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.

Claims (25)

1. 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.

2. The method for spin fastening components of claim 1 , further including rotating the at least one spin fastener such that when a penetration end of the spin fastener at least one is brought into direct contact with an outward facing surface of the second member, heat and pressure generated by the penetration end at the outward facing surface causes a portion of a material of the second member to liquefy.

3. The method for spin fastening components of claim 1 , further including:

forcing a first outward flow portion of a liquefied material of the adhesive layer and of the first member to congregate between an outward facing surface of the second member and a head of the at least one spin fastener; and

pushing a second outward flow portion of a liquefied material of the cured portion of the adhesive layer and of the first member outward from the first member to pool in contact with an outward facing surface of the first member, the cured adhesive preventing any of the first outward flow portion or the second outward flow portion from remaining proximate to the adhesive layer.

4. The method for spin fastening components of claim 1 , further including embedding a plurality of spheres into the adhesive layer, each of the spheres having a common diameter substantially equal to a desired thickness of the adhesive layer.

5. 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 a portion of the adhesive layer after the second member is positioned in contact with the adhesive layer to render the cured 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, 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.

6. The method of claim 5 wherein the at least one spin fastener liquefies the liquefied first portion of the second member when the spin fastener at least one is inserted.

7. The method of claim 5 further comprising embedding a plurality of spheres into the adhesive layer.

8. The method of claim 7 , wherein each of the spheres has a common diameter substantially equal to a desired value of a thickness of the adhesive layer.

9. The method of claim 8 , wherein each of the spheres is a polymeric material.

10. The method of claim 8 , wherein when the second member is positioned in contact with the adhesive layer the spheres directly contact a surface of the first member and an oppositely directed surface of the second member.

11. The method of claim 8 , wherein the spheres are substantially incompressible by a force exerted on the adhesive layer during insertion of the at least one spin fastener such that contact of the second member with the adhesive layer does not compress the adhesive layer below a desired thickness of the adhesive layer.

12. The method of claim 8 , wherein when a material of the spheres cannot be liquefied by a temperature generated during insertion of the at least one spin fastener, the spheres are selectively embedded into the adhesive layer outside of a predefined width of the cured portion of the adhesive layer to avoid contact by the at least one spin fastener with the spheres.

13. The method of claim 5 , wherein the adhesive layer is applied in a substantially viscous liquid form to a surface of the first member prior to positioning of the second member.

14. The method of claim 5 , wherein a width and a position of the cured portion of the adhesive layer are predetermined to suit a desired installation location of one of the at least one spin fastener.

15. The method of claim 5 , wherein a thickness of the adhesive layer after curing and prior to installation of the at least one spin fastener is substantially fixed and is not substantially compressible during insertion of the at least one spin fastener.
