摘要： A method for preparing a carbon/boron carbide composite material includes the following steps (A) providing a carbon compound, a carbon fiber, a boron compound and a binder to perform a pretreatment mixing procedure to form a precursor; (B) putting the precursor into a spray granulator for performing a granulation process and mixing the precursor to form an injection material with a uniform composition; (C) feeding the injection material into an injection molding machine for performing a compression molding process, thereby forming a carbon compound/boron compound green body; and (D) subjecting the carbon compound/boron compound green body to a two-stage heat treatment process to obtain the carbon/boron carbide composite material.

摘要： 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.

摘要： A sinterable paste formulation usable as cast material in a cast-mold process, in combination with a mold material formulation, is provided. The sinterable paste formulation comprises a power of a sinterable material, in an amount of at least 85% by weight of the total weight of the formulation, a binder as described in the specification, and an aqueous solution which comprises water and a water-miscible organic solvent featuring an evaporation rate in a range of from 0.3 to 0.8 on an n-butyl acetate scale. Methods employing the formulation and objects and products obtained therefrom are also provided.

摘要： A disclosed method of forming a ceramic article includes forming a pre-ceramic polymer article within a mold tool, and performing a first pyrolizing step on the initial pre-ceramic polymer article to form a ceramic article. The method further includes performing at least one pre-heat treatment polymer infiltration and pyrolizing (PIP) cycle on the ceramic article and an initial heat treatment cycle of the ceramic article after the at least one pre-heat treatment PIP cycle. Subsequent PIP cycles and heat treatment cycles are performed in combination to form a ceramic article including a desired density.

摘要： A method for injecting a loaded suspension into a fibrous texture having a three-dimensional or multilayer weaving includes the injection of a suspension containing a powder of solid particles into the volume of the fibrous texture. The injection of the loaded suspension is carried out by at least one hollow needle in communication with a loaded suspension supply device, each needle being movable in at least one direction extending between a first face and a second opposite face of the fibrous texture so as to inject the loaded suspension at one or more determined depths in the fibrous texture.
