Publication number: 20170348921Abstract: A 3-dimensional high-strength fiber composite component having isotropic fiber distribution, comprising 25 to 70 wt % of high-strength, high-modulus fibers, up to 5 wt % of binding fibers, and 25 to 70 wt % of thermosetting or thermoplastic matrix. The invention further relates to a method for producing same, comprising the following steps: preparing the fibers by opening the fibers by releasing the fibers from fiber bundles, bales, or textile structures; sucking and/or blowing the opened fibers onto a three-dimensional, air-permeable tool half having the contour of this side of the component in an interactively controlled manner; pre-solidifying the obtained fiber molding in the flock box; transferring the fiber molding onto a pressing tool in the form of the contour of the air-permeable tool half of the component; bringing into contact with at least one liquid plastic; and solidifying the fiber molding by pressing in order to form a component.Type: ApplicationFiled: January 6, 2016Publication date: December 7, 2017Applicant: HP PELZER HOLDING GMBHInventors: Norbert NICOLAI, Reimund PIATKOWSKI, Lino Mondino, Heinrich GRIMM, Volkmar SCHULZE

Publication number: 20160108511Abstract: A method for spray-coating substrate surfaces, in which (a) a thermoplastically processable material is molten and thus liquefied in an extruder in a first step; (b) the molten material is pressurized by means of a carrier gas or vapor; (c) a mixture formed from said molten material and said carrier gas or vapor is pressed through one or more nozzles, optionally supplying a spraying gas having a temperature at least as high as the melt temperature to the spraying jet in the region of the discharge opening of the nozzle; and (d) the obtained spray jet with the molten material is directed onto the substrate surface, wherein the material impinges in drops in a flowable state onto the substrate surface, forms a continuous coating on the substrate surface, and subsequently solidifies.Type: ApplicationFiled: May 6, 2014Publication date: April 21, 2016Applicant: HP PELZER HOLDING GMBHInventors: Norbert Nicolai, Volkmar Schulze, Thomas Karcz, Sergej Kohlert, Joachim Meyke, Holger Schaarschmidt, Toni Nippe, Christian Urban

Patent number: 8950548Abstract: The invention relates to a broadband sound absorber (1) which comprises a sound-absorbing filler material between two microperforated film webs (2) which are contiguous on their edges, said filler material optionally containing heavy fillers. The broadband sound absorber (1) achieves excellent acoustic insulation and has microperforations (4) all over or only in sections, said filler material optionally containing heavy fillers (mass density) and one or both microperforated film webs (2) having the same thickness across their surface or thickened portions (3, 5) of the same or a different material in some sections.Type: GrantFiled: January 28, 2011Date of Patent: February 10, 2015Assignee: HP Pelzer Holding GmbHInventors: Marco Schneider, Dirk Jaeger, Volker Kursch, Edmund Sumann, Norbert Nicolai, Volkmar Schulze

Publication number: 20130187076Abstract: The present invention relates to filled thermoplastic polyolefin compositions useful e.g., as sound-deadening sheeting for formed automotive applications comprising a propylene polymer having a density equal to or greater than 0.885 g/cm3, one or more linear ethylene polymer and/or substantially linear polymer, a plasticizer, and a filler, preferably calcium carbonate. Said composition demonstrates a good balance of heat properties and stiffness such that it is particularly suitable for sheet extrusion and thermoforming articles therefrom.Type: ApplicationFiled: November 19, 2010Publication date: July 25, 2013Applicants: HP PELZER HOLDING GMBH, DOW GLOBAL TECHNOLOGIES LLCInventors: James T. Seliskar, James D. Oelberg, Tariq S. Oweimreen, Paul M. Sowers, Thomas Karcz
