Abstract: Pressed composites of TATB (2,4,6‐trinintro‐l,3,5‐benzenetriamine) undergo irreversible volume change when subjected to thermal cycling. Using micro x‐ray computed tomography and ultra‐small angle neutron scattering, we have characterized the micro‐structure of as‐pressed and ratchet grown specimens of PBX 9502, a TATB‐based composite, thereby distinguishing the effects of ratchet growth from the effects of density alone. Porosity differences are shown to effect mechanical properties, presented here, with ongoing efforts to evaluate sensitivity and/or performance effects.
