Study on Rate-Dependent Characteristics of “Dewetting” Point of Composite Solid Propellant [PDF]
Hangkong bingqi, 2023 “Dewetting” can happen between solid particles and matrix of solid propellant during loading process. The strength and elongation at “dewetting” point are directly related to loads. The study based on the stress-strain response curve characteristics of a

Experimental and simulative thermal stability study of HTPE solid propellants in different scales
Case Studies in Thermal Engineering, 2021 The hydroxyl-terminated polyether (HTPE) solid propellants are widely recognized as promising alternatives for hydroxyl-terminated polybutadiene (HTPB) propellants due to their compliance with insensitive munition characteristics of composite solid ...

Rubber Chemistry and Technology, 2019 ABSTRACT Solid propellants are energetic materials used to launch and propel rockets and missiles. Although their history dates to the use of black powder more than two millennia ago, greater performance demands and the need for “insensitive munitions” that are resistant to accidental ignition have driven much research and development over the ...
