AN EXPERIMENTAL INVESTIGATION OF THE LARGE DEFLECTION BENDING CHARACTERISTIC FOR THE GLSS FIBER-EPOXY MATRIX MULTIDIRECTIONAL LAMINATES

The bending characteristic of large deflections for the glass fiber-epoxy matrix multidirectional laminates,including the specimen of beams, rectangular and triangular plates under the action of concentrated load at point A are investigated in this paper.The maximum deflections 8 are between 2.5 to 10.0 times of the thickness h of the specimens.The basic behavior and the law revealed from these experiments will be of help to develop a foundational theory and the calculation method for the laminates.
