Abstract
An experimental study was performed to determine the effect of type of tabbing material and tab taper on the measured axial compressive strength of a unidirectional carbon/epoxy material. Two types of tabbing materials (hot-rolled, low carbon steel and glass-fabric/epoxy) and two tab taper geometries (untapered and 30° taper) were utilized. Additionally, the influence of partial tab debonding on the measured compressive strength was determined. A standard IITRI compression test fixture was used. Tapered steel tabs provided consistently higher compressive strengths than tapered glass-fabric/epoxy tabs, or untapered steel or glass-fabric/epoxy tabs. Deliberately introducing regions of tab debonding in untapered glass-fabric/epoxy tabbed specimens resulted in only a small decrease in compressive strength.
