Notes:
In the present paper, effects of through-the-thickness stitching of delaminated glass/epoxycomposite laminates with two different types of aramid threads, Kevlar® and Twaron® threads, on thebuckling loads are studied. The buckling loads are predicted based on the Southwell, Vertical displacementand Membrane strain plot methods from the experimental data. Flexural modulus of the stitched andunstitched glass/epoxy composite laminates, knot tensile strength of Kevlar® and Twaron®stitching threads are obtained experimentally. From the Southwell, Vertical displacement andMembrane strain plot methods it is observed that stitching either by Kevlar® or Twaron® threadsis effective in improving the buckling strength of glass/epoxy composite laminates when thedelamination length is greater than 0.5L, L is the length of the laminate
