Abstract

Abstract An inhibition technique using a fibre-reinforced plastic fabrication concept has been developed. The polyurethane derived by the reaction of hydroxy-terminated polybutadiene ( htpb), toluene-diisocyanate ( tdi) and butanediol ( bd) as a chain-extender (Formulation-HTPB:TDI: BD::1:3.2:2) has been used as a matrix with reinforcement provided by a rayon thread. The sleeves have been fabricated by a filament winding technique using a collapsible mandrel and serve the purpose of an inhibitor for composite propellants. The chief advantage of this technique is a reduction in inhibition thickness and, consequently, an increase in propellant weight leading to an increase in the range/payload of a rocket/missile.
