Abstract

An assembly for utility truck bodies having metal and/or composite reinforcement(s) and/or foam reinforcements and/or honeycomb reinforcement/and/or wood reinforcements encapsulated within a thermoformed thermoplastic, or thermoset or fiber-reinforced thermoset walking surface floor structure of the truck bed assembly or other composite floor structure with attachable components and junctions, e.g., sidepack(s), and methods of making the same are provided.

First claim

The invention claimed is:

1. A sidepack door comprising:
at least two sheets of thermoplastic per sidepack door including a first sheet of thermoplastic and a second sheet of thermoplastic;
wherein the first sheet of thermoplastic and the second sheet of thermoplastic are arranged in a waterproof sandwich configuration; and
wherein the first sheet of thermoplastic and the second sheet of thermoplastic are separated by a gap and periodically joined at kiss-off locations, thereby increasing the stiffness of the sidepack door.

2. The sidepack door of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are twin sheets of thermoformed thermoplastic formed using twin sheet thermoforming.

3. The sidepack door of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are fiber reinforced thermoplastic.

4. The sidepack door of claim 1 , wherein the first sheet of thermoplastic and/or the second sheet of thermoplastic are filled thermoplastics.

5. The sidepack door of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are formed using injection molding, rotational molding, compression molding, compression molding using unidirectional tape, compression molding using sheet molding compound, compression molding using bulk molding compound, compression molding using thick molding, and/or compression molding using wet molding, gravity fed casting, low pressure casting, high pressure casting, resin transfer molding including light resin transfer molding, 3D printing, extrusion, Digital Light Synthesis (DLS) including Continuous Liquid Infusion Production, vacuum forming, infusion including vacuum infusion, hand layup, infusion, flex molding, lamination, squish molding, chop spray, and/or pultrusion.

6. The sidepack door of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are joined via physical bonding, chemical bonding, mechanical attachment, mechanical interlocking, magnetism, reversible adhesive, irreversible adhesive, welding including plastic welding, infusion, lamination, and/or vacuum attachment.

7. The sidepack door of claim 1 , further comprising a foam core including a thermoplastic foam core, a polyurethane foam core, a syntactic foam core, a polymethacrylimide (PMI) foam core, a Polyethylene Teraphalate (PET) foam core, a cross linked polyvinyl chloride (PVC) foam core, a linear PVC foam core, and/or a polyester foam core, a honeycomb core, a wood core, a balsa core, a glass fabric core including a 3D woven sandwich glass fabric core, a fiberglass core, a fabric core including laminate bulkers, and/or a carbon core.

8. The sidepack door of claim 1 , wherein the gap is fully encapsulated by the first sheet of thermoplastic and the second sheet of thermoplastic.

9. The sidepack door of claim 1 , wherein the gap is at least about half the thickness of the first sheet of thermoplastic or the second sheet of thermoplastic.

10. A sidepack door comprising:
at least two thermoset panels per sidepack door, including a first thermoset panel and a second thermoset panel;
wherein the first thermoset panel and the second thermoset panel are arranged in a waterproof sandwich configuration;
wherein the first thermoset panel and the second thermoset panel are separated by a gap and periodically joined at kiss-off locations, thereby increasing the stiffness of the sidepack door; and
wherein the gap constitutes space between the at least two thermoset panels other than where the at least two thermostat panels are joined at the kiss-off locations.

11. The sidepack door of claim 10 , wherein the at least two thermoset panels are manufactured via resin transfer molding, light resin transfer molding, compression molding, compression molding using sheet molding compound, compression molding using bulk molding compound, vacuum infusion, chop spray, pultrusion, injection molding, rotational molding, or hand layup.

12. The sidepack door of claim 10 , wherein the at least two thermoset panels are fiber reinforced thermoset panels.

13. The sidepack door of claim 10 , wherein the at least two thermoset panels are filled thermoset panels.

14. The sidepack door of claim 10 , further comprising at least one thermoplastic material.

15. The sidepack door of claim 14 , wherein the at least one thermoplastic material includes fiber reinforced thermoplastic material.

16. The sidepack door of claim 14 , wherein the at least one thermoplastic material includes a filled thermoplastic.

17. The sidepack door of claim 10 , wherein the at least two thermoset panels are joined via physical bonding, chemical bonding, mechanical attachment, mechanical interlocking, magnetism, reversible adhesive, irreversible adhesive, welding including plastic welding, and/or vacuum attachment.

18. The sidepack door of claim 10 , further comprising a honeycomb core, a wood core, a balsa core, a glass fabric core including a 3D woven sandwich glass fabric core, a fiberglass core, a fabric core including laminate bulkers, a carbon core, and/or a foam core including a thermoplastic foam core, a polyurethane foam core, a syntactic foam core, a polymethacrylimide (PMI) foam core, a Polyethylene Teraphalate (PET) foam core, a cross linked polyvinyl chloride (PVC) foam core, a linear PVC foam core, and/or a polyester foam core.

19. The sidepack door of claim 10 , wherein the gap is fully encapsulated by the first thermoset panel and the second thermoset panel.

20. The sidepack door of claim 10 , wherein the gap is at least about half the thickness of the first thermoset panel or the second thermoset panel.

21. A sidepack door comprising:
at least one thermoset panel and at least one thermoplastic panel in each sidepack door;
wherein the at least one thermoset panel and the at least one thermoplastic panel are arranged in a waterproof sandwich configuration; and
wherein the at least one thermoset panel and the at least one thermoplastic panel are separated by a gap and periodically joined at kiss-off locations, thereby increasing the stiffness of the sidepack door.

22. The sidepack door of claim 21 , wherein the at least one thermoplastic panel includes a fiber reinforced thermoplastic panel.

23. The sidepack door of claim 21 , wherein the at least one thermoset panel includes a fiber reinforced thermoset panel.

24. The sidepack door of claim 21 , wherein the at least one thermoplastic panel and/or the at least one thermoset panel is filled.

25. The sidepack door of claim 21 , wherein the at least one thermoplastic panel is formed using injection molding, rotational molding, compression molding, compression molding using unidirectional tape, compression molding using sheet molding compound, compression molding using bulk molding compound, compression molding using thick molding, and/or compression molding using wet molding, gravity fed casting, low pressure casting, high pressure casting, resin transfer molding including light resin transfer molding, 3D printing, extrusion, Digital Light Synthesis (DLS) including Continuous Liquid Infusion Production, vacuum forming, infusion including vacuum infusion, hand layup, infusion, flex molding, lamination, squish molding, chop spray, and/or pultrusion.
