The disclosure provides compositions adapted for oral use and, in particular, multi-compartment oral pouched products including such compositions. Some aspects of the disclosure relate to oral pouched products including a composition adapted for oral use within a porous pouch. In particular, the porous pouch may include two or more compartments, each compartment having a content of the composition contained therein. The composition within each compartment can be different such that the composition within each compartment provides a different functional or sensory experience, such as through use of a different flavoring agent, a different active ingredient, or both a different flavoring agent and a different active ingredient.

A method of fabricating a composite material, the method comprises the steps of a) providing a first layer of a fibre reinforced polymer, preferably a thermoset FRP, b) providing an array of thermoplastic islands across at least a proportion of a major surface of the first layer, c) providing a second layer of a fibre reinforced polymer, preferably a thermoset FRP, d) laying the second layer over at least some of the islands, and e) securing the first and second layers together. There is also disclosed a composite which comprises a first layer of a fibre reinforced polymer and a second layer of a fibre reinforced polymer, between which is an intervening layer comprising an array of thermoplastic islands.

A hybrid metal composite (HMC) structure comprises tiers comprising fiber composite material structures, and additional tiers longitudinally adjacent one or more of the tiers and comprising perforated metallic structures and additional fiber composite material structures laterally adjacent the perforated metallic structures. Methods of forming an HMC structure, and related rocket motors and multi-stage rocket motor assemblies are also disclosed.

Methods of making bearings using pressure sensitive macromolecular adhesive polymers and pressure sensitive polymer compositions capable of integrating fluoropolymeric properties with a catecholamine functionality to form an adhesive system that allows bonding between metallic substrates and fluoropolymers are disclosed. Also disclosed are core-shell polymeric particles comprised of a core and a shell comprising a thermoplastic polydopamine polymer that may be prepared as a colloidal suspension and used as a hot-melt pressure sensitive adhesive capable of binding low surface energy materials, such as polyolefins and fluoropolymers, to diverse materials including metals in making bearings and/or bearing components.

Provided are a sub-micron fibrous membrane in which sub-micron fibers aligned along one axis and sub-micron fibers in a random pattern form a network, and a method for producing the sub-micron fibrous membrane.

A bacterial cellulose-based air filter mesh and use thereof are disclosed. The bacterial cellulose-based air filter mesh comprises a three-layer structure, in which a layer of a bacterial cellulose-based filter mesh is sandwiched by two layers of polymer fiber filter meshes; wherein the polymer fiber filter mesh is a mesh having a uniform grid size formed from polymer fibers by blended-yarn weaving; and the bacterial cellulose-based filter mesh is formed by in-situ synthesis of bacterial cellulose on a non-woven fabric through fermentation by bacteria. The bacterial cellulose-based air filter mesh has better particle filtering effect, better formaldehyde adsorption capacity, better antibacterial performance and good electrostatic capacity; and it can be used for producing gauze windows, air conditioning filters, air purification filters and the like, and has a wide range of applications.

An example composite building material includes one or more layers of polymeric fibers, binding agent, and optional fillers, and at least one surface layer of resin-impregnated paper disposed above and/or below the one or more layers. The one or more layers can include a core layer with longer polymeric fibers and top and bottom layers with shorter polymeric fibers. A method of manufacturing the composite building material includes forming the one or more layers, applying the at least one surface layer above and/or below the one or more layers, and heating and pressing the combined layers.

The present disclosure relates to an step artificial leather having visual penetration and a manufacturing method thereof. The artificial leather includes a thermoplastic substrate, a thermoplastic adhering layer, and a thermoplastic surface layer. The thermoplastic substrate has fiber net shape, and has visual penetration. The thermoplastic adhering layer is disposed on the thermoplastic substrate. The thermoplastic surface layer is disposed on the thermoplastic adhering layer. The thermoplastic surface layer and the thermoplastic adhering layer are transparent. Therefore, the artificial leather of the present disclosure has visual penetration effect. The product made from the artificial leather of the present disclosure has attractive appearance and diversity.

The present disclosure provides for protective drainage wraps having improved properties, including fluid handling and structural integrity. The protective material barrier constructions, such as wraps, provide protection to surfaces, such as walls of buildings. The present disclosure provides for methods of making, using, and installing such protective material barrier constructions.

The method for producing a skin material is a method for producing a skin material having a concave part formed on the front surface side, comprising heat-pressing a raw material between an embossing die and an elastic sheet to form the concave part and, at the same time, forming a convex part on a bottom surface of the concave part.
