Abstract
New families of hygro-thermally curvature-stable laminates are presented within the framework of a unified approach to laminate design incorporating complex mechanical coupling behaviour, which includes all possible interactions between extension, shearing, bending and twisting. Necessary conditions for hygro-thermally curvature-stable laminates are developed, from which new stacking sequence configurations with standard angle-ply and cross-ply sub-sequences are then derived. All stacking sequence configurations are characterised according to their unique mechanical coupling behaviour, with polar plots used to illustrate the changes in off-axis mechanical coupling behaviour for each laminate family; with respect to extensional, coupling and bending stiffness and the associated lamination parameters. The new stacking sequence configurations are applicable to any orthotropic fibre/matrix system with constant ply thickness throughout and although standard angle-ply and cross-ply combinations are the primary focus of the study, a number of important observations are reported concerning double angle-ply laminates and laminates with non-standard angle-ply orientations.
