Warping of Unsymmetric Cross-Ply Graphite/Epoxy Laminates

CODEN: JCTRER

Abstract

Residual stresses in composite laminates are induced by the anisotropic expansional properties of the constituent unidirectional plies. Immediately after fabrication, laminates are subjected to curing stresses because of the thermal expansion mismatch between plies with different fiber orientations. Furthermore, as the laminates are left in a moist environment, they absorb moisture and swell. The swelling strains can offset the curing strains with the net result of reduced residual stresses.
