    Abstract

    A theory for the prediction of creep and microyield strength of composite laminates with visco-elastic matrices has been developed and tested. Precise creep curves from three laminates with arbitrary orientations provide the necessary input data. The time dependent lamina properties are derived for subsequent use with standard laminate codes. Both the level and shape of creep and strain recovery curves can be predicted. Extensions of the theory to include the effects of microcracking are outlined.
