20080213562 | Plastic Composites Using Recycled Carpet Waste and Systems and Methods of Recycling Carpet Waste - An extruded composite utilized as a building material includes a base polymer, unseparated processed recycled carpet waste, and a filler material, which may be a wood filler or other natural fiber. Carpet waste may be separated into components that may be utilized in a variety of plastics applications, including extruded composites utilized as building materials. Separation may include shaving face fiber from bound fiber secured in a backing fiber and/or may include separating fiber pile and backing fibers from carpet adhesive to remove inorganic materials such as calcium carbonate. | 09-04-2008 |
20100159213 | Wood-Plastic Composites Utilizing Ionomer Capstocks and Methods of Manufacture - An extruded composite adapted for use as a building material includes a core having a base polymer and a natural fiber in a substantially homogeneous mixture and an ionomer capstock. To improve adherence of the ionomer to a base polymer, the ionomer can be mixed with a similar or substantially similar base polymer prior to coextrusion with the core. Additionally, various additives may be mixed with the capstock material to improve visual aesthetics of the product and performance of the building material, especially over time. | 06-24-2010 |
20110073824 | RAILING SYSTEM AND COUPLING ELEMENT AND METHODS OF ASSEMBLY - A connector for attaching a hollow baluster to a hollow rail in an extruded railing system includes two sections. A plug portion is adapted to be received in an end of the hollow baluster. A projection is adapted to be received in an aperture formed through a wall of the hollow rail. The projection may include a resilient tab configured to engage an interior surface of the hollow rail when received therein. In one embodiment, the plug portion and projection have axes that are not collinear and form an included angle. An outer taper of the plug portion allows for installation in stairway railing systems having ramp angles that deviate from the nominal. | 03-31-2011 |
20110097552 | CARPET WASTE COMPOSITE - A composite material produced from carpet waste and a binding agent, in intimate association, which material includes 25% and 99% carpet waste and between 1 and 25% binding agent. A method for manufacturing the composite material is also disclosed. | 04-28-2011 |
20110229691 | Carpet Waste Composite - A composite material is produced from carpet waste and a binding agent, in intimate association, and may also include wood fiber or chips and/or other additives. A method of manufacturing a composite material includes shredding carpet waste, coating the carpet waste with a binding agent, and subjecting the shredded, coated carpet waste to elevated heat and pressure. As an additional step, the composite material may be actively cooled to prevent deformation of the material. | 09-22-2011 |
20120077890 | Composite Building Materials and Methods of Manufacture - A composite building material includes carpet waste having carpet fibers and adhesive, and an inorganic filler that includes fly ash. The composite building material may be produced by providing the carpet waste, mixing the carpet waste with the inorganic filler to produce a homogeneous blend, and forming the homogeneous blend into the composite building material. The composite building material may optionally include a base polymer, slack wax, and/or calcium carbonate. | 03-29-2012 |
20120315471 | Composites Utilizing Polymeric Capstocks and Methods of Manufacture - An extruded composite adapted for use as a building material includes a core having a base polymer and a filler material in a substantially homogeneous mixture and a polymeric capstock modified with an elastomer and/or a plastomer. To improve adherence of the polymeric capstock to the base polymer, the capstock can include a capstock polymer that is similar or substantially similar the base polymer. Additionally, various additives may be mixed with the capstock material to improve visual aesthetics of the product and performance of the building material, especially over time. | 12-13-2012 |
20130102707 | CARPET WASTE COMPOSITE - A composite material is produced from carpet waste and a binding agent, in intimate association, and may also include wood fiber or chips and/or other additives. A method of manufacturing a composite material includes shredding carpet waste, coating the carpet waste with a binding agent, and subjecting the shredded, coated carpet waste to elevated heat and pressure. As an additional step, the composite material may be actively cooled to prevent deformation of the material. | 04-25-2013 |
20150024171 | Carpet Waste Composite - A composite material is produced from carpet waste and a binding agent, in intimate association, and may also include wood fiber or chips and/or other additives. A method of manufacturing a composite material includes shredding carpet waste, coating the carpet waste with a binding agent, and subjecting the shredded, coated carpet waste to elevated heat and pressure. As an additional step, the composite material may be actively cooled to prevent deformation of the material. | 01-22-2015 |
20150044434 | Systems and Methods for Generating Surface Patterns on Composite Building Materials - Systems and methods are described for generating surface patterns on composite building materials. An example method includes: providing a base polymer; providing a natural fiber; mixing and heating the base polymer and the natural fiber to produce a base mixture including a substantially homogeneous melt blend; extruding the blend through a die to form an extruded profile; and dispensing a pigment from a micro-extruder onto a surface of the extruded profile to form a colored surface pattern. | 02-12-2015 |
