A thermoplastic composite article comprising a porous core layer and a textured film disposed on a first surface of the porous core layer is described. The composite article can be configured as a recreational vehicle building substrate such as a ceiling or interior wall panel.

Protective clothing materials and related methods and garments are provided. In some embodiments, a protective clothing material may comprise a fibrous layer that serves as a barrier to certain fluids (e.g., bodily fluids, water) and microbes. The impermeability of the fibrous layer may be due, at least in part, to the structural uniformity and/or relatively small pore size of the fibrous layer. In some embodiments, the fibrous layer may have a relatively high air permeability that imparts beneficial properties (e.g., relatively high air flow, breathability) to the protective clothing material without adversely affecting its protection rating. In certain embodiments, the protective clothing material may also comprise one or more coarse nonwoven webs that impart beneficial properties (e.g., splash resistance) to the protective clothing material. The protective clothing materials, described herein, may be particularly useful for a wide variety of applications, including the formation of AAMI level 4 protective garments.

A form-stable composite material with two flexible layers, between which is accommodated a layer with fiber-reinforced recycled ground material, comprising thermoplastically bound fibers, wherein grains of the ground material are firmly bonded to one another and to the flexible layers, the layer of ground material being porous.

A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.

A reinforced water-resistant board includes a cover board with a reinforced water-resistant membrane applied to a surface of the cover board. The reinforced water-resistant membrane includes a primer layer, a reinforced membrane, a traffic coat, and a sealing layer. The primer layer is applied over the surface of the cover board. The reinforced membrane includes fleece soaked in a liquid resin and is applied over the primer layer. The traffic coat is bonded to the reinforced member. The sealing layer is applied over the traffic coat.

The invention relates to a tubular liner for the rehabilitation of an, in particular, underground sewer pipe, comprising at least an inner tubular film, a resin-carrier layer surrounding the inner tubular film, and comprising a mechanically protective outer film system. The outer film system comprises at least one outer film in the form of a UV-radiation- and short-wavelength, visible light-absorbing and/or -reflecting, single-layer or multi-layer film which contains, in one or more polymer layers, at least one short-wavelength, visible light-absorbing and/or—reflecting, organic or inorganic color pigment or a corresponding dye, and at least one organic or inorganic compound which absorbs and/or reflects the UV radiation. Moreover, the outer film system comprises at least one mechanically stable reinforcing web which rests on the aforementioned outer film. The outer film system has a transmittance for visible light at at least one wavelength in the range of 550 nm to 800 nm of at least 1%. The invention also relates to a method for manufacturing such an outer film system and to such an outer film system itself.

A composite board comprising (i) a first foam region; (ii) at least one fragile insulating material; and (iii) a second foam region, where said second foam region is substantially devoid of hydrocarbons.

A resin coated copper according to an embodiment includes: an insulating layer including a resin and a filler dispersed in the resin; and a copper foil layer disposed on the insulating layer, wherein the insulating layer has a plurality of pores formed on a surface in contact with the copper foil layer, and the plurality of pores have a width of 200 nm to 350 nm.

The present disclosure generally relates to systems and methods for composites, including short-fiber films and other composites. In certain aspects, composites comprising a plurality of aligned fibers are provided. The fibers may be substantially aligned, and may be present at relatively high densities within the composite. For example, the composite may include substantially aligned carbon fibers embedded within a thermoplastic substrate. The composites may be prepared, in some aspects, by dispersing fibers by neutralizing the electrostatic interactions between the fibers, for example using aqueous liquids containing the fibers that are able to neutralize the electrostatic interactions that typically occur between the fibers. The liquids may be applied to a substrate, and the fibers may be aligned using techniques such as shear flow and/or magnetism. Other aspects are generally directed to methods of using such composites, kits including such composites, or the like.

In a method for producing a fiber-reinforced resin molded body (10) by heat-compressing fiber substrates (11A to 11D) together with a thermosetting resin (15) so that the thermosetting resin (15) is impregnated into the fiber substrates (11A to 11D) and cured, a thermosetting resin powder (15A) is disposed in contact with at least one surface of the fiber substrates (11A to 11D), the fiber substrates (11A to 11D) are heat-compressed together with the thermosetting resin powder (15A) by a mold (30) so that the thermosetting resin powder (15A) is melted, impregnated into the fiber substrates (11A to 11D), and cured. Also disclosed is a fiber-reinforced resin molded body as well as a vehicle or airframe including a fiber-reinforced resin molded body.
