We have performed a series of thermal and mechanical tests to characterize the high explosive 3,3’-diamino-4,4’-azofurazan (DAAF), as well as the formulated version LAX-133 (97 wt% DAAF and 3 wt% FK-800 binder, now also referred to as PBX 9701; for clarity in this report, we will use the name LAX-133 which is what the formulated material was called at the time this work was performed). Specifically, we have used axially die-pressed cylinders (with no further machining) of neat DAAF and of LAX-133 to make measurements of compressive strength, Brazil disk, coefficient of thermal expansion (CTE), as well as irreversible volume expansion with thermal cycling (ratchet growth).
