Abstract

An elongated element can include a first flange and a second flange, where the first flange is joined to the second flange at an apex, and a reinforcement element can be embedded within the elongated element, where the reinforcement element is made from a first material and the elongated element is made from a second material, wherein the first material is different than the second material. A method can include extruding a reinforcement element from a first material, feeding the reinforcement element to an extruder, extruding a body of an elongated element from a second material, where the body comprises a first flange, a second flange, and a first apex, where the first flange is joined to the second flange at the first apex, and where the first material is different than the second material, and embedding the reinforcement element into the body.

First claim

What is claimed is:

1 . An elongated element configured to engage with one or more construction panels, the elongated element comprising:
a body that comprises a first flange, a second flange, and a first apex, wherein the first flange is joined to the second flange at the first apex; and a reinforcement element embedded within the body, wherein the reinforcement element comprises a first material and the body is made from a second material, wherein the first material is different than the second material.

2 . The elongated element of claim 1 , wherein multiple reinforcement elements are embedded in the body.

3 . The elongated element of claim 1 , further comprising at least one of:
wherein the body is formed by extrusion, injection molding, or press molding, wherein the reinforcement element is formed by extrusion, wherein the body and the reinforcement element are extruded together, wherein the body is extruded and forms an extruded body, and the reinforcement element is embedded in the extruded body, wherein the reinforcement element is laid in a mold and the second material is formed around the reinforcement element to embed the reinforcement element in the body, wherein the body is extruded and forms an extruded body, and the reinforcement element is pressed into the extruded body, wherein a diameter of the reinforcement element varies along the reinforcement element, and wherein the body and multiple reinforcement elements are extruded together.

4 . The elongated element of claim 1 , wherein the reinforcement element has a cross-section that is a rectangle, a square, a circle, an oval, a triangle, an hourglass, a diamond, a polygon, a pentagon, a hexagon, a star, a rectangular corner, an ellipsoid, or a trapezoid, and wherein the body has a cross-section that is V-shaped, L-shaped, U-shaped, Z-shaped, W-shaped, Step-shaped, or flat-shaped.

5 . The elongated element of claim 1 , further comprising at least one of:
wherein the first flange is rotatable relative to the second flange within a range of angles from 1 degree to 180 degrees relative to the first apex, wherein the first apex is flexible, and the first flange is rotatable relative to the second flange within a range of angles from 30 degrees to 180 degrees relative to the first apex, wherein the first apex is fixed, and the first flange is rotatable relative to the second flange within a range of angles from 45 degrees to 135 degrees relative to the first apex, wherein the first material has increased strength as compared to the second material, and wherein the reinforcement element is embedded in the body along any one of the first apex, the first flange, or the second flange.

6 . The elongated element of claim 1 , wherein a first laminate is adhered to one side of the elongated element and a second laminate is adhered to an opposite side of the elongated element, and wherein the first laminate or the second laminate comprises paper; paperboard; fiberglass, either oriented such as mesh, or non-oriented; textiles/fabrics either organic, non-organic, or blend; polymer films such as nylon, polyethylene terephthalate PET, polyether ether ketone PEEK, polyethylene PE; fabric; plastic; fiber mat; or combinations thereof.

7 . The elongated element of claim 6 , wherein a first flap is adhered to an opposite side of the elongated element, and wherein the first flap is spaced away from the first apex and extends past an edge of the first flange, wherein a second flap is adhered to an opposite side of the elongated element, and wherein the second flap is spaced away from the first apex and the first flap, and extends past an edge of the second flange, and wherein the first flap or the second flap comprises a paper, a paperboard, a fiberglass, a fabric, a plastic, a fiber mat, or combinations thereof.

8 . The elongated element of claim 1 , wherein an impact damage of the elongated element made from the second material is at least 5% less than an impact damage of a second elongated element that is made from the second material without one or more reinforcement elements being embedded in a second body of the second elongated element, wherein the impact damage is measured per an ASTM standard C1921.

9 . A method for manufacturing an elongated element, the method comprising:
extruding, via a first extruder, a reinforcement element from a first material; feeding the reinforcement element to a second extruder; extruding, via the second extruder, a body of an elongated element from a second material, wherein the body comprises a first flange, a second flange, and a first apex, wherein the first flange is joined to the second flange at the first apex, and wherein the first material is different than the second material; and embedding the reinforcement element into the body.

10 . The method of claim 9 , wherein embedding further comprises embedding the reinforcement element into the body while the body is being extruded.

11 . The method of claim 9 , wherein embedding further comprises embedding the reinforcement element into the body after the body has been extruded.

12 . The method of claim 9 , wherein extruding the reinforcement element further comprises extruding two or more reinforcement elements via one or more first extruders, and wherein embedding the reinforcement element further comprises embedding the two or more reinforcement elements in the body.

13 . The method of claim 12 , wherein the two or more reinforcement elements comprise a first reinforcement element and a second reinforcement element, wherein the first reinforcement element is made from the first material and the second reinforcement element is made from a third material, and wherein the first material is different than the third material.

14 . The method of claim 9 , further comprising embedding the reinforcement element into the body along the first flange, the second flange, the first apex, or any combination thereof as the body is being extruded.

15 . The method of claim 9 , wherein the body has a cross-section that is V-shaped, L-shaped, U-shaped, Z-shaped, W-shaped, Step-shaped, or flat-shaped, and wherein the reinforcement element has a cross-section that is a rectangle, a square, a circle, an oval, a triangle, an hourglass, a diamond, a polygon, a pentagon, a hexagon, a star, a rectangular corner, an ellipsoid, or a trapezoid.

16 . The method of claim 9 , further comprising rotating the second flange relative to the first flange about the first apex to an angle that is within a range from 45 degrees to 180 degrees.

17 . The method of claim 16 , further comprising rotating the second flange relative to the first flange about the first apex to an angle that is within a range from 45 degrees to 135 degrees.

18 . The method of claim 9 , wherein the first material is an extrudable material, and wherein the extrudable material comprises one of tin, zinc, iron, copper, aluminum, steel, thermoplastic polymer, polyvinylchloride (PVC), chlorinated polyvinyl chloride (CVPC), polyethylene (PE), polypropylene (PP), nylon, polystyrene (PS), poly(acrylonitrile-butadiene-styrene) (ABS), poly (acrylic styrene acrylonitrile) (ASA), poly(acrylonitrile ethylene styrene) or poly(acrylonitrile ethylene propylene styrene) (AES), acrylic, polymethylmethacrylate, polycarbonate (PC), poly(methyl methacrylate) (PMMA), polyesters, polysulfones, polyphenylene oxide, PVC composite, PE composite, PP composite, or a combination thereof.

19 . The method of claim 9 , wherein the body further comp
