Method for producing a double-walled thermostructural monolithic composite part, and part produced

A fibrous preform (1) is produced, provided with a sandwich structure comprising an intermediate flexible core (4) and two outer fibrous frames (2, 3), respectively arranged on opposing outer faces of said flexible core (4) and assembled by sections of wire (8, 9) passing through said fibrous frames (2, 3), said preform (1) being impregnated with resin. Said preform is then hardened and the core (4) is removed, preferably by pre-densification with chemical vapour infiltration, and the structure produced is then densified with liquid-phase infiltration.

Surgeon gown with sealed sleeves and methods of manufacturing the same

A medical gown (701) includes a layer of material (100) with a seam (401) disposed across the layer of material. The material can include a weave (110) of untwisted, continuous filament polyester. The material can also include a carbon filament (109). The seam is sealed by applying a tape (200) across the seam and applying heat to cause the tape to attach to the weave.

Adhesive fabrication process for garments and other fabric products
10750805 · 2020-08-25 · ·

A process for fabricating a three-dimensional, multi-layered fabric product with a moisture barrier is provided. A partially seamed inner lining fabric assembly having at least a two-dimensional shape is laminated with a membrane barrier film having flaps left un-laminated to cover at least one seam. The inner lining fabric assembly is further seamed and flaps of the of the membrane barrier film overlapped into contact with each other and sealed to provide a continuous moisture barrier. A process for fabricating a stretchable section of a garment with a moisture barrier is also provided. At least a section of a garment is formed from fibers arranged in a pattern having a direction of stretch in one direction and a three-dimensional surface texture such that a portion of the fibers protrude above another portion of the fibers. The stretchable section is stretched in the direction of stretch. Segments of a membrane barrier film are adhered to an outer edge of the protruding portion of the fibers while the section is stretched in the direction of stretch, leaving intermediate segments of the barrier film free from adherence to the section. In this way, the intermediate segments of the membrane barrier film include slack that folds up to form ruches when the section is in a relaxed state.
