Research, test and evaluate fireproof materials for mixed solid fuels operating reliably in the temperature range -50÷50oC
Keywords:
flame retardant shell, mixed solid rocket fuel, nitrile butadiene rubber, temperature range -50÷50oCAbstract
This article presents experiment results on the manufacture of the flame retardant sheath for the based-rubber solid fuel bar-nitrile butadiene rubber NBR26. The flame retardant sheath is specified by high mechanical strength (tensile
strength 19.2 MPa), good solvent resistance (swelling capacity in toluene 19.5%), good heat and cold resistance ensuring the working capability of the mixed solid fuel bar in the temperature range (-50÷50oC). The product’s calorific effect is high (over 3000oC) during the period of up to 12 s according to the design document. The results of this experiment play an important role in the development of the rocket industry in general and the mixed rocket solid
fuel industry in particular in Vietnam in the next period.
