Creep in high glass content unidirectional and bidirectional GRP laminates

摘要: The paper presents results of experimental investigation on the creep phenomenon in unidirectional and bidirectional E-glass reinforced epoxy resin laminates containing about 80% glass by weight. strain has been measured at room temperature, 75°C, 100°C 150°C for various stress levels. indicate that though elastic behaviour is practically linear different temperatures levels, viscoelastic strongly non-linear. However, this non-linearity can be expressed an exponent-type relation between nett compliance level hence ‘master-curves’ drawn. Further, conclusively mentioned above almost entirely due to fibres contribution negligible.
