航天材料工程学内涵及其体系构建

为应对空间特殊服役环境,航天材料研制、保证和使用单位已在材料设计、材料加工、材料评价和材料使用方面开展了大量工作。在此基础上,本文首先对我国航天材料的选型要求进行了分析,接着对航天材料、航天材料飞行试验、空间材料科学、航天材料空间环境适应性等概念进行了辨析,并提出了航天材料工程学的概念,进而对航天材料工程的各个组成部分的关联性进行了阐述。最后,为满足未来空间技术发展需求,在总结和借鉴国内外航天材料工程发展经验的基础上,从规划、研发、试(实)验、评价、选用、数据服务等角度,设计构建了具有航天领域特色的航天材料工程体系。

Connotation and System Construction of Aerospace Material Engineering

In order to overcome the space service environments, a lot of work in material design, material processing, material evaluation and material usage had been carried out by the institute of development, guarantee and use of aerospace materials. Based on this, the selection demand of aerospace materials in China was analyzed firstly, and then some discrimination was given on the concept among aerospace materials, flight test of aerospace materials, space materials science, and space environmental adaptability of aerospace materials and so on. Furthermore,the concept of aerospace material engineering was put forward, and the correlation of related parts composition of aerospace material engineering is described. Finally, to meet the needs of the future development of space technology, based on the domestic and abroad development of aerospace material engineering experience, the aerospace material engineering system is constructed from planning, development, test (experiment), evaluation, data base, data service, standard and other aspects.
