A body of extruded polymer fibers formed and welded together in a three-dimensional shape with a fastener comprising a stake inserted into the body. The stake comprises a head that secures the fastener to the body. The body comprises extruded polymer filaments randomly oriented and bonded together to form a three-dimensional mesh structure. The polymer stake extends from a plate through a first side toward a second side of the body to a location on the surface of the body or a location within the body. A portion of the filaments is disposed between the first side of the body and the head. A method of attaching the fastener to the body comprises inserting the stake, forming the head, and attaching the head to the body.

A method of joining multiple components is disclosed. The method includes arranging a first component having a first surface, an opposing second surface, and a feature, in contact with a second component having a first surface, an opposing second surface, and defining an aperture. When so arranged, the first surface of the first component is adjacent to the second surface of the second component. The method also includes positioning a fastener on the first surface of the second component and in contact with the feature of the first component, such that at least a portion of the fastener overlaps the aperture on the first surface of the second component. The method additionally includes abutting and fusing the fastener to the feature of the first component to thereby affix the first component to the second component.

Methods, systems and apparatuses are disclosed for joining assemblies, particularly joints and joining assemblies for co-joining composite components and metal components in a joining assembly, and inhibiting corrosion of metal components secured to composite component via a joining assembly.

A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

Apparatus configured to enable the staking of an interfacing part to a base is provided. The apparatus includes a retainer configured to convey a stake and the interfacing part to the base. The apparatus is further configured to provide a heat and/or vibration to effect the simultaneous attachment of the stake to the base and the interfacing part to the base.
