Abstract :

The production of composite parts in France currently suffers from a lack of competitiveness within Europe and worldwide, due to high labor costs and low automation of manufacturing processes, limiting production volumes. One of the solutions and area of progress is to bring value to these heterogeneous structures through the integration of new functions : display, lighting, sensors, human-machine interface, material health control, etc. By advantageously combining the advantages specific to composite structures (lightness, durability, freedom of design, compatibility with small series, etc.) and recent progress in electronic devices (miniaturization, flexibility, low consumption, etc.), it is possible to create products with high added value and therefore more competitive.
This PhD work in collaboration between the Technical Center for Plastics and Composites (IPC) and engineering schools of the ISAE group, ESTACA and SUPMECA, carried out within the doctoral school of Mechanical and Energetic Sciences, Materials and Geosciences (SMEMAG) proposes to bring new knowledge on the possibilities and the potential of these smart composites in particular of the applications of SHM and the durability of these new composites.
For this, instrumented composites will be manufactured, the traditional manufacturing processes will have to be adapted and optimized according to the integrated applications. These fabrications will be supported by process/impregnation or interface simulations. An important point will be brought on the mechanical aspects of these new composites to have knowledge on their durability and the negative impact of the integration of a foreign element (functionalization) in a host structure (composite).
