Method of manufacturing a wind turbine blade
The present invention relates to a method of manufacturing a wind turbine blade, comprising arranging one or more layers of fibre material and a preform in a mould (66), injecting the one or more layers of fibre material and the preform (76) with a curable resin, and curing the resin. The preform (76) is impregnated with a curing promoter such that the concentration of curing promoter varies spatially within the preform.
PLANAR COMPOSITE MATERIAL
A sheetlike composite material including at least one layer A of a nonwoven thermoplastic fiber web or a thermoplastic film, and at least two unidirectional oriented-fiber layers B and B′, the layers B and B′ having a bidirectional fiber orientation. The layers are not only needled but also stitched to one another.
Covering Panel and Process of Producing Covering Panels
The present invention provides a covering panel, such as a floor panel, wall panel or ceiling panel, comprising a substrate and optionally a top layer, whereby said substrate comprises a synthetic material and a filler material, whereby said filler material is comprised in an amount from 15 to 75 wt. % based on the total weight of said substrate. In addition, the present invention provides a process of producing such covering panels.
NONWOVEN FABRIC AND PROCESS FOR FORMING THE SAME
The present invention relates to a nonwoven fabric comprising a plurality of polypropylene-containing fibers that form a nonwoven web, which fibers in addition contain a slip agent, the web has a side which is provided with an alternating pattern which consists of individualized bonded areas which bonded areas are in the form of rods which are arranged in the cross direction of the web, the alternating pattern of individualized bonded areas defines a non-bonded area, the web has a basis weight on the range of from 5-25 g/m.sup.2, the surface of the bonded areas is in the range of 5-20% of the total surface of the side, and the surface of the non-bonded area is in the range of 80-95% of the total surface of the side. The present invention further relates to a process for forming the nonwoven fabric.
METHOD FOR PRODUCING A PRINTED DECORATIVE PAPER
The present invention relates to method for producing a printed decorative paper comprising the steps of: i) providing a substrate paper; ii) applying to said substrate paper a decorative layer; iii) applying to said decorative layer a liquid coating consisting essentially of a polymerizable mixture; iv) applying polymerization conditions to form a polymerized layer on said decorative layer. An object of the present invention is to provide a method for manufacturing a printed decorative paper, which decorative paper is processed to form a decorative panel, which decorative panel thus obtained will exhibit a good resistance against weather influences.
ABSORBENT ARTICLES COMPRISING GARMENT-FACING LAMINATES
An absorbent article is provided. The absorbent article comprises a liquid permeable topsheet on a wearer-facing side of the absorbent article and a garment-facing laminate on a garment-facing side of the absorbent article. The garment-facing laminate comprises a first nonwoven layer and a second layer joined to the first nonwoven layer. The first nonwoven layer comprises a plurality of apertures. At least 3 of the plurality of apertures in a repeat unit have a different Effective Aperture Area, according to the Aperture Test herein, a different shape, or a different Absolute Feret Angle, according to the Aperture Test herein. The absorbent article comprises an absorbent core disposed at least partially intermediate the liquid permeable topsheet and the garment-facing laminate.
AIR AND WATER BARRIER ARTICLES
There are provided rolls comprising an air and water barrier article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on at least the first major surface of the article, and a liner having a first major surface that contacts the opposing second major surface of the article, and at least two adhesion modifying zones disposed between the second major surface of the article and the first major surface of the liner, wherein both of a first and second adhesion modifying zones contact the first major surface of the liner, and wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll. There are also provided films made using these air and water barrier articles and building envelopes made using such films.
HIGH PERFORMANCE NONWOVEN STRUCTURE
The presently disclosed subject matter relates to multi-layer nonwoven materials and their use in absorbent articles. More particularly, the presently disclosed subject matter relates to layered structures that have high absorbency performance while having less absorbent mass than other commercially available materials.
ALUMINIZED FACED NONWOVEN MATERIALS
An acoustic material comprising one or more acoustic composite layers; and a facing layer, wherein the one or more acoustic composite layers are formed of a nonwoven sound absorption material; wherein the facing layer is permeable; and wherein the facing layer is attached to a top surface of the one or more acoustic composite layers. The facing layer may optionally include metallic components or a metallized outer surface. The acoustic material may optionally include a pressure sensitive adhesive material on an opposing side of the one or more acoustic composite Sayers to enable installation of the acoustic material. The facing layer may include a permeable scrim, a perforated film, or a perforated foil. The facing layer may be metalized on its top exposed surface to provide infrared heat reflection, and a corrosion resistant coating may be applied on top of the metalized layer if required to stabilize the metal coating.
ABSORBENT ARTICLE
Provided is an absorbent article having excellent shape retention of an absorber even when an external force is applied thereto. The present invention is an absorbent article having: an aqueous-liquid absorbing part having crosslinked polymer particles having as essential constitutional units thereof a water-soluble vinyl monomer and/or a vinyl monomer which became the water-soluble vinyl monomer by hydrolysis, and a crosslinking agent; and a nonwoven fabric having porous fibers as an essential constituent thereof, the crosslinked polymer particles preferably absorbing 40 times the weight thereof of physiological saline 40 in 40-150 seconds.
