Abstract
A fastener assembly is inserted into a throughhole of a composite laminate to thereby fasten the composite laminate together. The throughhole has a length extending from a first outer surface of the composite laminate to a second outer surface of the composite laminate. The throughhole has a first width at the first outer surface, a second width at the second outer surface, and a third width at a point along the length of the throughhole between the first outer surface and the second outer surface. The third width is less than each of the first width and the second width. The fastener assembly includes a substantially annular fastener device having an axial opening and a peripheral surface substantially conforming to the inner surface of the throughhole. An elongate element is tightly received within the axial opening of the fastener device and biases the peripheral surface of the fastener device against the inner surface of the throughhole such that both the fastener device and the elongate element are substantially entirely disposed between the first outer surface and the second outer surface of the composite laminate.
