Method of forming carbon fibers having internal cavities

A method of forming carbon fibers having internal cavities. The method includes applying a polymer material to a tooling component to form carbon fiber precursor hollow tubes, oxidizing the carbon fiber precursor hollow tubes, and carbonizing the carbon fiber hollow tubes to form carbon fibers, each...
