摘要
Abstract
The aging properties of double-base propellant H01 under 65℃ were measured by a dynamic mechanical analyzer. In lower temperature range -10～40℃,the values of loss tangent tanδ decrease obviously and the peaks of β relaxation become more clear with increasing the aging time. The changes of the peak temperature of tanδ at α relaxation, values of dynamical compliances J′ and J″, and superposition vertical shift factors of master curves of storage modulus E′,loss modulus E″, J′ and J″ for DB propellant H01 with aging times are regular. The TG-DTG test results show that the mass-loss of samples at 183℃ decreased as the aging time increased, indicating that the contents of the plasticizer in DB propellant H01 decreased as the aging time increased. Therefore, it is shown that the decrease in the plasticizer must also be a main reason to lead to the decrease in above-mentioned "mechanical loss", except for the "physical aging" resulting from the structural relaxation.关键词
