Abstract:
A composite tube for a gun barrel, comprising:a) an inner tubular metal liner defining a longitudinal bore axis;b) a resin matrix material surrounding the liner, the resin matrix material containing a plurality of elongate carbon fibers, the carbon fibers being aligned parallel with the longitudinal bore axis of the liner, and under compression along the longitudinal axis;c) the liner having a breech and a muzzle ends the breech and the muzzle ends surrounded by the resin matrix material, the gun barrel including a muzzle piece attached to the muzzle end of the liner and a breech piece attached to breech end of the liner to compress the carbon fibers;d) the muzzle piece and the breech piece each having a central core adapted to surround the resin matrix material at the muzzle end and breech end, respectively;whereby any vibrations transmitted along the longitudinal bore axis of the liner are absorbed by the resin matrix material and whereby any vibrations reaching the muzzle piece and breech piece are reflected back into the resin matrix material and there absorbed.
