Effects of Edge-sealed on Water Absorption of Glass Fiber Reinforced Epoxy Resin Composites
摘要
Abstract
Effects of edge-sealing on water absorption of glass fiber reinforced epoxy resin composites (GF/E-51) were investigated by weight measurement and volume measurement of composites specimen. Hie experimental results show that the difiusivity coefficient of edge absorption is far more than that of die surface absorption and die maximum moisture content of the unsealed specimen increases by 73.8%. Meanwhile, the volume dilatation of the unsealed specimen increases by 200.1%, which indicates that the mechanism of water absorption of GF/E-51 can be classified into two types: open-porous absorption and close-porous absorption. Water behaves as a vapor-phase in the porous close composite, but as a liquid-phase in porous open absorption.关键词
