Abstract
A method of forming a carbon fiber rifle barrel may include the steps of heating a barrel core to increase the length of the barrel, placing the barrel core inside a mold and holding the lengthened barrel in place, adding a carbon fiber mix to the mold in which the carbon fiber mix includes a blend of resin and chopped carbon fibers, sealing the mold, curing the carbon fiber mix surrounding the lengthened barrel core in which the cured carbon fiber mix holds the length of the barrel core creating a tension on the cooled barrel core which increases a rigidity of the rifle barrel thereby increasing the accuracy of the rifle barrel, removing the rifle barrel from the mold, and finishing the rifle barrel via grinding to a desired finish.

A method of forming a rifle barrel comprising the steps of:
- heating a barrel core, wherein the heating increases a length of the barrel core;
- placing the barrel core inside a mold and holding the lengthened barrel core in tension;
- adding a carbon fiber mix to the mold, wherein the carbon fiber mix comprises a blend of resin and chopped carbon fibers;
- sealing the mold;
- curing the carbon fiber mix surrounding the barrel core, wherein the cured carbon fiber mix holds the tension on the barrel core, and wherein the tension increases a rigidity of the rifle barrel;
- removing the rifle barrel from the mold;
- and
- finishing the rifle barrel via grinding to a desired finish.
A method of forming a rifle barrel comprising the steps of:
- heating a barrel core to grow a length of the barrel core;
- placing the barrel core or a mandrel comprising the barrel core inside a mold;
- holding the length of the heated barrel core in place;
- adding a carbon fiber mix to the mold to surround the barrel core, wherein the carbon fiber mix comprises a blend of resin and carbon fibers;
- sealing the mold;
- curing the carbon fiber mix, wherein the cured carbon fiber mix holds the length of the barrel core in place causes a tension on the barrel core when the barrel core cools, and wherein the tension increases a rigidity of the rifle barrel;
- removing the rifle barrel from the mold;
- and
- finishing the rifle barrel via grinding to a desired finish.
A method of forming a rifle barrel consisting of:
- heating a barrel core to grow a length of the barrel core;
- placing a barrel core inside a mold and holding the heated barrel core length in place;
- adding a carbon fiber mix to the mold, wherein carbon fiber mix surrounds the barrel core wherein the carbon fiber mix comprises a blend of resin and carbon fibers;
- sealing the mold;
- curing the carbon fiber mix, wherein the cured carbon fiber mix holds the length of the barrel core creating a tension on the barrel core when the length of the barrel core decreases due to cooling, and wherein the tension increases a rigidity of the rifle barrel;
- removing the rifle barrel from the mold;
- and
- finishing the rifle barrel.
