A method for manufacturing a rotor blade of a wind power plant which has an area close to the blade root in which the rotor blade has an obtuse rear edge. The method includes manufacturing a half-shell on the pressure side and a half-shell on the suction side, introducing and adhesively bonding filler bodies into at least one section of the area of the obtuse rear edge of the pressure-side half-shell and the suction-side half-shell, wherein the sections with the filler bodies lie opposite one another in the assembled rotor blade, assembling and positioning the half-shells relative to one another, wherein an adhesive gap which is delimited by the first adhesive surfaces of the filler bodies remains between the filler bodies, and introducing an adhesive medium into the adhesive gap. Also a rotor blade manufactured according to the method, and a wind power plant including such a rotor blade.

A double pull tab stretch releasing adhesive tape having first and second pull tabs residing at first and second distal ends of an extensible tensile sheet. The first and second pull tabs have a plurality of anti-slip grip regions that enable a secure gripping hold by an end user. The double pull tab stretch releasing adhesive tape attaches two substrates together and is removed by simultaneously pulling the first and second pull tabs in opposing directions to generate a two-way stretching force along the longitudinal length. This force is exerted on and stretches the extensible tensile sheet to distort the first adhesive for removal of the double pull tab stretch releasing adhesive tape from the first substrate without the end user touching any substrates.

A laser-welded body includes at least three of resin members, which contain a thermoplastic resin including: a first resin member which is a laser-irradiated subject, has an absorbance a.sub.1 of 0.01 to 0.12; a second resin member which has an absorbance a.sub.2 of 0.1 to 0.9 and includes a butted part where ends of one or more resin members are brought into contact with each other; and a third resin member which has an absorbance a.sub.3 of 0.2 to 3.8, and the absorbances a.sub.2, a.sub.3 exhibited by the second resin member and the third resin member are attributed to the inclusion of nigrosine as a laser beam absorbent therein, and the resin members are overlapped in the above mentioned to form contacted parts at these interfaces, at least a part of the butted part and/or the contacted parts are laser-welded.

There are provided a method of producing a laminate that is used to produce a fiber-reinforced composite material molded product having a complex shape, and a method of producing a fiber-reinforced composite material molded product having excellent appearance and mechanical characteristics and having a complex shape. The method of producing a laminate according to the present invention includes, in an assembly (50) having at least one selected from the group consisting of an abutment part in which ends of sheet-like prepregs are abutted so that side end surfaces come in contact with each other and an overlapping part in which ends of sheet-like prepregs overlap, laminating a sheet molding compound on at least a part of one or both of the abutment part and the overlapping part in an overlapping manner.

A jointed wind turbine rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint line. Each of the blade segments includes a pressure side shell member and a suction side shell member. A sealing tape is applied over the shell members so as to bridge across the chord-wise joint line. The sealing tape includes side edges that are aligned parallel with airflow over the shell members at the chord-wise joint line at a defined load and operational condition on the jointed wind turbine blade.

A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.

Described herein is an adhesive article for fire protection along with methods of using the same. The adhesive article comprises a substrate having a first major surface; an intumescent material fixedly attached to a central portion of the first major surface; and an adhesive layer disposed at least along two opposing distal portions of the first major surface.

A synthetic turf seam integration template system and method is provided that includes a template having a planar base including a longitudinal non-cutting edge and an opposing longitudinal cutting edge. The longitudinal cutting edge is not straight but has a predetermined curvature. In one aspect, a through-cut viewing slot extends longitudinally offset a predetermined distance from said non-cutting edge. Variations of the predetermined curvature patterns are disclosed. An optional connector allows connection of two templates to create a longer template for usage on longer seams. Also disclosed are methods of using the seam integration tool in creating an undetectable seam in synthetic turf.

A method for joining two carpet segments, each carpet segment having an underside and at least one edge, comprises abutting one edge of one carpet segment with one edge of the other carpet segment, positioning a length of seam tape under the abutting edges, and activating the adhesive to secure the seam tape to the undersides of both carpet segments. The seam tape comprises an elongated base layer being resilient in a longitudinal direction, an intervening layer applied to the base layer, and an adhesive applied to the intervening layer.

A hinged component includes first and second portions of material coupled together by a composite live hinge. The live hinge includes a layer of tensile fabric and a layer of elastomer interposed between the tensile fabric and the material of one or both of the coupled first and second portions. The composite live hinge is capable of joining structural composite materials without the need for scoring, and thereby weakening, the structural composite material along the desired hinge line. The live hinge can be embedded in the materials it joins in a method that is compatible with traditional structural composite layup processes and in a manner which prevents resin from the structural composite materials from infiltrating the tensile fabric and compromising its flexibility.
