초록

본 논문에서는 편향각을 갖는 직물 복합재료 시편을 제작하여 정적 압축실험과 피로실험을 수행하고 그 결과를 비교하였다. 직물구조의 차이에 따른 압축거동을 평가하기 위해 동일한 섬유와 기지로 구성된 일방향 복합재료와 평직 복합재료의 적층순서를 동일하게 조절한 시편을 준비하였다. 정적 압축실험을 통해 편향각을 갖는 시편의 강성과 강도를 측정하였고, 측정된 강도를 바탕으로 압축강도 예측식을 제안하였다. 피로실험을 통해 복합재료의 직물 구조의 차이에 의한 피로수명의 변화를 관찰하였으며, 편향각의 변화와 하중조건에 따른 피로수명의 차이를 비교하였다.

In this paper, static compressive test and compression-compression fatigue test of carbon/epoxy composites which have different micro-structures were carried out with respect to the bias angle. In order to find out the effect of the micro-structure of the fabric composite on compressive characteristics the specimens made of UD carbon/epoxy composite comprising the same fiber and matrix system as the fabric composite were also prepared. The compressive strength and modulus were measured and these values were used to develop a semi-empirical formula for predicting compressive strength of the fabric composite with bias angles. The fatigue behavior of the fabric composite with respect to the bias angle variation was also investigated.
