Patent number: 10550238Abstract: The invention relates to a process for preparing a gelled, dried composition forming a monolithic aerogel with a heat conductivity of less than or equal to 40 mW·m?1·K?1 and derived from a resin of polyhydroxybenzene(s) and formaldehyde(s), to this aerogel composition and to the use thereof. This process comprises: a) polymerization in an aqueous solvent of said polyhydroxybenzene(s) and formaldehyde(s) in the presence of an acidic or basic catalyst, to obtain a solution based on the resin, b) gelation of the solution obtained in a) to obtain a gel of the resin, and c) drying of the gel to obtain a dried gel. According to the invention, step a) is performed in the presence of a cationic polyelectrolyte dissolved in this solvent, and the process also comprises a step d) of heat treatment under inert gas of the dried gel obtained in step c) at temperatures of between 150° C. and 500° C.Type: GrantFiled: April 11, 2014Date of Patent: February 4, 2020Assignee: HUTCHINSONInventors: Bruno Dufour, Benjamin Swoboda, Cedric Huillet, Florian Fannechere, Nadine Poupa

Publication number: 20190283860Abstract: The invention relates to the thermal creation of a part, including steps of: using at least one first and one second metal plate (30, 31), hollow-forming the first plate so as to form at least part of said inner wall, and hollow-forming the second plate (31) so as to form at least part of said outer wall. During the forming, the shapes of the first and second plates are adjusted such that they can be placed in contact with each other while leaving a space therebetween inside said periphery, and then the first and second plates are placed in a low-pressure and/or controlled-atmosphere chamber (65), where said plates are brought together and peripherally sealed together such that, in said space, a low-pressure and/or controlled-atmosphere enclosure is created.Type: ApplicationFiled: December 2, 2016Publication date: September 19, 2019Applicant: HutchinsonInventors: Fabrice Chopard, Mathieu Leborgne, Cédric Huillet, Thomas Patillaut, Hmad Bourass, Yann Favier, Christophe Dominiak
