Abstract

A composite/metallic gun barrel (8) is disclosed having a metallic liner (12) and a composite casing (20) formed by groups of fibers (32). In accordance with one application of the principles of the present invention, the gun barrel is formed by alternating first and second groups of fibers (36, 40) wrapped about the liner, the first groups being disposed in a first orientation generally perpendicular to the long axis (A-A) of the liner, and the second groups including one or more layers disposed generally parallel with the long axis of the metallic liner. By controlling the amount of fibers in each group relative to the other group, the coefficients of thermal expansion in the radial direction can be matched to provide a gun barrel having desirable firing characteristics.
