Publication number: 20200215727Abstract: The present invention relates to a process for the production of a structured grain on the surface of a thermoplastic having continuous-fiber reinforcement by a textile sheet, where a mixture of at least one fiber material and of at least one thermoplastic is heated and pressed in a mold to a temperature above the softening point of the thermoplastic, where a structured grain has been applied on the internal side of the mold. The at least one fiber material comprises continuous fibers and takes the form of a regularly arranged textile sheet. The textile sheet and the structured grain on the internal side of the mold are oriented in relation to one another in a manner such that during the pressing procedure the textile sheet and the structured grain on the internal side of the mold are mutually superposed.Type: ApplicationFiled: July 19, 2018Publication date: July 9, 2020Applicant: BASF SEInventors: Tim DIEHLMANN, Andreas RADTKE, Ulrich SCHNEIDER, Reinhard JAKOBI

Patent number: 10232556Abstract: The invention relates to a process for the production of at least two-layer thermoplastic sheets via thermal welding of at least one thinner thermoplastic sheet with density (D1) and of at least one second thinner thermoplastic sheet with density (D2), where the density (D1) of the first thinner thermoplastic sheet is smaller than the density (D2) of the second thinner thermoplastic sheet. The process introduces at least one first heating element and at least one second heating element along mutually offset planes between the two thinner thermoplastic sheets, where the surfaces of the thinner thermoplastic sheets do not touch the surfaces of the heating elements. The first heating element transfers a quantity of energy (E1) to the surface of the first thinner thermoplastic sheet, and the second heating element transfers a quantity of energy (E2) to the surface of the second thinner thermoplastic sheet, where the quantity of energy (E1) is smaller than the quantity of energy (E2).Type: GrantFiled: December 17, 2015Date of Patent: March 19, 2019Assignee: BASF SE (Ellwanger & Baier Patentanwälte)Inventors: Eckhard Neufeld, Carsten Sandner, Tim Diehlmann, Franz-Josef Dietzen, Dietrich Scherzer

Patent number: 10000014Abstract: The present invention relates to a process for the production of at least two-layer thermoplastic foam sheets via thermal welding of at least two thinner thermoplastic foam sheets. In the process of the invention, at least two heating elements are conducted on mutually offset planes between the surfaces to be welded of the thinner thermoplastic foam sheets, and the foam sheets here do not touch the heating elements. The number of layers of the thermoplastic foam sheet is per se a result of the number of thinner thermoplastic foam sheets that are thermally welded to one another. If by way of example three thinner thermoplastic foam sheets are thermally welded to one another, a three-layer thermoplastic foam sheet is per se obtained, and if there are four thinner thermoplastic foam sheets the result is accordingly per se a four-layer thermoplastic foam sheet.Type: GrantFiled: July 17, 2014Date of Patent: June 19, 2018Assignee: BASF SEInventors: Dietrich Scherzer, Tim Diehlmann, Franz-Josef Dietzen, Carsten Sandner, Herbert Schall
