Abstract

Composite materials used in aircraft must be certified using approved materials to ensure the the airworthiness of the aircraft. Certification is carried out by verifying the physical properties and processes of the materials, and producing material and process specifications. The composite material certification system in ROK(Republic of Korea) has been established through the MOLIT(Ministry of Land, Infrastructure and Transport) pilot certification project for aircraft composite materials. Currently, the KIAST(Korea Institute of Aviation Safety Technology) operates and manages the certification and shared data system. This study identifies realm for improvement in the established certification system for aircraft composite materials based on empirical evidence and aims to propose measures for the certification and industrial promotion of domestically produced aircraft composite materials


항공기에 사용되는 복합소재는 항공기의 감항성 확보를 위하여 인증된 소재를 사용해야 하며 소재의 물리적 특성 및 공정을 확인하여 재료규격 및 공정규격서등의 인증 문서와 시스템을 승인하는 방식으로 인증이 진행된다. 국내 복합소재 인증시스템은 국토교통부의 항공기용 복합재료 시범인증 사업을 통해 마련되었으며 현재 항공기 전문검사기관인 항공안전기술원에서 인증 및 공유 데이터시스템을 구축하여 운영하고 있다. 본 논문은 실증을 바탕으로 구축된 항공기용 복합소재 인증체계의 개선사항을 식별하고 이에 대한 개선 방안 도출을 통해 국산 항공기용 복합소재의 인증 및 산업 활성화 방안을 제시하였다
