A system and method for authenticating a physical object. The method may include the steps of: (1) encoding a feed material with randomized information; (2) forming the object with the feed material such that one or more portions of the object have respective randomized signatures based upon at least some of the randomized information of the feed material; (3) reading the respective randomized signatures at the one or portions of the object; (4) creating a profile of the respective randomized signatures at the one or more portions of the object based upon information from the reading; (5) transporting the physical object to an authenticator, and transmitting the profile to the authenticator; (6) reading the respective randomized signatures at the one or more portions of the object by the authenticator; and (7) comparing the reading by the authenticator to the profile received by the authenticator to thereby authenticate the physical object.

Described are methods and systems for identifying processing locations in composite layups. An optical magnetic marker is magnetically supported by a layup tool at a target position, such that a portion of the marker protrudes above the tool processing surface. When a composite layup is placed onto that surface, the protruding portion extends into the layup at a processing location. When the layup is cured, the marker is permanently embedded into the layup. Separating the cured layup from the tool removes the marker from the tool and allows an additional marker to advance into the target position for processing another layup. The embedded marker or, more specifically, marker's reflective surface is used during optical inspection of the layup surface to precisely determine the processing location. In some examples, the marker is consumed while the layup is processed at that location,

The invention relates to a lightweight, mass-producible, antibacterial insulation material with high heat, corrosion and impact resistance that can be used in construction, machinery & equipment, furniture, defense, apparel-accessory industry, art, as well as in land-sea-air vehicles.

The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a nonwoven facing and to methods for making such panels. One aspect of the disclosure is a method for preparing an acoustic panel comprising providing a base structure. The base structure has one or more edges, an outward major surface having a total are, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The method includes disposing directly against the outward major surface of the base structure a sprayable mixture comprising a plurality of fibers, one or more binders, and a dispersive medium. The method includes drying the disposed mixture to provide a facing layer disposed on the outward major surface of the base structure, the facing layer having an exterior major surface opposing the outward major surface of the base structure.

A fiber composite structure includes a base structure being formed of a first fiber composite material that includes first fiber bundles embedded in a first matrix material, wherein the base structure includes an opening defined by first fiber bundles which include first sections and a second section that continuously or uninterruptedly interconnects the first sections, wherein the second section forms a bay that defines a part of the circumference of the opening. The fiber composite structure further includes a functional structure positioned in the opening of the base structure and joined with the first fiber composite material of the base structure.

A composite structure is disclosed forming part of a wall of a liquid hydrogen tank, and including at least one thermal protection device having one or more of hollow fibers, such as to create thermal protection, for example a thermal barrier or a heat exchanger, which makes it possible to protect the composite structure in case of a high temperature gradient between the two faces thereof, while benefiting from the advantages of a composite material in terms of mass.
