The results of research of cast composite explosives based on octogene and polyurethane binder (PBX) containing aluminium are presented. Influence of Al and HMX content and particle dispersion on rheological, physical-chemical, mechanical and explosive characteristics of PBX is investigated. It was established that the presence of metal powder has a significant effect on composite explosives' characteristics, especially on detonation wave parameters. The PBX detonation velocity and pressure, as well as the particle velocity and shock sensitivity are reduced and chemical reaction zone width and duration are increased with increased content of aluminium.
Key words: cast explosives, composite explosives, octogene, polyurethane binder, aluminium, detonation parameters.
