摘　　要：为解决航天领域优选材料的难题,针对航天器用材料服役环境特点及材料自身性质,分别从材料性能、工艺、服役环境和安全四个方面构建了航天器材料应用验证评价的技术指标,通过层次分析法(AHP)和熵权法建立航天器材料应用验证量化评分模型,并以两批次航天器用涂覆材料为例,通过AHP-熵权组合赋权,将主观和客观方法相结合,确定了涂覆材料的综合权重,最后利用模糊综合评价的方法对两批次航天器涂覆材料的性能进行了评分比较,实现了材料综合性能的量化打分。In order to solve the problem of selecting spacecraft materials,according to the working environment characteristics and properties of spacecraft materials,an index system for the applicability evaluation of spacecraft materials is established from the four aspects:functional stability,process applicability,environmental adaptability and service safety.The comprehensive evaluation model of spacecraft materials application validation is established through analytic hierarchy process(AHP)and entropy weight method.Two batches of coating materials for spacecraft are taken as examples,the comprehensive weight is determined by combining the subjective and objective methods through AHP-entropy weight combined method.Finally,the properties of two batches of spacecraft coating materials is scored and compared by using the fuzzy comprehensive evaluation method.
