Moisture And Temperature Ageing On htpb Based Propellants Binder

Macromolecular Symposia, Volume 414, Issue 3, June 2025.
Abstract This study reports the impact of temperature, oxygen, and humidity ageing on the mechanical properties of a crosslinked hydroxy‐terminated polybutadiene (HTPB) network. Its mechanical behavior is described using a classical Mooney‐Rivlin model and shows a slight crosslinking reaction possibly due to oxidation of HTPB.

Influence of AP Particle Size on Burning Characteristics of HMX/AP Propellants Supplemented with Fe2O3

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 6, June 2025.
ABSTRACT Nitramine propellants have attracted considerable attention in the domain of solid rockets and gun propulsion because of their energetic and smokeless features. Ammonium perchlorate (AP) is the widely used oxidizer in propellants owing to the excellent burning characteristics.
