Thrust reverser cascade for an aircraft nacelle

A thrust reverser cascade for an aircraft nacelle includes a plurality of blades having a first and a second surface, the blades being connected to members connected to attachment flanges for attaching the thrust reverser cascade to the nacelle. At least one of the surfaces of the blades is covered with at least one layer of fibers, each layer including a plurality of fiber pieces which are pre-impregnated with resin. The fiber pieces are superimposed on one another, positioned parallel to the aerodynamic surface of the blade and oriented in different directions.

Physical reutilization of siliconized sheets

The method for the physical reutilization of sheet-like siliconized structures comprises treating the sheet-like siliconized structure in a liquid digestion system comprising acetic anhydride and/or an acetoxysiloxane, and at least one Brønsted acid, optionally solvent, preferably with addition of acetic acid, and removing the desiliconized sheet-like structure from the liquid phase.

Process for the production of an additive for bituminous conglomerates with high mechanical performances

The present invention refers to a process for the production of an additive composition intended to be mixed into a bituminous conglomerate for road paving. The process includes grinding a mixed waste material containing a mixture of plastic materials, which includes at least one plastic material based on a polyolefin thermoplastic material, washing the ground mixed waste material and separating a portion of low-density material which contains the plastic material based on a polyolefin thermoplastic polymer from the mixed waste material. This portion of low-density material is then ground to a particle size between 10 mm and 20 mm; and then mixed with a material based on polyvinyl butyral. The resultant mixture is further ground to produce an additive composition having a particle size between 4 mm and 6 mm.

Contour-forming welding tool for pulse welding and contour-forming pulse welding method for a medical pack formed as a bag

The invention relates to a welding tool and to a method for pulse welding of plastic films for medical packs formed as bags. In general, the invention provides that the film material which is plastified during welding and thus free-flowing is specifically displaced into a deepened, edge-side inner region of the sealing surface by increasing the sealing surface area. The film material accumulated in the recess leads to an increase in the film thickness in the inner region (25i) of the weld seam (6, 7, 8). As a result, the mechanical stability of the medical pack formed as a bag can be improved.

METHOD FOR MANUFACTURING FIBER-REINFORCED RESIN STRUCTURE
20230102696 · 2023-03-30 ·

A novel method for producing a fiber-reinforced resin structure is provided, which has excellent strength but can be formed in various shapes. A fiber-reinforced resin structure is manufactured by preparing an assembly including a first foam having a columnar shape, a fiber body covering at least a part of a side surface portion of the first foam, and a second foam having a columnar shape adjacent to the first foam via the fiber body.

FIBER-REINFORCED RESIN MATERIAL, METHOD FOR MANUFACTURING SAME, AND FIBER-REINFORCED RESIN STRUCTURE

The fiber-reinforced resin material of the present invention is a fiber-reinforced resin material having a laminated structure in which fiber assembly layers and thermoplastic resin layers are alternately located, wherein the fiber assembly layers are each an assembly of continuous fibers having thermoplastic resin particles attached to surfaces thereof, and the fiber-reinforced resin material has a higher elongation on one surface side than that on the other surface side. The fiber-reinforced resin structure is made of the present fiber-reinforced resin material. A method for manufacturing the present fiber-reinforced resin material includes: a stacking step of stacking a sheet-shaped product of the continuous fibers that serves as the fiber assembly layer and a resin sheet that serves as the thermoplastic resin layer so as to obtain the laminated structure; and a hot-pressing step of heating and compressing a stacked product obtained through the stacking step in a stacking direction.
