Method for making a core having built-in cross-linking fibers for composite material panels, resulting panel, and device

摘要

The invention relates to a method for making a core (10), having built-in cross-linking fibers (12), for manufacturing composite panels, said method being characterized in that it consists of carrying out the following steps: gaining access to a bar made of a light rigid foam material that forms the core (10); depositing an excess of cross-linking fibers (12) onto at least one surface (18, 20) of the core; feeding a portion of said cross-linking fibers (12) into the core; and removing the unused excess of cross-linking fibers. The invention also relates to the resulting panel, as well as to the related device.
