초록

본 연구에서는 탄소/페놀 8-매 주자직 복합재료의 기하학적 매개변수를 고려하여 3차원 열적 및 기계적 등가물성치를 예측하였다. 등가탄성계수와 열팽창계수는 일축인장하중과 순수전단, 가상의 온도변화 등을 수치적으로 모사하는 수치실험을 통하여 계산하였다. 8-매주자직 복합재료의 미세구조는 마크로요소를 통하여 모델링 하였고 단위구조해석을 위해 주기경계조건을 유도하였다. 또한 다양한 층간 위상차를 고려하기 위해 모작위 표본 해석을 수행한 후 그 결과에 대하여 통계처리를 수행하였고, 해석결과는 인접층간 위상차와 적층수 및 굴곡도 등의 매개변수가 등가물성치에 미치는 영향의 관점에서 조사되었다. 그리고 시편에 대한 실험을 실시하여 계산결과와 비교하였다.

In this paper, three-dimensional thermo-mechanical properties of carbon-phenolic 8-hamess satin weave composites were predicted considering geometric parameters of microstructures. The effective properties were calculated by a series of numerical experiments based on unit cell analysis. The microstructural details were modeled through macro-elements, and the periodic boundary conditions were derived for corresponding un it cell types. The Monte Carlo method was employed to consider the random phase shift between the layers, and the results were investigated on the effect of the geometric parameters of shift, number of layers and waviness ratios. Experimental tests were also performed and the results were compared.
