Extruded molds and methods for manufacturing composite structures using the extruded molds are disclosed. The molds may include recessed or raised longitudinal features to impart a corresponding shape to the molded composite structures. The composite structures may be panels used to construct cargo vehicles, for example.

A zero-Poisson-ratio honeycomb structure and an interlocking assembly manufacturing method thereof are provided, and belong to the field of light structure design and manufacturing. The honeycomb structure is formed by combining a four-pointed star shaped structure and horizontal and vertical honeycomb wall arrays at star corners. The zero-Poisson-ratio honeycomb structure not only has the zero-Poisson-ratio characteristic, but also can achieve respective design of in-plane and out-of-plane mechanical properties. Meanwhile, due to the existence of the horizontal honeycomb walls and the vertical honeycomb walls, the connection of multiple honeycomb walls at angular points in the honeycomb structure is avoided. Moreover, a novel manufacturing mode is provided for the honeycomb structure in addition to prepare the honeycomb structure by utilizing a 3D printing process. The honeycomb structure can be manufactured by combining an interlocking assembly process with resin matrix composites. The performance of the honeycomb structure is further improved at the material level.

Method for determining a manufacturing parameter for making an aligner with a desired aligner thickness using a thermoforming device operable for making the aligner by shaping a precursor aligner into the aligner using a mold representative of a dental archform, the method comprising: obtaining a 3D map associated with the dental archform; parsing the 3D map to determine a first property value and a second property value, the first property value being based on the 3D map and the second property value being derived from a 2D projection of the 3D map, and determining a thickness of the precursor aligner for obtaining the desired aligner thickness based on a ratio of the first property value and the second property value and a given value of an operating parameter of the thermoforming device; and sending instructions to the thermoforming device to make the desired aligner based on the determined operating parameter.

A caul for debulking a composite part broadly includes opposing first and second surfaces, a plurality of through-holes, and a coating. The first surface may have a curvature complementary to a shape of the composite part. The through-holes pass through the caul from the first surface to the second surface. The coating may be a chemically inert material to ensure the caul does not affect the composite part. The caul is configured to be positioned against the composite part for debulking. The caul may be made out of silicone rubber or any other suitable material and may be reusable.

A tooling element includes a flexible sleeve defining an interior cavity. The flexible sleeve includes a sealable access port extending through the flexible sleeve from the interior cavity to an exterior of the flexible sleeve. The tooling element further includes vacuum-packed tooling particulate disposed within and filling the interior cavity of the flexible sleeve.

There are provided a master and a method for manufacturing the master, the master having, on its outer peripheral surface, a concave-convex structure in which concavities or convexities are continuously arranged with high precision. The master includes: a substrate with a hollow cylindrical shape or cylindrical shape; and a concave-convex structure on an outer peripheral surface of the substrate. The concave-convex structure has concavities or convexities continuously arranged at a predetermined pitch in a circumferential direction of the substrate. The concavities or convexities are arranged with a predetermined phase difference between circumferential rows adjacent in an axial direction of the substrate.
