A [0/90] unsymmetric laminate of material AS/3501 graphite/epoxy is cured at 125C. Assume that both plies are equal in thickness (each layer equal to 't' mm) and have the following properties: E =138.0 GPa, E =8.96 GPa ULT =0.30, = GLT =7.10 GPa = -0.30x10-6/, = =28.10x10-6/C Calculate the laminate curvatures when it is cooled to room temperature (25C). Sketch the curved shape of the laminate. Also discuss how the shape would appear if the thickness-to-width ratio is small (i.e., the laminate is thin).
