Case Bonded System for Composite Solid Propellants
Vesna Rodiæ
The examination results of eleven different liners, based on hydroxyterminated polybutadiene (HTPB), carboxyterminated polybutadiene with and without acrylonitrile (CTPB, CTBN) and seven solid rocket propellant types, also based on hydroxyterminated polybutadiene and on polyurethane polymer (PU), are presented in this paper. Viscosity values, mechanical characteristics (maximum stress and strain at maximum load) and adhesive strength between propellant/liner and metal/liner were determined.
Key words: composite rocket propellants, polybutadiene, polyurethane, liner, adhesion, maximum stress, strain at maximum load.
