Abstract: The bond strength between thermoplastic extruded poly(vinyl chloride) tube and hydroxyl-terminated poly(butadiene)-based composite rocket propellant was studied in this paper. Assessment of bond strength was carried out quantitatively, based on strength determination using specific method and qualitatively, based on cohesion energy of tested materials. Inhibited cartridge loaded propellant grain, after conditioning at ambient temperature, gave a successful performance during static evaluation.

Keywords: Poly(vinyl chloride), hydroxyl-terminated poly(butadiene), bond strength, cartridge loaded grain.
