CHARACTERIZATION AND EVALUATION OF LIGHT METAL HYDRIDES.

Abstract

Evaluation of a light metal hydride in CMDB propellants was continued. Distinct improvements in processibility were observed with recent batch production lots. By contrast, the laboratory scale continuous process to- date has produced a material that is more difficult to process but expected to afford higher combustion efficiency. Evaluation of these materials in combination with P-BEP/TVOPA binders was hampered by difficulties in achieving reproducible cure. These difficulties were overcome by pretreatment of the prepolymer, and by changing the mode of cure catalyst addition. A theoretical- experimental program upon the shelflife of LMH propellant was completed. Reasonable agreement between observed and predicted failure times was obtained and estimates of motor shelflife were made. (Author)
