Abstract
Description
technical field
[0001] The invention relates to the interaction mechanism of the azide polyether propellant filler-matrix interface, in particular to a method for characterizing the surface and interface characteristics of the azide polyether matrix-filler. Background technique
[0002] Azide polyether propellant is a high-performance solid propellant with high energy, insensitivity, and low characteristic signal. It meets the needs of various advanced missile weapons and is the focus of current research in the industry. PBT propellant is a composite energetic material with polyurethane elastomer as the binder matrix, and the adjustment of mechanical properties has become one of the key technologies in the research and development of this type of propellant. Because the PBT side chain contains a large number of rigid azide groups, the polymer molecular chain is short, the flexibility is poor, especially the low temperature mechanical properties, which have become the technic...
