A honeycomb-like core member that can be easily manufactured is disclosed, and a structure using such core member is disclosed. The core member has a plurality of flat plate members (a plurality of first flat plates and a plurality of second flat plates), each of which includes a comb teeth portion that has a plurality of notches, which are open in the long side of a rectangular shape of the flat plate member and extend parallel to the short side of the rectangular shape of the flat plate member. The notches are engaged with each other so that the plate members cross each other, and thus, a plurality of hexagonal-cylinder-shaped first cylinder portions and a plurality of triangular-cylinder-shaped second cylinder portions are formed by the plate members.

Disclosed is a method for forming a hollow pipe-sandwiching metal plate and applications thereof. The hollow pipe-sandwiching metal plate comprises a first panel, a second panel, and multiple hollow pipes between the first panel and the second panel; gaps are arranged among the hollow pipes, and the hollow pipes are connected to the first panel and the second panel by brazing. The present disclosure further includes the applications of the hollow pipe-sandwiching metal plate. The hollow pipe-sandwiching metal plate has advantages, such as light weight, high strength, low stress, high temperature resistance, pressure bearing, thermal insulation and vibration isolation. The metal plate will not deform due to thermal difference, thereby providing permanent service life of the metal plate.

A surface panel is disclosed, the panel comprising two planar members in parallel spaced arrangement and being joined together by a plurality of mutually parallel tubular cells. Each tubular cell defines with the planar members an isolated cell volume. A tubular cell wall can be contiguously arranged with a neighbouring cell and also share a dividing wall with said cell.

Preferably a tubular cell has a hexagonal shape with the cells forming a honeycomb array. A planar member optionally comprises a surface which further comprises a plurality of ribs arranged in a hexagonal configuration, with the diameter of each said hexagonal tubular cell being larger than the diameter of each said hexagonal rib configuration of said first planar member.

The present invention provides layered panel that comprises a filler insert, a dense frame and a bond frame having at least one rectangular dense frame opening, a first external layer having a rectangular shape and a flat surface, and a second external layer.

A device for securing goods (1) to be transported onto a load carrier (2), in particular a pallet (2), having a rod-shaped fastening element (3), which can be fastened to the load carrier (2), and a retaining element (4) for engaging with the goods (1) to be transported, said retaining element cooperating with the fastening element (3), is designed and developed, with regard to secure fastening of goods to be transported with universal usability and ease of handling, in such a way that a thread (5) for fastening to the load carrier (2) is formed at an end of the fastening element (3).

A vented honeycomb structure with a plurality of honeycomb cells arranged in a hierarchical order and having a plurality of truss walls, each truss wall including a plurality of members. The vented honeycomb structure is fabricated by joining a plurality of sheets of trusses using any one of an expansion, a corrugation, and a slotting process. Fabrication can also occur by deposition, casting, additive, extrusion, or aligning and joining methods. The honeycomb cells, truss walls, truss wall openings, and truss wall members can be functionally graded.

A residential or commercial building, structure, or building component can include an exterior member, interior member, and plurality of cross-members spatially disposed therebetween. Each of the exterior member, interior member, cross-members can be formed from a multi-layered stack of polymeric material made by a layered three-dimensional printing process, and all can be monolithically integrated. An exterior surface region of the exterior member can have an integrally formed surface finish. Overlying finishing or connective layers can be added. The exterior and interior members can be configured in a parallel arrangement to form a rectangular or curve shaped building block. A fill material can be disposed into openings between the exterior and interior members, and an interior surface region at the interior member can include a cavity configured for an electrical box, plumbing, or a sensing device.

A render layer for a building comprises a honeycomb core of nonwoven polypropylene web, and a cementitious material fully filling the cells of the core, wherein (i) the nonwoven web has a porosity of from 5 microns to 600 microns, (ii) the core has a cell size of from 5 mm to 200 mm, (iii) the expansion and contraction across the plane of the core is greater than the expansion and contraction of the cementitious material filling the cells of the core, and (iv) the cementitious material is partly impregnated into the cell walls of the core.

Methods and apparatus to couple a decorative layer to a panel via a high-bond adhesive layer are disclosed. An example apparatus includes a panel, a high-bond adhesive layer fixed to the panel, a liner fixed to the high-bond adhesive layer that is fixed to the panel, and a first decorative layer removably coupled to the liner that is fixed to the high-bond adhesive layer via a second adhesive layer. The high-bond adhesive layer is to impede at least one of gas or vapor from escaping the panel to deter the at least one of gas or vapor from exerting a pressure on the first decorative layer to deter a portion of the first decorative layer from separating from the panel.

The disclosure relates to additively manufactured (AM) composite structures such as panels for use in transport structures or other mechanized assemblies. An AM core may be optimized for an intended application of a panel. In various embodiments, one or more values such as strength, stiffness, density, energy absorption, ductility, etc. may be optimized in a single AM core to vary across the AM core in one or more directions for supporting expected load conditions. In an embodiment, the expected load conditions may include forces applied to the AM core or corresponding panel from different directions in up to three dimensions. Where the structure is a panel, face sheets may be affixed to respective sides of the core. The AM core may be a custom honeycomb structure. In other embodiments, the face sheets may have custom 3-D profiles formed traditionally or through additive manufacturing to enable structural panels with complex profiles. The AM core may include a protrusion to provide fixturing features to enable external connections. In other embodiments, inserts, fasteners, or internal channels may be co-printed with the core. In still other embodiments, the AM core may be used in a composite structure such as, for example a rotor blade or a vehicle component.
