Abstract

L'invention concerne un procédé de fabrication (10) d'au moins une éprouvette à plusieurs couches céramiques pour essai de compression uniaxiale, à chaud, au cours duquel des efforts de compression, globalement parallèles aux couches céramiques de l'éprouvette, sont appliqués, le procédé comprenant : - une étape (11) de réalisation d'un ou plusieurs modèles en matériau éliminable par décirage, présentant une forme de cylindre de révolution s'étendant suivant un axe longitudinal, - une étape (12) de réalisation d'une couche céramique initiale par trempage dans une barbotine comprenant des particules céramiques, dépôt de particules de sable sur la couche ainsi formée par trempage, puis séchage, - au moins une étape (13) de réalisation d'une couche céramique supplémentaire par trempage dans une barbotine comprenant des particules céramiques, dépôt de particules de sable, puis séchage, - une étape (14) de décirage du ou des modèles.The invention relates to a method of manufacturing (10) at least one specimen with several ceramic layers for uniaxial hot compression testing, during which compressive forces, generally parallel to the ceramic layers of the specimen, are applied. , the method comprising: - a step (11) of producing one or more models in material that can be removed by dewaxing, having the shape of a cylinder of revolution extending along a longitudinal axis, - a step (12) of producing an initial ceramic layer by dipping in a slip comprising ceramic particles, depositing sand particles on the layer thus formed by dipping, then drying, - at least one step (13) of producing an additional ceramic layer by dipping in a slip comprising ceramic particles, deposit of sand particles, then drying, - a step (14) of dewaxing the model (s).
