An experimental and finite-element analysis was performed on graphite/epoxy cloth plates subjected to static shear loading. Two specimens were tested to failure for each of three configurations: a solid panel, a panel with an unreinforced hole and a panel with a 45°-flanged hole. Both a static nonlinear analysis and a bifurcation-buckling analysis were performed for each of the panel configurations. The 45°-flange reinforcement technique for cutouts in shear webs was found to be well-suited for use in non-buckling, graphite/epoxy cloth designs. However, an alternate hole-reinforcement technique is required for designs where buckling is allowed.
