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.
Claims20
A spin fastening system, comprising:
- a first member;
- an adhesive layer applied to the first member;
- a second member positioned in contact with the adhesive layer;
- at least a portion of the adhesive layer being 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;
- and
- at least one spin fastener inserted successively through each of the second member, the cured portion of the adhesive layer, and the first member.
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;
- 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.
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 the adhesive layer after the second member is positioned in contact with the adhesive layer to render the adhesive layer substantially rigid;
- and
- inserting at least one spin fastener successively through each of the second member, the cured adhesive layer, and the first member to mechanically join the first member, the adhesive layer and the second member, the spin fastener forcing a liquefied portion of the second member to accumulate proximate to a head of the 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 spin fastener, the cured adhesive preventing any of the liquefied first portion or the liquefied second portion from remaining proximate to the adhesive layer.
