Abstract
A hybrid metal and composite barrel assembly for a firearm preferably includes a metal inner barrel liner and a composite outer barrel sleeve. The composite outer barrel sleeve preferably includes at least one layer of woven metal mesh material comprising a plurality of metallic fibers, and at least one layer of carbon fiber material comprising a plurality of carbon fibers. The composite outer barrel sleeve is preferably engaged around the metal inner barrel liner, and optionally incorporates a tensioning nut to retain the sleeve on the liner.
Claims26
A firearm comprising a hybrid composite/steel barrel, the barrel further comprising:
- a metal inner barrel liner;
- and
- a composite outer barrel sleeve, the composite outer barrel sleeve comprising carbon fibers;
- and
- wherein the metal inner barrel liner has an external taper from a larger breech end dimension to a smaller muzzle end dimension, and wherein the composite outer barrel sleeve has an internal taper configured to generally match the external taper of the inner barrel liner and fit in close engagement therewith when assembled, and wherein the composite outer barrel sleeve is adhesively bonded to the metal inner barrel liner.
A firearm barrel comprising:
- a metal inner barrel liner;
- and
- a composite outer barrel sleeve, the composite outer barrel sleeve comprising carbon fibers;
- and
- wherein the metal inner barrel liner has an external taper from a larger breech end dimension to a smaller muzzle end dimension, and wherein the composite outer barrel sleeve has an internal taper configured to generally match the external taper of the inner barrel liner and fit in close engagement therewith when assembled, and wherein the composite outer barrel sleeve is adhesively bonded to the metal inner barrel liner.
A method of fabricating a firearm barrel, the method comprising:
- providing a metal inner barrel liner having an external taper from a larger breech end dimension to a smaller muzzle end dimension;
- providing a composite outer barrel sleeve having an internal taper configured to generally match the external taper of the inner barrel liner;
- and
- assembling the composite outer barrel sleeve over the metal inner barrel liner with the internal taper of the composite outer barrel sleeve fitting in close engagement with the external taper of the metal inner barrel liner.
