| 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.

We claim:
1. An archery bow, comprising a handle section; a pair of bow limbs attached to and extending outwardly from the handle section to provide a pair of spaced limb tips, each limb having a side adapted to face the archer and a side adapted to face away from the archer when the bow is in use, and each limb including a core of a syntactic foam material, a strip of tension material intimately secured along its length to the core along the side of the limb adapted to face away from the archer, and a strip of compression material intimately secured along its length to the core along the side of the limb adapted to face the archer; a bowstring; and means coupling the bowstring to the limb tips.
