Abstract: The invention relates to a method for producing an OSB, wherein a scattered mat formed by strands adhered in multiple layers is pressed in a hot press to form a panel with a desired thickness, comprising the following steps: a) scanning the surface of an upper side of the mat or of the pressed panel to determine uneven areas and/or faults; b) determining position data of the determined uneven areas and/or faults; c) determining the volumes of the individual uneven areas and/or faults; d) targeted filling of the uneven areas and/or faults with a filling material, based on the determined position data and volumes, wherein e) the filling material is scattered with a scattering device.

Abstract: A foam form sheet material having a first large surface comprising substantially only closed cells and an opposite large surface and an interior comprising substantially only open cells. This material comprises a cross linked olefin thermoplastic polymer or copolymer. The foam is made by mixing the polymer with a blowing agent and a cross linking agent. The mixture is maintained in a two roll mill means for a time sufficient to initiate cross linking and to initiate foaming to form closed cells. The sheet material is then disposed in a second two roll mill means having a nip that is larger than the thickness of the foamed sheet material and maintained under elevated temperature and pressure sufficient to initiate further cross linking and foaming. The fully cross linked cell foam is then compressed to rupture the closed cells that are disposed in the interior to form open cells.

Abstract: A method of the present disclosure includes of repairing a core stiffened structure with structural foam. Another method includes splicing core members together using structural foam. Another method includes joining a core member to a structure using structural foam. Another method includes using structural foam to stabilize a core member during a machining process. Another method includes stabilizing a core member with structural foam to prevent the core member from crushing in autoclave pressure. The present disclosure further includes a core stiffened structure have a core member with structural foam therein.

Abstract: A method for repairing a hollow fiber membrane in a module in which ends of a plurality of hollow fiber membranes are secured to a side of the module. A method for repairing a hollow fiber membrane in a module includes bringing a filler material that is in a solid phase into contact with a damaged portion of the hollow fiber membrane, and heating a filler contact site to join the filler material to the hollow fiber membrane, and the filler material is in solid phase.

Abstract: The present invention provides a method for the localized working of a structural component that comprises a foam material reinforced by at least one strut at a working location. Firstly, the foam material is selectively removed, while leaving the at least one strut, within a strut connecting zone in the region of the working location. Subsequently, the strut connecting zone is filled with a filling material and the at least one strut is connected to the filling material in the strut connecting zone. From a further aspect, a sandwich component which comprises a foam core is provided. An embedding part is at least partially embedded in the foam core and at least partially surrounded by a layer of filling material. At least one strut is incorporated in the foam material, fastened at one end to the surface of the foam core and integrated at another end in the layer of filling material.

Abstract: A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

Abstract: A method for making a porous material, includes melt-blending two or more non-miscible polymers to obtain a co-continuous melt, solidifying the melt to obtain a solid mass consisting of two co-continuous polymer phases, and selectively extracting one of the co-continuous phases thereby creating within the solid mass an essentially continuous pore network having an internal surface. The method further includes replicating the internal surface of the pore network within the solid mass by coating the internal surface with successive layers of materials, and selectively extracting the solid mass without extracting the layers of materials, to thereby yield the product porous material, formed of the layers of materials. The material has a void fraction higher than about 75%, and mainly having essentially fully interconnected sheath-like non-spherical pores and essentially non-fibrous walls.

Abstract: A method of recycling cured foam insulation having an internal cell/bubble structure is described. The method comprises cutting the cured foam cell insulation into foam pieces of predetermined sizes and shape dependent on the dimensions of cavities to be insulated and incorporating the foam pieces therein. A predetermined volume of the cavities is filled with the foam pieces and a predetermined quantity of an expandable liquid foam insulation is injected into the cavities containing the foam pieces and caused to expand to fill voids in the cavities with the foam pieces forming a homogeneous insulating foam body throughout the cavities while retaining substantially their internal cell/bubble structure.

Abstract: A process for extending the cyclic service life of thermal barrier coatings made of yttrium-stabilized zirconium oxide (YSZ) or the like which have been applied to a substrate with an oxidizing bond coat in between includes increasing or long-term stabilizing the strain tolerance of the thermal barrier coating.

Abstract: A method of fabricating a highly porous structure is provided. The method includes the step of compounding a biodegradable polymer, a water-soluble polymer and a porogen to form a composite blend. A foaming agent is dissolved into the composite blend and the composite blend is injected into a mold so as to form the structure. Thereafter, the structure is removed from the mold and leached in a fluid.

Abstract: A technique and tool are provided for repairing damaged areas of honeycomb structures. The tool includes a plurality of rods axially translatable into the damaged area. Foam material is inserted about the rods and allowed to cure. The rods are later withdrawn leaving a porous core of material. Sleeves may be provided to receive and support the rods as they translate into the damaged area. The sleeves may remain in the damaged area after the rods are withdrawn into the sleeves.

Abstract: Silica-based refractories are impregnated with protective material that is more resistant towards attack by corrosive species. The protective material coats the surface of the refractory matrix and fills some of the cavity volume of its pores, crevices, surfaces imperfections and irregularities. The protective material is positioned by impregnating the refractory with a precursor which, under the input of energy, is converted into the corrosion resistant protective material.
