Abstract:

A castable, energetic, plastic-bonded explosive containing glycidyl azide lymer (GAP) an energetic polymer binder combined with the energetic plasticizers trimethyloethane trinitrate (TMETN) and trimethylene glycol dinitrate (TEGDN) or bisdinitropropyl formal and acetal mixture (BDNPF/A), and the explosive solid cyclotetramethylene tetranitramine (HMX) or cyclotrimethylene trinitramine (RDX) having the desirable mechanical properties, insensitivity, and excellent aging properties at much higher solids loading and thus explosive performance than previous compositions. The invention uniquely combines the high energy of high solids loading combined with energetic polymers and plasticizers to provide the insensitivity of rubbery explosive compositions.
