复合推进剂力学性能与吸湿率的相关性研究

对复合推进剂试样进行了10℃、30℃、50℃三种温度、多种相对湿度条件下的湿老化,测量了不同条件的湿老化后推进剂试样的吸湿率和力学性能;分别利用线性模型、指数模型和Prony级数模型等3种数学模型表示了复合推进剂力学性能与吸湿率的相关性,并对模型的优劣及其误差进行了讨论。

Research on the Correlativity between Mechanical Performance and Percent of Moisture Absorption of Composite Propellant

In this paper, some ageing tests were done to composite propellant samples under the condition of 10℃, 30℃, 50℃ three temperature and several humidity. The percent of moisture absorption and mechanical performance of propellant samples that had suffered different ageing condition were tested. The correlativity between mechanical performance and percent of moisture absorption of composite propellant was expressed by three mathematical models which were linear, exponential and Prony progression models. Whether these models were good and what about their error were discussed.
