Abstract
A manufacturing method for a composite material part includes injecting under pressure a slip containing a refractory ceramic particle powder into the moulding cavity of an injection tooling, draining the liquid from the slip that passed through the moulding cavity and retaining the particle powder inside the moulding cavity to obtain a blank including refractory particles, demoulding the blank, and heat treating the blank to form a part. The injection tooling includes a porous material mould consisting of a moulding cavity, an enclosure of rigid material in which the porous material mould is held, the enclosure further including an injection port, a discharge vent and an injection canal connecting the injection port to the moulding cavity of the porous mould for the injection of the slip into the moulding cavity. The injection tooling includes a sacrificial capsule of porous material placed in moulding cavity.
