SEM images of the tensile fracture surfaces for HTPB matrix composite materials are presented, illustrating the distribution of (a) B particles at a 20% mass loading, (b) B particles at a 35% mass loading, (c) SA@B composite particles at a 20% mass loading, (d) SA@B composite particles at a 35% mass loading, and (e) SA@B composite particles at a 50% mass loading.
