Experimental and simulation study on micro damage of HTPB propellant under multi angle tensile shear loading

Polymer Testing
The damage evolution of composite solid propellants is influenced by the stress state. In order to investigate the in-situ damage evolution mechanism of hydroxyl terminated polybutadiene (HTPB) propellant under tensile shear conditions, computer ...

Hydroxy-terminated polyether binders for composite rocket propellants [PDF]

, 2007
Propellants based on cross-linked Hydroxy Terminated PolyEther (HTPE) binders are being used as alternatives to Hydroxy Terminated PolyButadiene (HTPB) compositions. HTPE propellants have similar mechanical properties to HTPB propellants but they give

Investigation of hydroxyl-terminated polybutadiene propellant breaking characteristics and mechanism impacted by submerged cavitation water jet

Defence Technology
A submerged cavitation water jet (SCWJ) is an effective method to recycle solid propellant from obsolete solid engines by the breaking method. Solid propellant’s breaking modes and mechanical process under SCWJ impact are unclear.
