In aeroelastic tailoring or aeroelastic control, the bending-torsional coupling effect for a composite wing has been utilized. As a fundamental study on aeroelastic tailoring, this paper examines the vibration characteristics of cantilevered laminated plates with bending-torsional coupling using lamination parameters which can express every laminate configuration. Effects of laminate configurations and bending-torsional coupling on vibration characteristics are studied through the representation of natural frequencies on a lamination parameter plane. Effects of sweep angle on natural frequencies and associated mode shapes are also discussed for a composite wing model.
