Sažetak
U radu je razmatrana mogućnost korišćenja termoplastičnog materijala kao inhibitora za čvrsto gorivo u dužem vremenskom periodu. Osnovna tačka ovog razmatranja je analiza karakteristika spoja ekstrudirane PVC cevi i livenog HTPB/IPDI raketnog goriva ispitanih odmah posle izrade uzoraka i posle dužeg vremena skladištenja. Struktura poli(vinil hlorida), tehnologija ekstruzije, hidroksi terminiran polibutadien i tehnologija livenja su opisani. Ispitane karakteristike uzoraka spoja ekstrudirana PVC cev-liveno HTPB/IPDI gorivo su jačina spoja i vizuelni izgled razdvojenih delova. Određivanje jačine spoja i vizuelnog izgleda pomenutih spojeva izvršeno je na temperaturama 20oC i 50oC. Ove karakteristike spoja ekstrudirana PVC cev-liveno gorivo na bazi HTPB/IPDI su određene kod sveže pripremljenih uzoraka i kod uzoraka posle pet godina skladištenja u magacinskim uslovima na obe gore navedene temperature.
