Patent ID: 8132562

Claim:
An electromagnetic rail gun comprising: a. a pair of spaced rails defining an elongated bore therebetween and operable for receiving an armature along the length of said elongated bore, said armature having a leading edge and a trailing edge; b. a power supply connected to the spaced rails to provide a current flow path through one of the rails, through the armature, and into the other rail to propel the armature along the elongated bore in the direction of the leading edge of the armature; c. wherein said armature and spaced rails are fabricated from a fiber pre-form that is carbonized and then infused with a carbon matrix, and then carbonized again; and d. wherein this carbonized form is further infused with a carbon matrix and carbonized repeatedly until a pre-defined density is achieved; and e. wherein after said pre-defined density is achieved the carbonized form is heated in a non-oxidizing environment until the carbon transforms to a graphatized structure.
