Brief description of embodiments of a molding core and molding core for the manufacture of a complex piece of composite material

摘要

In order to produce a structure made of composite material comprising the elongated hollow shapes, such as hollows shapes, associated with the stiffeners of a rigid panel, of the nuclei comprising an elastomer bladder are réalisés.l' invention relates to a method of implementation of such cores can be withdrawn in order to obtain the cores of very great length and allowing the use of these cores for an industrial production of parts composites.la bladder is a bag which is shaped in a mold having a core, the core is not itself - even necessarily cylindrical, before being filled with a granular material and placed under vacuum to give the core a shape which is stable by compacting of the granular material.
