摘要
Abstract
The motor propellants which were stored for two years, five years, eight years and ten years were selected as reasearch specimens to study the mechanics properties of solid-rocket-motor hydroxy-terminated polybutadiene binder (HTPB)propellant during the full service life. The mechanics properties were verified tested by stress relaxation test and bend fraction test of propellant specimens. The reasearch results showed that relaxation moduli of propellant increasingly went up and fraction toughness went down with motor store periods increasing.关键词
