TRAITEMENT THERMIQUE UNIFORME DES COMPOSITES NON METALLIQUES AU MOYEN DE L'EFFET DIELECTRIQUE DE L'INVERSION DE L'ATTENUATION DES ONDES ELECTROMAGNETIQUES

Abstract : The objective of my thesis is the improvement of the heat treatment processes of the massive parts in composite materials with a thermoset matrix. From all the techniques available, heating by microwave is the technique which is the most attractive and therefore it was the one implemented. However the homogeneous treatment of parts of significant size by this technique poses certain problems. These problems are related to the possible existence of standing waves and to the attenuation of electromagnetic waves. The objective of this work is the improvement of this technique by optimizing the mold geometry and dimensions which makes it possible to reach a better homogeneity thanks to the dielectric effect of attenuation inversion of electromagnetic waves. The present subject requires a multidisciplinary approach, because it treats the creation of thermal sources. These sources are created by an electromagnetic field and that governs the chemical reactions kinetics. The solution suggested thus requires controlling the three areas, thermal, electromagnetic and chemical which happen here in a strongly coupled way.
