“…It has a low temperature of decomposition and a relatively high heat of combustion which is favorable for ignition and sustained combustion. It has a higher glass transition point compared to other commonly investigated solid fuels, like HTPB, which makes it stronger but also makes it more brittle [31,32]. PMMA is also naturally transparent when cast and machined, which has led to it being used for partially optical investigations of combustion processes in hybrid rockets without sacrificing the standard center-perforated, axisymmetric, fuel grain design [33].…”

“…It can also be extruded into a filament suitable for 3D printing; however, this causes it to lose its transparency preventing optically accessible investigations through the fuel grain [34,35]. Commercially available PMMA is found to have some variability, which could result in some experimental inconsistencies [32].…”

“…Outros aspectos comparativos entre o PBLH e os polietilenos serão abordados adiante. O polimetacrilato de metila (PMMA) também tem sido estudado como combustível na propulsão híbrida (JENS et al, 2018;KARABEYOGLU, 2017;LOHNER et al, 2006;RABINOVITCH et al, 2018). 2002d, 2002a, 2002bSUTTON;BIBLARZ, 2017).…”

“…Especificamente, polietilenos de baixa densidade de índices de fluidez distintos, mas da mesma ordem de grandeza, produziram, em composições binárias com parafinas macrocristalinas, valores razoavelmente distintos para as temperaturas dos picos endotérmicos de fusão em ensaios DSC executados sob as mesmas condições experimentais (KRUPA; MIKOVÁ; LUYT, 2007; MOLEFI; LUYT; KRUPA, 2010). WERNIMONT; HEISTER, 2000), com a observação de Winters acerca da comercialização expressiva de blendas poliméricas sob o rótulo de um determinado polímero (WINTERS, 2012), bem como, com os comentários de Rabinovitch et alquanto à variabilidade de tipos de PMMA ofertados no mercado(RABINOVITCH et al, 2018). Em resumo, o panorama geral apresentado sugere que a interpretação dos resultados obtidos nestes estudos está necessariamente atrelada à variedade específica do polímero utilizado.A cristalinidade, a temperatura de fusão e o comportamento mecânico de composições entre polietilenos e parafinas parecem guardar relação com sua miscibilidade.…”
