Abstract:

Experiments have been conducted in order to see if internal grooves in steel cylinders will lead to higher bond strengths produced by the GLEEM Gun Liner Emplacement with an Elastomeric Material process. Groove depth and twist angle were varied. Both experimental and analytical studies showed that at the pressures used, there was little movement of the liner material into the grooves. However, the liner was seen to conform to very small machining marks in the steel cylinder inner bore, providing an increase in the coefficient of friction. A second significant finding was that using Teflon Teflon is a registered trademark of DuPont Corp, Wilmington, DE as the elastomer reduced the friction between the elastomer and liner, giving a more even pressure distribution along the length of the cylinder.
