Stock for a firearm and method of manufacturing a stock for a firearm
A stock for a firearm. The stock includes a foam core, a carbon fiber skin and a carbon fiber insert having a housing for housing the action mechanisms of the firearm. The carbon fiber insert includes a sheet molding compound (SMC) or a bulk molding compound (BMC) that includes a resin matrix and randomly arranged chopped carbon fibers in the resin matrix. The foam core has a cavity in which the carbon fiber insert is housed. The carbon fiber skin covers the foam core and at least part of the carbon fiber insert housed in its cavity, the carbon fiber insert being mechanically bonded to the carbon fiber skin.
1 . A stock for a firearm having action mechanisms for loading and firing projectiles, the stock comprising:
a carbon fiber insert including a housing for housing at least a portion of the action mechanisms, the carbon fiber insert comprising a sheet molding compound or a bulk molding compound comprising a resin matrix and randomly arranged chopped carbon fibers in the resin matrix;
a foam core that includes a cavity in which at least a portion of the carbon fiber insert is housed; and
a carbon fiber skin at least partially covering the foam core and at least partially covering the carbon fiber insert, at least a portion of the carbon fiber insert being mechanically bonded to the carbon fiber skin.
2 . The stock according to claim 1 , wherein the carbon fiber insert includes a perimeter zone that delimits an outer contour of the housing, at least part of the perimeter zone being covered by the carbon fiber skin.
3 . A stock according to claim 1 , wherein the carbon fiber insert comprises aramid fibers blended with the carbon fibers in the resin matrix.
4 . The stock according to claim 3 , wherein the weight ratio of aramid fibers to carbon fibers is at most 1:3.
5 . The stock according to claim 1 , wherein the percentage by weight of the carbon fibers in the carbon fiber insert is 30-50%.
6 . The stock according to claim 1 , wherein the percentage by weight of the carbon fibers in the carbon fiber insert is 35-45%.
7 . The stock according to claim 1 , wherein the carbon fiber skin comprises a plurality of sheet molding compounds comprising a resin matrix and randomly arranged chopped carbon fibers in the resin matrix.
8 . The stock according to claim 1 , wherein the carbon fiber insert and the carbon fiber skin have the same composition.
9 . The stock according to claim 1 , wherein the carbon fiber skin comprises a plurality of meshes comprising dry, woven carbon fibers shaped by resin transmission molding.
