초록

본 연구에서는 수직섬유의 길이가 서로 다른 삼차원 유리직물을 보강재로 사용하고, 매트릭스 수지로 비스페놀 타입 비닐 에스테르 (bisphenol type vinyl ester)를 사용하여 hand lay-up을 이용해 복합재료 (3D composites)를 제조하였다. 삼차원 유리직물의 수직섬유의 길이가 복합재료의 기계적 물성에 미치는 영향을 three-point bending test, flatwise compression test를 통해 조사하였다. Short-beam test법 통하여 복합재료에서의 섬유와 매트릭스 수지간의 계면접착강도를 나타내는 층간 전단강도를 구하였다. 시험 결과를 통하여 수직섬유의 길이가 복합재료의 기계적 물성 및 층간 전단강도에 많은 영향을 미침을 알 수 있었다.

In this work, bisphenol type vinyl ester was impregnated into the three-dimensional glass fabrics fabricated from different thickness changes. Their mechanical properties of the specimens have been investigated by three-point bending and flatwise compression tests. Also, interlaminar shear strength (ILSS) has been determined through short-beam test for the evaluation of interfacial adhesion at interfaces between fibers and matrix of the composites. The effect of thickness changes in three-dimensional glass fabric-reinforced composites have been described in this work.
