Coating of High Melting Explosive Particles by Nitrotriazolone to Formulate Composite Nanoparticles by Spray Flash Evaporation

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 32-39, December 2025.
ABSTRACT The balance between performance and safety of high explosives is at the heart of the current studies, and new ways of combining safety and performance have hence been elaborated. This study focuses on a mixture of 3‐nitro‐1,2,4‐triazol‐5‐one (NTO) and octogen (high melting explosive [HMX]).

Macro-microscopic study on the damage threshold strain of particle-filled polymer composites

Polymer Testing
During the loading process, particle-filled polymer composites will soften due to damage to their internal microstructure, resulting in a decrease in stiffness, toughness, and strength.

Thermo‐Mechanical Evaluation of Novel Composite Propellant Formulations Based on Styrene‐Ethylene/Butylene‐Styrene Block Copolymer

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 117-126, December 2025.
ABSTRACT Two novel composite propellant formulations have previously been produced from a binder consisting of the thermoplastic elastomer styrene‐ethylene/butylene‐styrene (SEBS) and a solid filler, either ammonium perchlorate (AP) or 1,3,5‐trinitro‐1,3,5‐triazinane (RDX).

Ageing studies on AP/HTPB based composites solid propellants

Energetic Materials Frontiers, 2021
Components of solid rocket motor that are susceptible to ageing are propellant, insulator, inhibitor, interfaces, igniter system, and seals. Seals, insulator, ignition systems are replaceable but the motor would be recast when the deterioration in ...

A Structural Integrity Perspective for the Assessment of Ageing in Composite Solid Propellants

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 10, Page 152-158, October 2025.
ABSTRACT Composite solid propellants (CSPs) are critical materials in the defence and aerospace industries, known for their complex mechanical behaviour and susceptibility to ageing. This study explores the application of Principal Component Analysis (PCA) to discriminate the ageing degradation of CSPs based on structural integrity parameters.

Comparative Assessment of Stabilised Polybutadiene Binder under Accelerated Ageing

Journal of Aerospace Technology and Management, 2016
Polybutadiene elastomers are versitile materials, being employed at several applications from rocket propellant binder to adhesives and selants. The elastomers derived from hydroxyl-terminated polybutadiene (HTPB) are usually stabilised with antioxidants

Recovery of aluminum from composite propellants [PDF]

, 1980
Aluminum was recovered from solid rocket propellant containing a small amount of oxidizer by depolymerizing and dissolving propellant binders (containing functional or hydrolyzable groups in a solution of sodium methoxide) in an alcohol solvent ...

A Critical Review of Limitations and Challenges in Advancement of HNF as a Green Oxidizer for Composite Solid Propellant Formulations

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 7, Page 11-30, July 2025.
ABSTRACT Hydrazinium nitroformate (HNF) is a chlorine‐free, high‐energy oxidizer with promising applications in green propulsion systems. This review examines the thermal decomposition, combustion kinetics, flame structure, and behavior of HNF, while critically evaluating the current body of literature.
