15-5-18 : 繊維強化複合材料材料のハイブリッド化による高機能性の発現

Fiber reinforced plastics (FRP) in which two or more kinds of fibers are embedded are called hybrid composites. Most popular hybrids are glass/carbon and Kevlar/carbon hybrids. The main advantages of GFRP we high elongation, low cost, and good impact resistance, while those of CFRP we high strength, high stiffness, low density and good moisture-resistant property. By the addition of carbon fiber to GFRP a hybrid composite with increased stiffness, satisfactory strength, and reasonably low cost will be anticipated. Some synergistic benefits may be possible which are called “hybrid effects”. Although there have been many works on the hybrid effect, little is focused on creep behavior of hybrid composites. In this research, creep tests of GFRP, CFRP and GE/CF intra-hybrid laminates were carried out and the hybrid effect was investigated.Article先進ファイバー工学研究教育拠点研究成果報告書 11: 130-130(2005)research repor
