Investigation of Fracture Criterion for HTPB Propellant

Advanced Materials Research, 2012
The fracture toughness of HTPB propellant has a significant rate effect. In order to establish a fracture criterion considering rate effect for HTPB propellant, experiments were conducted at different loading rates. Two kinds of specimens were used to get the fracture properties.

Chemistry and kinetics of hydroxyl-terminated polybutadiene (HTPB) and diisocyanate-HTPB polymers during slow decomposition and combustion-like conditions

Combustion and Flame, 1991
Abstract The decomposition chemistry and kinetics of hydroxyl-terminated polybutadiene (HTPB), hydroxyl-terminated polyethyleneglycol adipate (HTPA), and diisocyanate cross-linked HTPB (diisocyanates = TDI, IPDI, and DDI) were determined by TGA, DSC, and IR spectroscopy at 10°C/min and by SMATCH/FTIR at 250°–350°C/s. At 10°C/min, the first step (300°–

Flame structure of ADN/HTPB composite propellants

Combustion and Flame, 2001
Abstract Visual flame characteristics, burning rates, and final flame temperatures for propellants based on ammonium dinitramide (ADN) and hydroxyl-terminated polybutadiene (HTPB) at different HTPB concentrations (3–20%) have been studied at pressures of 0.05 to 0.6 MPa.

Development of HTPB Propellant for Ballistic Missiles

1974
Abstract : The program objective is to develop a family of solid propellants for ballistic missiles based on an HTPB (hydroxyl terminated polybutadiene) binder, and to demonstrate one optimized propellant formulation by large scale motor firings. Specifically, five propellants have been formulated and are being characterized to the point that they will

Oscillatory combustion of fine-AP/HTPB propellants

36th AIAA Aerospace Sciences Meeting and Exhibit, 1998
The steady and oscillatory combustion of wide distribution AP/HTPB composite propellants containing coarse AP and fuel-rich, fine-AP/HTPB pocket regions is being investigated experimentally and theoretically. These propellants are of special interest because they are similar to many wide distribution bi-modal tailorable plateau propellants.

HTPB-based polyurethanes. II. SINs with PMMA

Journal of Polymer Science Part B: Polymer Physics, 2000
Simultaneous interpenetrating networks from poly(methyl methacrylate-co-ethyleneglycol dimethacrylate) (PA) and a hydroxyl-terminated polybutadiene-based polyurethane (PU) were prepared with various hard-segment contents (X) in the PU and different ratios (PU/PA) between the components. The level of the reinforcement, the mechanism of molecular failure,

Noncovalent Interactions Define Global Properties of HTPB Isomers

The Journal of Physical Chemistry B
Commercially available hydroxyl-terminated polybutadiene (HTPB) variants [containing various percentages of its isomers (cis, trans, and vinyl) and utilized in numerous applications ranging from rocket propellant binders to automobile tires] exhibit differences in their thermomechanical properties.
