Abstract:
A method of riveting a first member to a second member, comprising the steps of:(a) providing a piercing rivet having a central axis, a head portion and an annular portion extending outwardly from a bottom surface of the head portion wherein; (i) the annular portion defines a cavity; (ii) at least one passage extends through the annular portion; and (iii) an adhesive in a flowable state is disposed in the cavity of the annular portion; (b) placing the first member on the second member, wherein each of the members has a first side and a second side, and at least a portion of the second side of the first member is in overlapping contact with at least a portion of the first side of the second member for forming an overlapped region; and c) driving the rivet through the first member and at least partially through the second member in the overlapped region wherein; (i) the annular portion of the rivet is deformed radially away from the central axis of rivet to interferingly secure the rivet to the members thereby attaching the members to each other; and (ii) the adhesive is forced out of the cavity of the rivet through the passage of the rivet thereby positioning the adhesive between an outer annular surface of the rivet and portions of the first member and the second member; and (d) curing the adhesive to adhesively secure the rivet to the first and second members.
