Experimental characterization and numerical modeling of additive-manufactured composite solid rocket propellant with anisotropic density
Additive manufacturing (AM) allows for fabrication of functionally-graded energetic materials such as solid rocket propellant. Significant improvements in grain geometry control and burn rate manipulation may be realizable, but new defects unique to AM processes must be characterized to understand their influence on material performance. The objective of this thesis research is to characterize defects in 3D-printed ammonium perchlorate composite propellant (APCP) related to processing conditions and model their effect on deflagration. X-ray photoelectron spectroscopy (XPS) and x-ray computed ...
