A Study on Creep Behavior of Composite Solid Propellants
and antioxidant. Each of the components contributes something to the final binder characteristics. Once cured, the binder makes the composite propellant flexible, which decreases the likelihood that the propellant will fracture under stress and pressure. The mechanical properties of solid rocket propellants are very important

Study On The Aging Properties And Storage Life Prediction
It is found that the Antioxidant H is composed of N-N'-Diphenyl-p–phenylenediamine (DPPD) and its oxidation product N-N'-Diphenyl-p-benzoquinone diimines ( DPBQ). The changing rule of the content of them was obtained.It is approved that the antioxidant H can react with toluene diisocyanate(TDI) in HTPB propellant.

SOLID PROPELLANTS - arXiv
Presently, solid propellants are used for the launch systems of many civilian and military rockets,7 mainlybecause of their greatersafety andreliability in comparison with liquid fuel. Early booster charges were relatively small (,30 kg); in comparison, each booster on the Space Shuttle had 500 000 kg of solid propellant.

Effects of Antioxidant on Properties of HTPB-IPDI High
The effects of antioxidant H (N, N-diphenyl-p-phenylene diamine and 4426-S (sulfurized di- (3, 5-di-tert-butyl-4-hydroxylbenzyl) ) on rheologic and mechanical properties of HTPB/IPDI propellant with highburning rate is studied. The results show that the apparent viscosity of proPellant slurry with antioxidant Hincreases, shear rate exponent reduces, but the flowability and leveling of ...
