METHOD FOR MAKING A CORE HAVING BUILT-IN CROSS-LINKING FIBERS FOR COMPOSITE MATERIAL PANELS, RESULTING PANEL, AND DEVICE

摘要

A process for the production of a core (10) with integrated bridging fibers (12) for the manufacturing of composite panels, includes producing the following stages: using a cake that is made of light material of the rigid foam type, forming the core (10); depositing excess bridging fibers (12) on at least one surface (18, 20) of the core; making a portion of these bridging fibers (12) penetrate into the core; and removing excess bridging fibers (12) that are not used. The panel that is obtained as well as the associated device are also described.
