A process for manufacturing a composite material part includes formation of a fibrous texture from refractory ceramic fibres, placement of the fibrous texture in a mould with interposition of a filtration layer between the fibrous texture and a discharge port, the filtration layer including a partially densified fibrous structure, pressure injection of a slurry containing a powder of refractory ceramic particles into the fibrous texture, drainage by the filtration layer of the slurry solvent having passed through the fibrous texture and retention of the powder of refractory ceramic particles within the texture by the filtration layer to obtain a fibrous preform including the fibrous texture filled with refractory ceramic particles and the filtration layer, heat treatment of the refractory ceramic particles present in the fibrous texture of the preform to form a composite material part including the fibrous texture densified by a refractory ceramic matrix and the filtration layer.

A block reinforcement cage made from reinforcing material and adapted for loading within a machine during a block manufacturing process for molding a concrete U-wall construction block structure. The block cage includes an open aperture formed in each of its stem reinforcing portions. During the block manufacturing process, the first and second support members of a support mechanism are inserted within the open apertures formed in the stem reinforcing sections of the block cage, and cooperate with the open apertures of the block cage so as to (i) support the block cage when being loaded into a block manufacturing machine, (ii) define central apertures molded in each stem portion of the concrete U-wall construction block structure, and (iii) lift the molded concrete U-wall construction block when being unloaded from the machine.

A machine for and method of manufacturing concrete U-wall type construction blocks by molding each concrete u-wall construction block from concrete poured about a block cage made from reinforcing material while said block cage is loaded within the machine. The method involves providing a system of molding jacket panels, including a core molding assembly having a pair of inside stem jacket panels that are adjustably supportable in a substantially parallel manner during a molding process, and arranged is such a manner that the front wall portion is molded in downwardly facing direction toward a horizontal support surface and completely enclosed in one or more molding jacket panels. Before block molding operations, the thickness of the front wall portion of the U-wall construction block is set by determining the thickness of a front wall surface liner and installing the front wall surface forming liner within the system of molding jacket panels.

A mold for producing an article of manufacture from a mixture comprising liquid, said mold comprising: a pressing layer having a pressing layer front surface configured to press the mixture and extract the liquid therefrom, and an opposite pressing layer back surface a backing plate having a backing plate front surface facing the pressing layer back surface and an opposite backing plate back surface; and a liquid accumulating space extending at least partially in a plane parallel to the pressing layer and positioned between the backing plate back surface and the pressing layer front surface, the liquid accumulating space being configured to accumulate the liquid therein.
