Abstract: (308 Views)

One of the most important issues for researchers in the propulsion field is the selection of a suitable stabilizer to maintain the desired mechanical properties and proper propellant One of the most important issues for researchers in the propulsion field is the selection of a suitable stabilizer to maintain the desired mechanical properties and proper propellant performance during storage time. In this research, hardness tests, oxidation induction time and thermogravimetric analysis (TGA) were performed on poly diethylene glycol adipate (PDEGA) elastomer with 0.2 weight percent of three types of stabilizer (2-nitrodiphenylamine (NDPA), N-methyl-4-nitroaniline (MNA) and Centralit I) in the presence of trimethylol trinitrate (TMETN) plasticizer, Triphenyl bismuth catalyst and trimethylolpropane chain extender. The results obtained from the hardness tests showed that the hardness of the PDEGA elastomer including N-methyl-4-nitroaniline stabilizer has decreased by about 68% compared to the elastomer without this stabilizer. Also, oxidation induction time and thermogravimetric analysis showed that the elastomer containing N-methyl-4-nitroaniline stabilizer has more resistance to oxidation and mass reduction than elastomer with another stabilizers and causes a longer storage life.
