A method for manufacturing a floor covering product comprises at least a first step of forming a single- or multi-layered substrate by consolidating synthetic material-based starting material. The method comprises a second step after the first step, which is performed in line with the first step. The at least one continuous film is laminated onto the substrate, and the laminating is performed by means of a belt press.

The invention relates to compositions comprising composite materials comprised of discontinuous fibers and one or more polymers and/or oligomers. The invention relates to methods of making the same. The composite materials can be in the form of compositions, composite sheets, laminates, pellets, and/or shaped composite products.

A composite material structure, including an outer layer, an inner layer, and a middle layer, is provided. The outer layer includes a metallic material. The inner layer includes a fiber material and a resin material. The outer layer has a first thickness, the inner layer has a second thickness, and the first thickness is different from the second thickness. The middle layer includes an adhesive material and is disposed between the outer layer and the inner layer. Two opposite surfaces of the middle layer are respectively in direct contact with the outer layer and the inner layer. A manufacturing method of the composite material structure is also provided.

A manufactured composite comprising synthetic turf and impermeable geomembrane is used in a single-layer capping system as the single layer to provide permanent, impermeable and functional aesthetic cover for a job site. During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for a job site.

A method to prepare a composite laminate object containing an extrusion grade 7xxx Al substrate and a fiber-reinforced polypropylene layer adhesively laminated to the substrate; is provided. The process includes shaping and cutting an extruded 7xxx aluminum to a profile, assembling a layered arrangement of the 7xxx Al profile as substrate, an adhesive film and a fiber reinforced polypropylene preform, heating the layered arrangement to a temperature of 160-175 C. to melt the polypropylene and activate the adhesive film, applying pressure to at least a surface of the fiber reinforced polypropylene preform to mold the preform to the shape of the extruded 7xxxAl substrate and obtain a semi-finished laminate object, cooling the semi-finished laminate object to 90 C., optionally, cooling the semi-finished laminate object to room temperature for inventory storage; heat treating the semi-finished laminate object at 90 C. for 2 to 8 hours; and then heat treating the semi-finished laminate object at 130 C. to 150 C. for 8 to 16 hours; and cooling the heat treated object to obtain the composite laminate object.

A panel including at least a substrate of thermoplastic material and a top layer with a printed decor and a translucent or transparent wear layer. The substrate has a thickness larger than one half of the thickness of the entire panel, and the substrate at least includes two layers, where the two layers each include thermoplastic material. A first one of the two layers further includes at least 60 percent by weight of filler materials and a second one of the two layers includes less fillers or is not filled, and is situated above the first one of the two layers.

An improved cover board product with a panel comprised of three discrete layers: a top surface layer comprised of either paper or a fiberglass web, a bottom surface layer comprised of either paper or a fiberglass web, and a core layer comprised of discrete paper fragments and polypropylene fragments, which are connected by use of a thermoplastic bonding resin, including polyethylene. The bonding resin is generally attached in a random pattern to less than 100% of the paper fragment and polypropylene fragment surface area. The paper fragments are generally shaped as irregular plates. The polypropylene fragments can have multiple shape types. The two different fragment types are randomly distributed in the core layer relative to each other. The core layer includes small voids in and around the particles, which improves flexibility. The core layer is attached to the top and bottom surface layers by use of a thermoplastic adhesive, including polyethylene.

An object is to provide a composite material manufacturing method for improving interlayer strength. The present disclosure provides a composite material manufacturing method of laminating a plurality of prepregs (10) formed of a fiber reinforced base material impregnated with an uncured matrix resin and performing hot molding, the method including: using the prepregs (10) each provided with a gap layer (12) that does not contain a resin and is continuous in an in-plane direction and resin layers (11a, 11b) disposed on both surfaces of the gap layer; disposing a plurality of short fibers (13) on facing surfaces of the prepregs (10) that are adjacent to each other; and evacuating the laminated prepregs (10) to degas the gap layer (12) and then performing hot molding.
