Abstract
High performance propellants and explosives are based on the binding of energetic crystalline solids within a cured elastomeric polymer matrix in order to impart acceptable insensitivity and good mechanical properties to the material. Most plastic-bonded explosives (PBX) used are based on the inert rubbery hydroxyl-terminated polybutadiene polymer (HTPB). The total energetic density of PBXs may then be enhanced by replacing this inert polymer by an energetic one. Mechanical properties of the material should be remained acceptable with the use of an appropriate plasticizer. The glass transition temperature named Tg of a polymer blend is a representative data and an useful measurement which allows to assess how the polymer “rubbery” is, and as well how the material sensitivity is. This Tg property was predicted by computer modelling, and was also measured experimentally for inert HTPB and energetic GAP polymers.
