수분환경에서 열화시 간헐적 건초가 유리섬유 강화 복합재료의 기계적 성질에 미치는 영향 = Effect of Degradation in Aqueous Environment and intermittent Drying on the Mechanical Properties of E-Glass Fiber Reinforced Composites

다국어 초록 (Multilingual Abstract)

The moisture absorption has influence on the mechanical properties of fiber reinforced composites. In this study, we investigate th effect of degradation in various aqueous environment and intermittent drying on the mechanical properties of E-glass fiber reinforced composites. The tensile strength is measured using strand specimen with 40~50wt. % E-glass fiber content and the fracture surfaces are also observed by scanning electron microscope(SEM). The results show that the decreasing tendency of tensile strength as a function of immersion and drying time are similar to the behavior of samples immersed in aqueous environment.
