Publication number: 20240209549Abstract: A method of making a sized and resin-coated fiber tow for use in a fiber reinforced composite. the method comprising the steps of providing a fiber, contacting at least a portion of the fiber with a sizing slurry to form a sized and resin-coated fiber, the sizing slurry comprising 0.1-25% by weight of a sizing agent and 20-80% by weight of a matrix-resin powder in a solvent, based on the total weight of the sizing slurry. wherein the total solid content, including the sizing agent and the matrix-resin powder, of the sizing slurry is greater than 30 wt. %. The method further comprising drying the sized and resin-coated fiber at a temperature below the melting point of the matrix-resin powder, thereby forming a dried sized and resin-coated fiber and winding the dried sized and resin-coated fiber onto a spool.Type: ApplicationFiled: April 8, 2022Publication date: June 27, 2024Applicant: Zoltek Companies, Inc.Inventors: Maurice Geli, David Michael Corbin

Publication number: 20220281707Abstract: A fiber guide that guides fibers in a fiber processing system. The fiber guide has a surface having apertures through which fibers can pass in a direction from an upstream side of the surface to a downstream side of the surface. The apertures include at least one pair of apertures adjacent to and spaced from one another. The inlet of the first aperture is offset from the inlet of the second aperture. The offset is in the direction in which the fibers pass from the upstream side of the surface to the downstream side of the surface. A distance (d1) between the inlet of the first aperture and the inlet of the second aperture is larger than a distance (d2) between the first aperture and the second aperture measured transverse to the direction in which the fibers can pass.Type: ApplicationFiled: August 6, 2020Publication date: September 8, 2022Applicant: Zoltek CorporationInventors: Maurice GELI, Arpad RUMY

Patent number: 10907754Abstract: A composite strip which extends in a main direction between first and second ends and which comprises a main strip comprising first fibres embedded in a matrix. The first fibres are made of carbon, an electrically conducting material, and the matrix is made up of at least one polymer. The composite strip further comprises a junction layer formed of an electrically conducting junction material. The junction layer is placed on the main strip.Type: GrantFiled: December 2, 2014Date of Patent: February 2, 2021Assignee: TOTAL SAInventors: Alexandre Lewandowski, Franck Rey-Bethbeder, Dominique Delaporte, Alain Lechon, Maurice Geli, Yann Buzaré

Patent number: 10283925Abstract: A method for forming an electrical connection in a pipe for transporting a fluid. The pipe comprises an internal hollow tube and a heating layer comprising first fibers made of carbon. There are performed a groove-formation step in which a groove is formed in the heating layer, an interface-preparation step in which a junction layer is placed on the heating layer of the groove, and a placement step in which a connection strip comprising second fibers formed of a second electrically conducting material is wound on the junction layer.Type: GrantFiled: December 2, 2014Date of Patent: May 7, 2019Assignee: Total SAInventors: Alexandre Lewandowski, Franck Rey-Bethbeder, Dominique Delaporte, Alain Lechon, Maurice Geli, Yann Buzaré
