Abstract
A carbon fiber firearm stock, and methods and apparatus for making a carbon fiber firearm stock, including a molded heat-expandable foam core and layer(s) of carbon fiber material molded on the foam core. Expansion of the heat-expandable foam forces the carbon fiber material into apposition with the mold to transfer fine detail areas of the mold to the surface of the carbon fiber firearm stock.
Claims19
A method for manufacturing a carbon fiber firearm stock, comprising:
- placing one or more heat-activated pieces of foam in a foam core mold;
- heating the foam core mold to a first temperature for a first time to generate a foam core;
- removing the foam core from the foam core mold;
- laying up the foam core with heat activated carbon fiber layers to create a carbon fiber laid-up foam core;
- placing the carbon fiber laid-up foam core into a carbon fiber mold;
- and
- heating the carbon fiber mold to a second temperature for a second time to generate the carbon fiber firearm stock.

A method of manufacturing a carbon fiber firearm stock, comprising the steps of:
- placing heat-expandable foam material in a first mold;
- heating the heat-expandable foam material in the first mold for a controlled first time and first temperature to expand the heat-expandable foam material to form a foam core;
- cooling the first mold and removing the foam core from the first mold;
- laying up pieces of fiber-reinforced sheet material on the foam core and positioning in a second mold;
- heating the fiber-reinforced sheet material on the foam core in the second mold for a controlled second time and second temperature to further expand the foam material and press the fiber-reinforced material into apposition with the second mold to shape the fiber-reinforced material according to the shape of the second mold and coalesce the fiber-reinforced sheet material together on the foam core to form a firearm stock;
- and
- cooling the second mold and removing the firearm stock from the second mold.
4 more elements
A firearm stock comprising:
- a heat-expandable foam core;
- and
- a carbon fiber shell disposed on the heat-expandable foam core.
