An inv estigation on interfa cial interaction of AP and T ris-(۲-hydroxyethyl)-isocyan uratevia F T-IR and FT-Ram an

Composite propellan ts are nonhomogeneous propellants and comp rise primar ily crystalli ne oxidizers and metal fuels unifor mly suspended in a resin binder. The crystalline oxidizers are usually inorganic compounds, s uch as ammonium perchlorate (AP ) or potassiu m nitrate but can also be organic, for example cyclotrimethylenetrinitr amine (RD X) or cyclotetramethylenetetramine (H MX). The h igh solid loading requires an interaction betwee n the bind er and the filler in orde r to prevent dewetting, i.e., separation around a particle of filler. If dewetting o ccurs between the binder and filler, the flame front propaga tes below t he burning surface to produce a more rapid combustion of the pro pellant [۱]. Attempts to improve the binder- filler interaction in com posite propellants have included th e addition of bonding agents. A b onding agent produces an interactio n between th e oxidizer crystal and t he binder b y forming either primary or secondary bonds w ith the oxi dizer and a primary bon d with the binder. Bonding agent by producing chemical or physical bond between binder an d oxidizer, prevent de wetting and improve me chanical and aging properties [۲]. In our studies FT-IR and FT-Raman were used to study the interaction betwee n Tris-(۲-hydroxyethyl)-isocyanurate as a bo nding agent and AP.
