Smith, Paul C.;Huf, Joel P.;Williams, Christopher A. published 《Rocket Propellant Comparison: Conventional Planetary Mixing and Resonant Acoustic Mixing》 in 2022. The article was appeared in 《Propellants, Explosives, Pyrotechnics》. They have made some progress in their research.Related Products of 119-47-1 The article mentions the following:
A standard HTPB/AP/Al composite rocket propellant formulation was prepared with a conventional vertical planetary action mixer and resonant acoustic mixer (RAM). Ingredients and process conditions were standardised as much as possible to facilitate a direct comparison of the two process regimes. Cured propellant specimens were characterised for sensitiveness, ballistic properties and mech. properties at 3 temperatures (-54°C, 25°C and 74°C). No significant differences were noted for sensitiveness between the planetary and RAM mixes. A slightly lower burn rate at 1000 psi (6.89 MPa) was noted for the RAM mixes. Maximum stress results at 25°C were similar but significant differences in maximum strain and modulus were recorded. Maximum strain for the 1 Pt, 2 Gal and RAM were 7.4%, 9.1% and 17.6%, resp. Modulus results were 26.0 MPa, 19.3 MPa and 11.1 MPa, resp. Similar improvements in strain capability for the RAM propellant were recorded at -54°C and 74°C, with increases of 66% and 117%, resp. A greater strain capability results from stronger interfacial adhesion between the solid fill and the binder, which is in turn generally a result of improved wetting of solid particles. This result, therefore, indicates more thorough mixing in the case of the RAM process but this requires confirmation through a more direct examination of the underlying mechanism. And 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) was used in the research process.
