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
