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.

The present invention relates to a manufacturing process for a watch component (50) in composite material with a ceramic matrix comprising the following steps: depositing in a mould a succession of layers (10, 20, 30, 40) each comprising a ceramic powder (12), at least one layer (10; 10, 30; 10, 20, 30, 40) further including fibres (14) mixed with the ceramic powder (12), the fibres (14) being arranged randomly; performing a FAST/SPS sintering operation; demoulding the sintered watch component comprising the succession of layers (10, 20, 30, 40), and optionally machining the sintered component to the final dimensions of the watch component (50). The fibres (14) are visible on the surface of the watch component (50).

Disclosed is settlement substrate for oyster technology, and, in particular, the present disclosure relates to a concrete settlement substrate for oyster and a preparation method thereof, and a construction method. The concrete settlement substrate for oyster has the characteristics of induction of rapid settlement and metamorphosis of sessile organisms thereto, promotion of long-term growth and good durability, and the oysters are settled on a surface of concrete. A reasonable spatial layout is utilized, such that each concrete pile (block) can effectively break waves and ensure smooth exchange between water bodies on two sides. After oysters settled to each concrete pile (block) breed a large amount, the water bodies can be purified, and the ecological environment in the surrounding sea area can be improved.
