| 摘要： | Uniaxial compression testing at high strain rates was performed on several lots of RPD-596 gun propellant with varying processing technique for manufacturing nitrocellulose, and the sourcing of those materials, to evaluate the behavior under loading at various temperatures. Experimental lots of RPD-596 gun propellant grains were manufactured, substituting the traditional method of sulfite cellulose with the kraft process, for producing kraft cellulose. Additional source materials of wood pulp were used to evaluate the material behavior under compression at a high strain rate. Gun propellants are subject to harsh and extreme conditions during the initial launch process for munitions. Testing on specimens were conducted at strain rates on the order of 200/s and temperatures ranging -45, -32, 23, and 63C. |
