The forming mould has a forming surface defining said product shape, The method comprises the steps of: arranging a cellulose blank containing less than 45 weight percent water in said forming mould; heating said cellulose blank to a forming temperature in the range of 100° C. to 200° C.; and pressing said cellulose blank by means of said forming mould with a forming pressure acting on the cellulose blank across said forming surface, said forming pressure being in the range of 1 MPa to 100 MPa.
METHOD OF MAKING A DISPENSER
A method of making a dispenser includes: mixing a plurality of materials, the materials including plant fiber, vegetable gum, starch, a toughening agent, and a dispersing agent; utilizing a granulator to form the mixture of the plant fiber, the vegetable gum, the starch, the toughening agent, and the dispersing agent into pellets; and forming a dispenser by moving the pellets into a processing machine; wherein the processing machine melts the pellets and disposes the melted material into a cavity configured as a forming mold, and after cooling the dispenser is obtained.
METHOD FOR MANUFACTURING A CELLULOSE PRODUCT, CELLULOSE PRODUCT FORMING APPARATUS AND CELLULOSE PRODUCT
A method for manufacturing a cellulose product, comprising the steps: dry forming a cellulose blank in a dry forming unit; arranging the cellulose blank in a forming mould; heating the cellulose blank to a forming temperature in the range of 100° C. to 200° C.; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.
Method and device for connecting fibre-reinforced webs
A process for joining two sheeting articles reinforced with unidirectionally aligned endless-fibres by ultrasonic welding, wherein the fibres are embedded in a matrix of polycarbonate and the sheeting articles have abutting ends that are substantially rectangular and substantially even. The process comprises (1) arranging the sheeting articles next to one another end-to-end in the region of the abutting ends in a welding apparatus between a sonotrode and an anvil, (2) welding the sheeting articles by means of ultrasound, wherein the sonotrode and the anvil exert pressure on the to-be-welded sheeting articles in the melting region between the sheeting articles and perpendicularly to the abutting ends of the sheeting articles, and (3) removing the sheeting articles that are welded to one another from the welding apparatus. Also provided is a second process for joining two sheeting articles, a sheeting article, an apparatus, and a multilayer composite.

Embodiments herein include compositions, extruded articles, and methods of making the same. In an embodiment, an extruded article is included. The extruded article can include an extruded segment comprising a first composition. The first composition can include a polymer resin, particles and fibers. The fibers can be disposed within the first composition exhibiting a substantially non-aligned directional orientation. In an embodiment, an extruded article is included having a first portion comprising a first composition having a first fiber orientation and a second portion comprising a second composition having a second fiber orientation. The first composition can include a polymer resin and fibers. The second composition can include a polymer resin, particles and fibers. The fibers of the second composition can be oriented more randomly than the fibers of the first composition. Other embodiments are also included herein.
Thermoformed article with co-injected features
A thermoformed article is disclosed that includes a self-supporting structural base layer, a covering applied to a first side of the base layer, and one or more secondary features co-injected upon a second side of the base layer. The covering and the secondary features of the thermoformed article are applied to the base layer during the same molding operation. Also disclosed is a process for forming a thermoformed article that includes placing a covering in a mold tool as a first layer, placing a self-supporting structural base layer in the mold tooling as a second layer, closing the mold tooling with the covering and base layer, and co-injecting upon a side of the base layer opposite to the covering one or more secondary features.
COMPOSITE MATERIALS
The invention relates to a composite material comprising cellulose. The composite material comprises a first cellulose-based material, which may be a textile or fabric, and a second cellulose-based material, which may be a film or cellulose based material or powdered cellulose-based material. The second cellulose-based material may be a sheet material comprising cellulose, such as a paper or a regenerated cellulose film. In embodiments the material is a so called “all cellulose composite” where both of the materials that are brought together are different forms of material comprising or being cellulose. For example, the different materials originate from cellulose-based feedstocks. The invention also relates to a process for preparing the composite materials of the invention utilising ionic liquids.
Unified Prefinished Panel
A product and a method of manufacture and assembly of a prefabricated wall panel for construction is shown and described. The present invention is directed towards minimizing the labor of multiple additive steps using many layers and materials seen in many building envelopes.
In one example, the method comprises,
A series of prefabricated residential or commercial building panels made of any of varying materials such as hemperete, fiber, cellulose, plant material, bio-aggregate, aggregate, aerated concrete, composite or inorganic materials, of substantially solid body with channel shaped elongated voids substantially located at the vertical sides as well as horizontally across their top.
Said voids in one panel are a connected channel wrapping around 3 or more sides of the panel and exposed to the exterior of said panel. Said panels are placed side by side around the perimeter of a foundation aligning the channel shaped void in one panel with the respective channel shaped void in the panel beside it creating a concrete form, or form for a load bearing material. Said panels are left in place as an integral part of the wall system. Concrete or other load bearing material is placed in said voids substantially vertically between the panels and across their tops creating an air seal and a mechanical bond between panels. The resulting concrete shape inside the wall is a post and beam structure that is substantially equidistant from the interior and exterior of the wall minimizing heat transfer through thermal bridging and minimizing weathering to the concrete. Many of the requirements of a building's wall such as the insulation, the shear strength, the rough openings for windows and doors, the interior and exterior skin, utility chases, drip edges and trim details can be met by this series of prefabricated building blocks. A method of manufacture of the building panels, the product created by that manufacture, a method of panel assembly and integration with other building components, and the finished product created by the manufacture, assembly and integration with other building components are all shown in the present disclosure.
Methods of producing thermoplastic composites using fabric-based thermoplastic prepregs
A thermoplastic product includes a fabric-based reinforcing sheet and a polymerized thermoplastic material. The fabric-based reinforcing sheet is wound about a mandrel to form a plurality of layers having a cross-sectional shape that corresponds to the mandrel. The fabric-based reinforcing sheet includes a plurality of fiber bundles, which may have a bidirectional orientation or configuration. A polymerized thermoplastic material is disposed within each layer of the fabric-based reinforcing sheet. The polymerized thermoplastic material bonds each layer of the fabric-based reinforcing sheet to an adjacent layer.
