Abstract

In order to manufacture and produce the components to be used for developing aerospace products, it is essential to determine the conformity of material characteristics to the design requirements. However, since the Korean industry has no experience to develop aircraft and spacecraft, the national certification system has not been established. Hence, it is necessary to define the qualification methodology of material to establish the durability and the safety of aircraft and spacecraft. In this paper the characterization methodology which has been performed in aeronautically advanced countries for determination of conformity in materials and production process is reviewed. The change of material properties due to the space environment and the example of evaluation program of composites for the application of aircraft are presented. so that the foundation of evaluation system for aerospace materials can be initiated.

현재 계획중인 항공우주상업과 관련된 부품을 제조하여 생산하기 위해서는 사용된 재료가 설계요구조건에 적합한지가 평가되어야 한지만 국내에서는 항공기나 우주비행체를 개발한 경험이 없으므로 평가체제가 확립되어 있지 않다. 따라서 항공기 및 우주비행체의 내구성과 안전성확보에 필요한 재료의 인정방법을 정의할 필요가 있다. 본 기고에서는 항공우주 선진국에서 수행하고 있는 재료 및 가공공정의 합치성 결정에 필요한 특성시험을 고찰하고, 우주환경에 의한 재료특성 변화와 항고기용 복합재료 평가의 예를 제시하여, 국내의 항공우주용 재료 평가체제 확립의 기초가 되도록 하였다.
