Effect of Residual Thermal Stresses in Curing Process on the Deformation of Flat and Cylindrical Composite Laminates [PDF]

علوم و تکنولوژی پلیمر, 2009
Unsymmetrical composite laminates deform from the flat state in curing process. According to the "lamination theory" the cured shape of unsymmetrical laminates should always be saddle-like, while considering parameters like specimen lengths and cure ...
