진공적층법을 이용한 능직 GFRP/CFRP 적층하이브리드 복합재의 층간 ModeⅡ 파괴인성 평가 = Interlayer ModeⅡ Fracture Toughness Evaluation of Twill GFRP/CFRP Laminated Hybrid Composite Material Using Vacuum Lamination Method

다국어 초록 (Multilingual Abstract)

Various composite materials are being used to realize light weight and high strength throughout the industry. Fiber-reinforced composites differ in strength and application range depending on how the fibers are weaved. In addition, defects may occur in the fibers depending on the temperature and pressure of the molding conditions. These defects result in a variety of fracture mechanisms, typically due to interlayer fracture. There has been a lot of research on interlayer fracture of plain CFRP composite materials, but there is a lack of research on GFRP/CFRP laminating hybrid composite of twilled weave structure with excellent resistance to fibrous deformation compared to plain weave. In consideration of this reality, a modeⅡ fracture test was performed by making GFRP and CFRP of twilled structure into 4ENF specimens by applying the molding conditions used in manufacturing products in industrial sites. As a result, the energy release rate and the stress intensity factor tended to decrease as the initial crack length increased.
