Structure and Performance of Small-bored I ndustries Molded Combustible Cartridge Case
摘要
Abstract
In order to improve the burning-off property,three small-bored combustible cartridge cases with energetic fibers were prepared by pulp molding method based on basic formulation. The pore structure, combustion performance,mechanical characteristics and ballistic property were analyzed by the instrusion porosimeters,the closed-bomb tests,the mechanical tests and the shooting tests.Results show that pores of combustible cartridge case are mainly slit-shaped and wedge-shaped,and pore size distribution is scattered.The porosity of combustible cartridge case is over 25%.The pore volume of combustible cartridge case is above 0.25 cm3/g,and the specific sur-face area is about 20 m2/g.Cigarette sensitivity of combustible cartridge case with heat-resistant coating is above 6 s at 400℃.The small-bored combustible cartridge case with the energetic fibers is beneficial to increase the porosity and the burning rate,shorten the constant volume combustion time and improve the burn-off properties.In shooting tests of charge,the ballistic property of the mixed charge of combustible cartridge case can be improved by adding energetic fibers.关键词
