Abstract

Un procédé de fabrication d'un bol monobloc en matériau composite thermostructural formé d'un renfort fibreux densifié par une matrice qui comprend la fourniture de strates fibreuses déformables en un seul tenant exemptes de fentes ou de découpes, la superposition desdites strates sur une forme correspondant au bol à réaliser, en les déformant, et la liaison des strates superposées entre elles au moyen de fibres s'étendant transversalement par rapport aux strates, par exemple par aiguilletage de manière à obtenir une préforme de bol qui est ensuite densifiée. Le bol (1) est utilisable comme support de creuset (5) dans une installation de production de silicium monocristallin.
