ABSTRACT A blind fastener assembly suitable for use in joint assemblies including advanced composite material workpieces. The blind fastener assembly includes a core pin having an enlarged head, an expander having a head and a tapered nose portion and being mounted to the core pin, and a frangible sleeve mounted to the core pin between the enlarged head and the expander. The blind fastener assembly is insertable through aligned holes in the workpieces so that the head of the expander abuts the accessible side of the workpiece. Relative longitudinal movement of the core pin and the expander nut causes the sleeve to expand over the tapered nose and to break into two pieces, one of the two pieces expanding over the other of the two pieces to provide a large bearing surface on the blind side of the workpieces.
