PROCESS FOR THE PRODUCTION OF A STIFFENER THAT IS SCOOPED OUT IN THE SHAPE OF AN OMEGA AND CORE FOR THE PRODUCTION OF A STIFFENER THAT IS SCOOPED OUT IN THE SHAPE OF AN OMEGA

摘要

A process for obtaining a core for the production of a stiffener (12) on a surface (14) of an element (10) that is to be made rigid, whereby the core is able to be placed between the element (10) to be made rigid and the stiffener (12) so as to obtain a cavity, includes steps of: Producing a central part (20) whose geometry is adapted to that of the cavity, whereby the central part (20) is made of a material that can dissolve or disintegrate; Inserting the central part (20) into an envelope (22) that is made of a thermo-retractable material; and Heating at least the envelope (22) so as to obtain its retraction around the central part (20).
