Abstract: In comparison with newly produced emulsified CTPB, pro-pellant containing long-term storage (more than five years)emulsified CTPB was tested with the same propellant formula and under the same enviromen-tal condition for the accelerated aging performance.The performance parameters were measured at room temperature.The results show that under accelerated aging condition(50℃), the maxium tensile strength σm, the maxium tensile strain εm, the break tensile strain εb,and the break work Wb for both propellant are differed from each other, and have similar tendancy of changing with time.
