Impact of matrix/filler adhesion on properties on local damage and macroscopic behavior of propellants

With industrial partner Arianegroup, we studied the mechanical behavior of three propellant-like materials. Two materials were made of an inert matrix with about 55% of sifted 250 microns ammonium perchlorate (AP) or RDX particles. The last material was the polymer matrix filled with about 20% of aluminium 3 microns particles and filled with AP fillers. […]
