摘要:
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.

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.

摘要:
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.

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.

This invention relates to methods and systems for forming composite extrudates including at least a base polymer, a plurality of fibers dispersed in the base polymer, and one or more colorants forming a visible, multi-color pattern, e.g., mimicking the appearance of natural wood.
摘要:
A natural fiber/polymer composite product that includes a core (preferably with a textured surface) and a film or pigment surface layer applied to that textured core surface. The core comprises at least one natural fiber and at least one polymer intimately admixed together to form a composite.
