Abstract:
In view of the mechanical performance anisotropy caused by adopting gel-diractional-pressing-elongation technics in the process of manufacturing propellant,the cause,differential degree and possible solutions to the anisotropy are studied in this paper.The axial and radial anti-tensile intensities of homemade flat propellant sticks are tested at different temperatures.The interior micro-structure of propellants is studied through SEM testing.The analysis of the reason of causing the mechanical performance anisotropy of propellants shows that: when the radial intensity has only 1/3~1/4 of the axial intensity,the anisotropy occurs.Several possible solutions to improving mechanical intensity anisotropy of propellants are proposed.
