초록

부직포를 이용한 하이브리드 복합재료는 일반적인 섬유강화 적층복합재료의 기계적 특성을 개선하기 위하여 개발되었다. 부직포 하이브리드 프리프레그는 전형적 FRP 프리프레그와 부직포 프리프레그로 이루어전 있다. 부직포 프리프레그는 부직포와 수지의 조합에 의해 만들어진다. 부직포는 단섬유가 평면상에 불규칙적으로 분산되어 배치된 형상이다. 부직포를 이용한 하이브리드 프리프레그의 개발목적은 (i) 적층간의 층간특성(층간파괴인성 및 층간강도)을 향상시키고, (ii) 저비용으로 재료의 기계적 강도에 대한 신뢰성을 개선하며, (iii) 복합적층판에서 강화가 요구되는 층에 인성과 강도를 부여함에 있다. 상기의 목적을 달성하기 위하여 부직포층의 기포를 감소시키기 위한 제조기술을 제안하였다. 그 결과, 부직포를 이용한 하이브리드 개념을 도입함으로써 복합적층판의 층간파손특성이 크게 개선되었다.

The hybrid composite materials with non-woven tissue (NWT) was developed to improve the mechanical properties of conventional FRP composite materials. The hybrid prepreg with NWT consists of FRP prepreg and NWT prepreg. The NWT prepreg consists of NWT and polymer resin. The NWT has short fibers, discretely distributed with in-plane random orientation fibers. The purposes of this study of hybrid prepreg with NWT are (i) to increase the interlaminar properties(the fracture toughness and strength), (ii) to improve the mechanical properties and reliability, while maintaining a low cost, (iii) to introduce a tough and strong interlayer at critical positions to be required of strength in the laminate. To accomplish the above purposes, a production technique to decrease voids in NWT layers was proposed in this paper. The interlaminar failure characteristics of laminated composite materials was tremendously improved by hybrid concept with NWT.
