Abstract: The object of the invention is a process for the production of a fiber-based armature particularly adapted to be embedded in at least one matrix, characterized in that it consists in performing the following steps: preparing a fiber-based material, and depositing on at least one of the surfaces of the material thus obtained a repositionable glue. The invention also covers the obtained armature.

Abstract: 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.

Abstract: The object of the invention is a process for production of a reinforcement (10) for composite material comprising at least two layers (12, 14) intended to be embedded in a polymer matrix, characterized in that at least one (14) of the layers is comprised of continuous filaments (16) in one main direction F and in that these filaments are positioned with variable spacing along this main direction F.

Abstract: A method for making a fiber reinforcement designed in particular to be incorporated in at least one matrix, characterized in that it includes performing the following steps: preparing a fiber-based material, and depositing on at least one of surfaces of the resulting material an adhesive capable of being reposition. Also, the reinforcement resulting from this method.
