Adhesive encapsulated blind rivet system

A method of blind riveting to join a plurality of parts comprising the steps of:

• a) providing at least two parts with facing surfaces, a surface accessible for rivet insertion, an inaccessible surface, and a combined thickness at a joining place, the parts having aligned holes at the joining place through the combined thickness and facing surfaces;
• b) providing a blind rivet comprising:
• a tubular rivet body comprising a rivet head portion for engaging the accessible surface and a sleeve portion for extending from the rivet head portion past the inaccessible surface, the rivet head portion and sleeve portion including a longitudinal bore formed therein, the sleeve portion having a length and a circumference and a plurality of adhesive outlet holes spaced along the length and around the circumference of the sleeve portion;
• a mandrel including a head portion having a diameter greater than the bore and a shaft portion extending from the head portion, the shaft portion disposed in the bore, and wherein the head portion is disposed proximate the end of the rivet body opposite the rivet head portion;
• an adhesive disposed in an annular space defined by an interior surface of the bore and an exterior surface of the shaft portion;
• c) inserting the tubular rivet body into the aligned holes such that the rivet head portion of the tubular rivet body engages the accessible surface of the plurality of parts;
• d) positioning an installation tool having a seal that intersects with the rivet head portion;
• e) installing the blind rivet wherein the installation tool grips the shaft of the mandrel and draws the mandrel head portion into the bore forming a blind head mechanically attaching the plurality of parts and wherein a pressure is applied to the seal preventing escape of the adhesive such that the adhesive is extruded through the adhesive outlet holes from the annular space to a region between the facing surfaces of the plurality of parts to be joined and to a region between the tubular rivet body and interior surfaces of the aligned holes of the parts to be joined.
