Method for incorporation of optical fibres, or rather optical fibre sensors, inside products manufactured from composite material

摘要

Method which allows the introduction, the incorporation, and the emergence of optical fibres inside a piece of composite material, during the manufacturing process. The incorporation of the optical fibres is done in order to allow a diagnosis of mechanical, thermal, chemical quantities inside the piece. The method of incorporation calls for the use of a tool suitable for passing through the composite material in the entry/exit zones of the optical fibre and, furthermore, calls for the use of an adhesive material based on synthetic rubber, compatible with the composite material, in the same entry/exit zones. Such a solution has the advantage of maintaining the integrity of the optical fibre in the critical entry/exit zones, and furthermore allows an easy handling of same for subsequent necessary connections to suitable instruments/apparatus of measurement and/or inspection of structures made of composite material (Smart Structures).
