formed as a tapered strip of "syntactic foam" material with relatively thin facing and backing strips of high tensile and compressive strengths and a high rate of recovery glued to opposite sides thereof. In a second form of bow limb construction the core material further includes, in addition to the hollow micro spheres, reinforcing fibres to increase the physical strength thereof.
