Abstract:

The extension under constant load of plastic propellant ammonium perchlorate, perhaps Al and a burning catalyst with 10 polyisobutylene binder. Parabolic flow curves have been derived, in agreement with previous parallel-plate plastometer results. The existence of finite yield stresses, of the same order as those measured more accurately by parallel-plate plastometry, has also been established, and the presence of linear shear-hardening confirmed. No evidence of strain-thinning has been found. The limitations of constant-load extensional tests are briefly discussed.
