Method of forming fastenable member for sealing, baffling or reinforcing
View Patent ↗There is disclosed a member for sealing, baffling and/or reinforcing components of an automotive vehicle. The assembly generally includes a carrier, an expandable material and at least one fastener.
1. A method comprising:
providing a carrier having a base and one or more carrier extensions extending away from the base;
disposing an expandable material upon the carrier material in a continuous manner;
providing a fastener connected to the carrier, wherein the fastener:
i. is integrally formed with the carrier;
ii. includes a first pair contoured fastener extensions; and
iii. a second pair of fastener extensions.
2. A method as in claim 1 wherein the carrier is provided as a strip or film of material and the expandable is disposed upon the carrier by extrusion.
3. A method as in claim 1 wherein the expandable material is disposed upon the carrier by cross-head extrusion.
4. A method as in claim 1 wherein the carrier is provided by extrusion and the carrier is extruded simultaneously with the expandable material, the carrier is extruded prior to the coextrusion of the expandable material upon the carrier or the carrier is coextruded with the expandable material and the resulting coextrusion is further extruded to form a profile configuration.
5. A method as in claim 1 wherein the expandable material is adapted for forming a sealing material, an acoustical material, an adhesive, a structural foam, or a combination of at least two of the foregoing.
6. A method as in claim 1 wherein the carrier further includes a layer of a material over at least a portion of its surface that is applied thereto by coextrusion, lamination, adhesion, vapor deposition, plasma deposition, spray coating, brushing, swabbing, dipping, plating or combinations thereof.
7. A method as in claim 1 wherein the expandable material is a material that is thermally deformable at the temperature of extrusion, but upon thermal activation at an elevated temperature will cross link to form a thermoset material.
8. A method as in claim 1 wherein the expandable material includes a plastic selected from the group consisting of thermoplastics, thermosets, or a combination thereof or a resin selected from the group consisting of an epoxy resin, a thermoplastic resin, an acetate resin, an EPDM resin, a phenoxy resin, a polyurethane resin or a combination thereof.
9. A method as in claim 1 wherein the carrier is formed at least partially of a material selected from a metal, a polymeric material, a carbon fiber, graphite, glass, or combinations thereof.
10. A method as in claim 1 wherein the carrier is formed from a polymeric material that is selected from a polyolefin, a polyamide, a polyester, polystyrene, a poly(meth)acrylate, a polyvinyl chloride, a polysulfone, or combinations thereof.
11. A method as in claim 1 wherein the carrier is formed of a polymeric material selected from polyethylene terephthalate, high density polyethylene, polyvinyl chloride, low density polyethylene, polypropylene, polystyrene, or combinations thereof.
12. A method as in claim 1 wherein the carrier is formed of a polymeric material that is selected from a polycrystalline material, an amorphous material or a combination thereof.
13. A method as in claim 1 wherein the carrier is formed of a polymeric material that is paintable to result in a class A automotive vehicle surface finish.
14. A method as in claim 1 wherein the length of the carrier along its longitudinal axis is smaller than the height of the carrier.
15. A method as in claim 1 wherein, prior to expansion of the expandable material, at least about 10% of the outer surface area of the carrier is covered with the expandable material.
16. A method as in claim 1 wherein at least one end portion of the carrier is embedded in the expandable material.
17. A method as in claim 1 wherein the expandable material has a configuration that is contoured.
18. A method as in claim 1 , wherein the second pair of fastener extensions are shaped as an arrowhead fastener.
19. A method as in claim 1 . including locating the carrier within an opening in a cavity wall so that the first pair of fastener extensions abut an inner surface of the cavity wall.
20. A method as in claim 1 , including locating the carrier within an opening in a cavity wall so that the second pair of fastener extensions abut an outer surface of the cavity wall.
