| Summary: | Cased telescoped ammunition designs were developed for the Multi-Role Armament and Ammunition System that employed a composite cartridge case. Three candidate composite material systems are being considered for the application--50% chopped fiberglass/Nylon 12, 30% chopped fiberglass/ULTEM (a registered trademark of GE Plastics Corp.), and a continuous fiberglass/urethane. Each of these material systems was subjected to preliminary mechanical testing in order to characterize their basic material properties and to support finite-element modeling of the cartridge case/gun chamber during the firing cycle. Basic mechanical properties such as stress-strain curves, Poisson's ratio, and residual plastic deformation after unloading were obtained and are presented in this report. |
