비대칭 복합적층판의 Warping 해석

The warping of unsymmetric laminated composites is induced by residual curing stress at the room temperature. Classical lamination theory(C.L.T.) predicts the room temperature shapes of all unsymmetric laminates to by a salle. Experimental observations, however, indicate some unsymmetric laminated composites have cylundrical room temperature shapes. This anomalous behavior is explained by the extention of C.L.T. which involves Von Karmans large deflection theory. It is shown that, depending on the thickness, width, length, curing temperature and room temperature of the laminate, critical boundares of the shape change are determined. Theoretical predictions are compared with experimental results of Toray Graphite/Epoxy [0n/90n]t.
