为改善可燃药筒的燃尽性，在可燃药筒基础配方的基础上添加含能纤维，通过抽滤模压工艺制备了3个小口径可燃药筒，并采用压汞法、密闭爆发器、力学试验与射击试验分别对可燃药筒的孔结构特性、燃烧特性、力学性能、弹道性能等进行了研究。结果表明，可燃药筒的孔结构以狭缝形和楔形孔为主，孔径分布较宽，压汞法测得的可燃药筒的孔隙率大于25％、总孔容超过0．25 cm3／g、比表面积约为20 m2／g。添加耐热涂料后可燃药筒在400℃的香烟感度超过6s。含能纤维有利于提高药筒的孔隙率和能量，燃烧速度增大，并缩短燃烧结束时间，可明显改善药筒的燃尽性。可燃药筒与十九孔火药组成装药的射击试验表明，含能纤维的加入能够提高药筒装药的弹道性能。

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.
