EFFECTS OF CL-20 ON THE PROPERTIES OF GLYCIDYL AZIDE POLYMER (GAP) SOLID ROCKET PROPELLANT

摘要

The microstructures and granularity distributions of HMX and CL-20 particles were analyzed. Three industrial and research-type GAP-based solid propellants containing CL-20 particles, featuring the same nominal composition, were prepared and experimentally tested. The effects of CL-20 particles on the theological properties, energetic properties, and the hazardous properties of GAP-based solid propellants were investigated. The properties mentioned above were also compared to those propellants containing HMX. Also, the strand burning rate and the associated combustion properties of propellants were determined. It turned out that the GAP-based propellants containing CL-20 particles can be prepared and cast safely. GAP-based propellants containing CL-20 particles are more sensitive to impact and friction compared to propellants with HMX. However, the addition of CL-20 particles to the propellant formulation can increase the burning rate and affect the combustion behavior, when compared to the reference propellant.
