Experimental buckling loads, lateral second-order deformations, and shear strength decreased with increasing temperature until stable values were reached at a much lower level in the leathery material state. The resin-dominated bending stiffness decreased at a higher rate than the fiber-dominated compressive stiffness. Global buckling followed by a delamination failure during the post-buckling process was observed for temperatures below 180 °C, while pre-buckling kink-band failure occurred when the temperature increased to 220 °C. Recently proposed thermomechanical models were further validated and enabled the changing failure mode and associated Tresca and kink-band shear stress and strength conditions to be modeled. © 2010Glass fibersResinsShear strengthSteel sheetStiffnesstext::journal::journal article::research article
