Rheology of suspensions with aluminum nano-particles [PDF]
, 2009 Nano-scale aluminum particles are innovative materials increasingly used in energetic formulations. In this contribution, the rheological behavior of suspensions with either paraffin oil or HTPB as the matrix fluid and nano-scale aluminum (ALEX) as the ...

Experimental study on the porosity of HTPB propellant: characterization of damage evolution
Journal of Materials Research and TechnologyTo characterize the damage evolution mechanism of HTPB composite solid propellant, the porosity as well as the sphericity will be analyzed using micro-CT. Under normal temperature and pressure, the damage mechanisms include voids, ''dewetting'' damage at

Mechanical properties of HTPB composite propellants in the initial period of service life [PDF]
Scientific Technical Review, 2014 Uniaxial tensile tests of different composite solid rocket propellant compositions, based on hydroxyl-terminated polybutadiene (HTPB), have shown that mechanical properties extensively change after curing, up to 100% of their initial values, during the ...

The Synergistic Effect of Fe-Based MOFs and HTPB on AP Decomposition in Solid Propellants
SolidsMany factors and their mutual interaction between catalysts and AP/HTPB composite solid propellant induce the complexity in the combustion. Among them, we prepared two Fe-based MOFs as catalysts and investigated their catalytic effects and mechanism on ...
