Zusammenfassung:	A lightweight shaft 22 includes a plurality of non-metallic fibers 42, 63, 66 and 70 arranged in prescribed orientations from one end of the shaft to the other and carried by a cured plastic material 103. Additional fibers 82 and 84 are carried by the cured plastic material 103 and are located at a butt end 28 of the shaft 22 to form a strengthening band 104 which precludes splitting and cracking of the shaft at the butt end. A lightweight filler element 106, which is composed of a rigid foam material, is located within a portion 27a of an opening 27 at a tip end 30 of the shaft 22 to strengthen the tip end.
