Abstract
A spin fastening system includes a first member and an adhesive layer applied to the first member. A second member is positioned in contact with the adhesive layer. At least a portion of the adhesive layer is cured after the second member is positioned in contact with the adhesive layer to render at least the portion of the adhesive layer substantially rigid. At least one spin fastener is inserted successively through each of the second member, the cured portion of the adhesive layer, and the first member.
Claims15
A method for spin fastening components, comprising:
- applying an adhesive layer to a first member;
- positioning a second member in contact with the adhesive layer;
- curing at least a portion of the adhesive layer after the second member is positioned in contact with the adhesive layer to render at least the portion of the adhesive layer substantially rigid, wherein the cured portion of the adhesive layer is less than an entirety of the adhesive layer;
- and
- inserting at least one spin fastener successively through each of the second member, the cured portion of the adhesive layer, and the first member to mechanically join the first member, the adhesive layer and the second member.

- and
- inserting at least one spin fastener successively through each of the second member, the cured portion of the adhesive layer, and the first member to mechanically join the first member, the adhesive layer and the second member, the at least one spin fastener forcing a liquefied first portion of the second member to accumulate proximate to a head of the at least one spin fastener and forcing a liquefied second portion containing material of the adhesive layer and the first member to accumulate proximate to an exposed portion of a shank of the at least one spin fastener, the cured portion of the adhesive layer preventing any of the liquefied first portion or the liquefied second portion from remaining proximate to the adhesive layer.
