초록

최근 모든 산업분야에서 기존 소재의 물성을 뛰어넘는 우수한 기계적 특성과 기능적 특성을 만족하는 새로운 소재에 대한 필요성이 점점 증가하고 있으며, 특히 연료 절감과 이산화탄소($CO_2$)와 같은 온난화 가스 배출의 절감을 통한 환경보호가 요구됨에 따라 우주항공 산업에서는 신규 소재를 통한 구조체 경량화에 대한 중요성이 더욱 강조되고 있다. 또한, 신규 소재의 다양한 응용을 위하여 우수한 기계적 물성뿐만 아니라 여러가지 특성에 부합되는 고기능성 맞춤형 재료의 개발은 현재의 재료 과학기술의 최우선적인 목표이며, 이러한 맞춤형 재료에 가장 근접한 소재는 탄소섬 유강화 복합재료라 할 수 있다. 실제로 최근 탄소섬유강화 복합재료는 항공기 경량화를 위한 필수적인 물질로서 그 수요는 크게 증가하고 있다. 따라서, 본고에서는 항공기의 경량화를 위한 탄소섬유강화 복합재료의 필요성과 더불어 탄소섬유강화 복합재료의 기술동향에 대하여 중심으로 살펴보도록 하겠다.

Recently, the need of new materials which have excellent physical properties and functional characteristics has been increased in all industries. In particular, body weight reduction via new materials in aerospace industry was significantly emphasized by the requirement of environmental protection through the fuel savings and reduction of greenhouse gas, i.e., carbon dioxide($CO_2$). Also, for various applications, the development of high performance custom materials with excellent physical properties was the current primary goal of materials science and technology. In this respect, carbon fiber-reinforced composites were the most candidates among the various materials. Indeed, carbon fiber-reinforced composites have been lately used as essential materials for the weight reduction of aircraft and the demand has increased remarkably. Therefore, in this paper, we focused on the need of carbon fiber composites in the fields of aircraft and technique status.
