Abstract:
The object of this study was to develop a closing plug which would close off a propellant cartridge case, and allow no leakage of propellant be structurally resistant to impact loading and act as a centering device for the semifixed projectile break up completely on firing and utilize the best non-critical structural plastic materials compatible with maximum economy. A functional and structural study was conducted, and a number of design and material variations were developed. Plugs molded from phenolics reinforced with various materials-woodflour, cotton flock-rubber, chopped cotton fabric, and chopped glass fiber-were investigated. A closing plug made of a chopped cotton fabric reinforced phenolic material, was considered to most nearly meet the design and development objectives. Author
