Ageing studies on AP/HTPB based composites solid propellants
Energetic Materials Frontiers, 2021 Components of solid rocket motor that are susceptible to ageing are propellant, insulator, inhibitor, interfaces, igniter system, and seals. Seals, insulator, ignition systems are replaceable but the motor would be recast when the deterioration in ...

Preliminary research of composite rocket propellants including octogene [PDF]
Scientific Technical Review, 2017 Composite solid propellants based on ammonium perchlorate/hydroxyterminated polybutadiene/isophorone dyisocyanate including different contents of octogene (HMX) have been represented in this paper. The mass of HMX increased in relation to oxidant, with constant bimodal fraction ratio.

Bonding agents for composite rocket propellants [PDF]
Vojnotehnicki glasnik, 2003 The paper analyzes the effects of bonding agents on mechanical properties and viscosity of composite rocket propellants based on hydroxiterminated polybutadiene and toluendiizocyanate, i.e. izophorondiizocyanate. The efficiency of bonding agents (BA) of different structure has been compared including triethylentetramine (TET), tris-(2-methyl ...
