A rivet having improved formability is provided. The rivet has a shank having a head at one end. The shank and the head have a refined grain structure. The rivet is manufactured from the region of the workpiece having a refined grain structure by first forming a region having a refined grain structure in a workpiece and then forming the rivet. The refined grain structure results in improved mechanical properties, such as formability, strength, toughness, ductility, corrosion resistance, and fatigue resistance. The improved formability of the rivet reduces the formation and propagation of cracks during the manufacture and installation of the rivets.

The invention provides a rivetless nut plate including a nut, a holding bracket having tubular and bracket portions, and a stem having an enlarged head. The stem is positioned within an aperture of the tubular portion such that the head is resting on a shoulder within the bracket aperture. The tubular portion is positioned within an aperture of a workpiece, such that the bracket portion rests on top of the workpiece. The nut is retained within the bracket portion. Force is applied to a bottom of the workpiece and another opposite force is applied to the stem such that the head expands the tubular portion radially outwardly such that lobes on the tubular portion become embedded into the wall of the workpiece, thereby securing the nut plate to the workpiece. The holding bracket could also be formed of two separate elements, a sleeve having a tubular portion and a bracket.

A rivetless nut plate has a nut, a holding bracket, a member and a nut retainer. The nut is provided with an aperture therethrough and is secured within a bracket portion of the holding bracket by the retainer but also is permitted limited movement within the bracket portion. The holding bracket further includes a tubular portion having inner and outer walls. The inner wall is tapered such that the member is positioned against the inner wall. Upon an axial force being applied to the member through the aperture of the nut, the member is pushed through the tubular portion from the first end to the second end in order to expand the inner wall and force the outer wall into engagement with the wall of the workpiece. A tool is provided to push the member through the tubular member and can be incorporated into either a manual or automatic process.

A method of securing a nut plate to a workpiece includes the step of providing a nut plate include a nut, a holding bracket having tubular and bracket portions, and a stem. The tubular portion has an aperture therethrough which is inwardly tapered from a first end to a second end thereof. The stem is positioned within the aperture of the tubular portion. The tubular portion is positioned within an aperture defining a wall of a workpiece, such that the bracket portion rests on top of the workpiece. The nut is retained within the bracket portion. A force is applied to the stem such that the head expands the tubular portion radially outwardly from the first end to the second end such that the tubular portion becomes secured to the wall. The holding bracket may be formed of two separate elements, a sleeve having a tubular portion and a bracket.

A rivetless nut plate assembly, which is fully preassembled, which can be installed into an aperture of a composite material workpiece, such as a carbon fiber structure, without risking delamination of the workpiece. The rivetless nut plate assembly includes a nut, a holding bracket, a retainer, and a sleeve member. Additionally, a stem is used to install the rivetless nut plate assembly. The sleeve member is configured such that the nut plate assembly can be installed in a composite material workpiece without risking delamination. The sleeve member may be formed of 45Cb-55Ti Titanium Columbium, as Titanium Columbium is a high strength and ductile material that resists corrosion in the presence of, for example, a carbon fiber composite structure. Monel, Titanium alloys, and other soft Nickel alloys are also good material selections for the sleeve, for similar reasons. Non-metallic materials with high tensile and shear strengths, such as Torlon or Parmax, would provide the desired corrosion protection and also offer a potential weight savings.
