The present invention relates generally to the reclaiming of carpet waste material. More particularly, the invention relates to a method and system for reclaiming carpet components such as yarn, tufting primary, binder, and secondary backing from post-industrial and post-consumer carpet waste in a substantially continuous flow process.

A method of making products with a functional relief surface (2) with high resolution up to 10 nm, which is copied from a template (1) or carrier of the negative relief of the surface, the so-called master. The template (1) of the relief surface (2) is provided with at least one layer of geopolymer composite, applied in a precursor state (3), in form of a liquid dispersion or grout in plastic or thixotropic condition, whose thickness is the same or greater than the depth of the template relief (1), at temperatures in the interval from the temperature corresponding to properties of the precursor (3) to the temperature corresponding to thermal decomposition of the precursor (3), and after hardening of geopolymer composite the layer or layers is/are separated from the template (1).

A composite core material and methods for making same are disclosed herein. The composite core material comprises mineral filler discontinuous portions disposed in a continuous encapsulating resin. Further, the method for forming a composite core material comprises the steps of forming a mixture comprising mineral filler, an encapsulating prepolymer, and a polymerization catalyst; disposing the mixture onto a moving belt; and polymerizing said encapsulating prepolymer to form a composite core material comprising mineral filler discontinuous portions disposed in a continuous encapsulating resin.

The present disclosure relates to composites. One composite may include a resin and oxidized polyacrylonitrile fibers. The oxidized polyacrylonitrile fibers may be provided as a nonwoven fabric. An additional composite may include a resin and material scraps respectively including carbon fibers. The material scraps may be positioned to at least partially overlap one another and define a substantially continuous layer. The material scraps may be provided as a fabric and/or a plurality of loose fibers.

Provided is a method for producing a decorated cycloolefin resin molded article, the method comprising curing a gel coat composition and polymerizing a cycloolefin polymerizable composition containing a radical generator while the gel coat composition is in contact with the cycloolefin polymerizable composition, thereby containing a decorated cycloolefin resin molded article including a gel coat and a cycloolefin resin layer adhering to each other.

A method of manufacturing a composite product includes recovering a wet composite waste from at least one of the manufacturing process or an end-of-life product. The wet composite waste includes a first resin and a plurality of first fibers that are bound together with the first resin. The method also includes grinding the wet composite waste after recovering the wet composite waste. The method also includes mixing the wet composite waste with the second resin into a homogeneous mixture and placing the homogeneous mixture into a cavity. The method includes curing the second resin of the homogeneous mixture such that the homogenous mixture hardens to form a composite product that includes the first resin, the second resin, and the plurality of first fibers.

A manufacturing method for manufacturing a welded thermoplastic composite and honeycomb core structure is provided. A thermoplastic composite and honeycomb structure is generated by positioning a first thermoplastic composite skin on a support structure, positioning a first thermoplastic film over the first thermoplastic composite skin, positioning a honeycomb core over the first thermoplastic film, positioning a second thermoplastic film is positioned over the honeycomb core, and positioning a second thermoplastic composite skin over the second thermoplastic film. The second thermoplastic composite skin is ultrasonically welded to the honeycomb core. The thermoplastic composite and honeycomb structure is then flipped over, and the first thermoplastic composite skin is then ultrasonically welded to the honeycomb core.
