LE COMPORTEMENT A L'OXYDATION DES COMPOSITES 2D C/SIC EST ETUDIE SUR LE PLAN DE LA CINETIQUE DE PERTE DE MASSE, DES MODIFICATIONS MICROSTRUCTURALES EN COURS D'OXYDATION ET DE L'EVOLUTION DES PROPRIETES MECANIQUES EN TRACTION A L'ISSUE DES TRAITEMENTS OXYDANTS. DANS UN PREMIER TEMPS, UNE RELATION EST ETABLIE ENTRE LA MICROSTRUCTURE ET LE COMPORTEMENT A L'OXYDATION DES FIBRES DE CARBONE REVETUES DE PYROCARBONE DANS L'OBJECTIF DE DETERMINER LA CINETIQUE D'OXYDATION DU RENFORT FIBREUX ET DE LOCALISER LES ZONES LES PLUS SENSIBLES A L'ENVIRONNEMENT OXYDANT. PAR LA SUITE SONT DETERMINES LES MECANISMES RESPONSABLES DE LA CINETIQUE D'OXYDATION DES COMPOSITES 2D C/SIC ET DE LEUR EVOLUTION MICROSTRUCTURALE EN COURS D'OXYDATION. LA CONNAISSANCE DE CES MECANISMES A MENE A LA MODELISATION DE LA CINETIQUE D'OXYDATION DU COMPOSITE. CE MODELE EST UTILISE POUR ETUDIER L'INFLUENCE DES PRINCIPAUX PARAMETRES SUR LA CINETIQUE D'OXYDATION DU COMPOSITE, A SAVOIR: LA PRESSION DE L'ENVIRONNEMENT OXYDANT, L'EPAISSEUR DU REVETEMENT PARTIELLEMENT PROTECTEUR EN CARBURE DE SILICIUM ET LA PRESENCE D'UNE SOLLICITATION MECANIQUE. ENFIN, UNE CORRELATION EST ETABLIE ENTRE LES MODES DE DEGRADATION DU RENFORT FIBREUX ET LES MODIFICATIONS DU COMPORTEMENT EN TRACTION INDUITES PAR L'OXYDATION DES COMPOSITES 2D C/SIC

LA CONNAISSANCE DES MECANISMES D'OXYDATION DES COMPOSITES SIC/C/SIC EST ESSENTIELLE POUR L'UTILISATION DE CES MATERIAUX A HAUTES TEMPERATURES EN ENVIRONNEMENT OXYDANT. DANS CETTE ETUDE, SONT PRESENTEES DANS UN PREMIER TEMPS LES CINETIQUES D'OXYDATION DES FIBRES SIC EX-POLYCARBOSILANE ET DE LA MATRICE SIC DEPOSEE CHIMIQUEMENT A PARTIR D'UN MELANGE CH#3SICL#3/H#2. LE COMPORTEMENT A L'OXYDATION DES COMPOSITES SIC/C/SIC UNIDIRECTIONNEL A ETE ETUDIE EXPERIMENTALEMENT. LES PRINCIPAUX MECANISMES MIS EN JEU ONT ETE IDENTIFIES ET L'INFLUENCE DE PLUSIEURS PARAMETRES A ETE MISE EN EVIDENCE. UN MODELE THEORIQUE PRENANT EN COMPTE LES PHENOMENES DE DIFFUSION ET DE REACTION SIMULTANEE DE L'ESPECE OXYDANTE AVEC LES DIFFERENTS CONSTITUANTS (FIBRE, MATRICE, INTERPHASE) A ETE DEVELOPPE. CE MODELE, QUI PERMET D'ACCEDER A LA CINETIQUE D'OXYDATION DU CARBONE INTERFACIAL, MONTRE LE ROLE DETERMINANT DE L'EPAISSEUR D'INTERPHASE. IL PERMET D'EXPLIQUER QU'A HAUTES TEMPERATURES LES MATERIAUX S'AUTO-PROTEGENT. CE TYPE DE COMPORTEMENT A ETE CONFIRME PAR L'ETUDE DE L'INFLUENCE DE VIEILLISSEMENTS A HAUTES TEMPERATURES SUR LES CARACTERISTIQUES MECANIQUES RESIDUELLES DE CES COMPOSITES

G.HAINNAUX Departement Milieu et Activites Agricoles, Centre ORSTOM, 911 Avenue d' Agropolis, B.P. 5045, 34032 Montpellier Cedex , France. Solid state fermentation, popularly abbreviated as SSF, is currently investigated by many groups throughout the world. The study of this technique was largely neglected in the past in European and Western countries and there is now a high demand for SSF, meaning in food, environment, agricultural, phannaceutical and many other biotechnological applications. It gives me satisfaction to note that the importance of this technique was realised at my department way back in 1975 since then, our team has put concentrated efforts on developing this technique. xvii Foreword Advances in Solid State Fermentation Foreword M. PUYGRENIER Agropolis Valorisation, Avenue d' Agropolis, 34394 Montpellier Cedex 5, France. On the name of the Scientific Community, I would like to express the wish that this International Symposium on SSF should be successful. Solid State Fermentation is part of biotechnology research. It consists on seeding solid culture medium with bacteria or fungi (filamentous or higher) and on producing, in this medium (solid components and exudates) metabolites and high value products. In fact, this process is very old. In older industries such the food and agricultural, this technique has been extensively used. An example of this is the production of pork sausages and Roquefort cheese. Pharmaceutical industry could make extensive use of SSF in the production of secondary metabolites of many kinds and development in this direction is soon expected.
