湿老化对丁羟推进剂力学性能的影响
Effect of Moisture Ageing on Mechanical Performance of HTPB Propellant
摘要
Abstract
In order to study the effect of moisture ageing on the mechanical performance of HTPB propellant, some moisture ageing tests have been done to HTPB propellant at the temperatures of l0℃ , 30℃ , 50℃ and under different relative humidity. Mechanical performance tests have been done for the moisture ageing samples. The action of temperature during the moisture ageing has been discussed. The effect of relative humidity on the speed of moisture ageing and on the mechanical performance reduction has also been discussed. Results indicate that the mechanical performance becomes weaker and weaker with the increase of moisture ageing time. The degressive speed of relative tensile strength σm/σmo becomes faster and the degressive degree of σm/σmo becomes bigger in the high relative humidity than those in the low relative humidity when the temperature is same. The degressive speed of σm/σmo becomes faster in the high temperature than that in the low temperature when the relative humidity is close.关键词
