Thermal decomposition of HTPB/AP and HTPB/HMX mixtures with low content of oxidizer

Journal of Thermal Analysis and Calorimetry, 2014
In this paper, hydroxyl-terminated polybutadiene (HTPB)/ammonium perchlorate (AP) and HTPB/cyclotetramethylene tetranitramine (HMX) mixtures with low content of oxidizer were prepared, and the thermal decomposition process of these mixtures was investigated with TG-FTIR and Raman spectrum.

Synthesis and characterization of lignin–HTPB copolyurethane

European Polymer Journal, 2001
Abstract Lignin–HTPB copolyurethanes have been synthesized from hydroxyl terminated polybutadiene (HTPB) and varied quantities of lignin and toluene diisocyanate. IR spectroscopy and estimation of isocyanate groups have established the formation of HTPB polyurethane and lignin–HTPB copolyurethane.

HNF/HTPB BASED COMPOSITE PROPELLANTS

International Journal of Energetic Materials and Chemical Propulsion, 2002
In a search for new storable high performance propellants for the European Space Agency (ESA), the solid oxidiser Hydrazinium Nitroformate (HNF) was identified as a very promising ingredient for a new storable composite propellant. Two distinct advantages of HNF based propellants over presently used Ammonium Perchlorate (AP) based propellants rvere the

Rheokinetic modeling of HTPB–TDI and HTPB–DOA–TDI systems

Journal of Applied Polymer Science, 2003
AbstractA study of the effect of temperature on a mixture of polymer and curative in the processing of rocket propellants is reported. Experimental viscosity of a hydroxyl‐terminated polybutadiene–toluene diisocyanate (HTPB–TDI) system was measured using a Brookfield viscometer model DV III.

HTPB Propellant Aging

Journal of Spacecraft and Rockets, 1981
Three HTPB propellants, varying in solids loading from 88% to 91%, were selected and developed for evaluation studies including aging. The 88%-solids propellant was verified to fit a previously developed aging model. The aging model has been further successfully applied to the measured mechanical-property aging data for the higher-solids propellants ...

Synthesis of 5-(dimethylsilyl)pentylalkylferrocene-grafted HTPB (alkylFc-HTPB) via platinum-catalyzed hydrosilylation

Journal of the Iranian Chemical Society, 2017
In this work, at first alkylferrocene derivatives were synthesized according to procedure described in the literature. (5-Chloropentanoyl)ferrocene derivatives were prepared by Friedel–Crafts acylation of ferrocene and alkylferrocene derivatives with 5-chloropentanoyl chloride in dichloromethane, and AlCl3 was used as catalyst.
