PROCESS FOR MANUFACTURING A TEST WITH MULTIPLE CERAMIC LAYERS, TEST TUBE OBTAINED BY IMPLEMENTING SUCH A PROCESS OF MANUFACTURE AND USE OF SUCH A TEST FOR A UNIAXIAL COMPRESSION HOT TEST

摘要

The invention relates to a method for manufacturing (10) at least one test tube with several ceramic layers for uniaxial compression testing, in the heat, during which compression forces, generally parallel to the ceramic layers of the test piece, are applied. , the method comprising: - a step (11) of producing one or more models of material which can be removed by dewaxing, having a shape of cylinder of revolution extending along a longitudinal axis, - a step (12) of producing an initial ceramic layer by soaking in a slip comprising ceramic particles, depositing sand particles on the layer thus formed by soaking, then drying, - at least one step (13) of producing an additional ceramic layer by soaking in a slip comprising ceramic particles, depositing sand particles, then drying, - a step (14) of dewaxing the model or models.
