摘要
Abstract
GAP-based high-energy propellant is an important member of solid propellant family.The ageing studies of GAP high-energy propellant containing CL-20/HMX were carried out by high-temperature accelerated aging test.The results show that the modulus of the propellant is significantly increased,while the elongation at break decreases with aging.The density of the propellant decreases,but the burning rate increases with the aging process.The aged propellant was characterized and analyzed by using SEM, XRD,gel fraction,crosslinking density,and HPLC et al.It reveals that CL-20 and HMX could dissolve and migrate in nitric ester and forming CL-20/HMX co-crystal,which is dominant phenomenon in the degradation of aging properties of the propellant.关键词
