A one-piece component comprising a tetrahedral-octahedral honeycomb lattice is disclosed herein, along with a mold, a system and methods of making the component. A one-piece component comprising a truncated tetrahedral-octahedral honeycomb lattice also is disclosed, along with corresponding molds, systems and methods.

An insulation product may include a container, a first insulation material forming a first layer inside the container, and a second insulation material forming a second layer inside the container, and the first layer is compressed by the second layer. A structure in a building may include studs, first and second claddings mounted to opposite sides of the studs, and structure spaces defined between the studs and the opposing claddings. A first insulation material may include first layers on and substantially covering a first one of the claddings inside the structure spaces. In addition, a second insulation material may have second layers inside the structure spaces. The first layers are compressed and substantially covered by the second layers, and the second layers substantially cover a second one of the claddings inside the structure spaces.

A composite panel for use in applications such as mobile homes, boats, buses, RVs, or other panels used typically in transportation applications, where a single piece, water resistant, lightweight panel with patterned high-strength areas is needed. The composite panel generally includes internal preforms made of low-density material such as urethane foam, which create patterned structural portions of the panel during the molding process. The patterned structural portions are formed by a maze-like region within a mold, into which composite matrix material is infused. The patterned structural portions have high strength compared to the other regions of the panel, and can be used for structural support or for retaining fasteners for appliances, walls, etc.

A system and a method for securing a first composite panel to a second composite panel include a latch assembly having one or more latches. The latch assembly is configured to be secured to one of the first composite panel or the second composite panel. One or more strikes are configured to retain at least a portion of the one or more latches. The one or more strikes are configured to be secured to the other of the first composite panel or the second composite panel.

The present disclosure relates to a hollow board 1 with first and second main surface layers 3, 5. A plurality of distance elements connecting the first and second main surface layers and maintain a predetermined distance there between. The main surface layers include at least a layer of high-density fiber, HDF, board, and a plurality of distance elements are distributed in the space between the main surface layers, and at least some comprise at least one elongate HDF board strip 15 which is oriented such that its longitudinal edges interconnect the first and second main surface layers 3, 5. The HDF boards of the surface layers and of the at least some of the distance elements comprise wood particles bonded by a resin including an isocyanate, such as methylene diphenyl di-isocyanate, MDI.

An acoustic panel (for absorbing sound) includes a first sheet with spaced microperforations, a second sheet with microperforations more widely spaced than the microperforations of the first sheet, and a first cellular core sandwiched between the first sheet and the second sheet. The panel can be spaced from a surface, such as a wall. A second cellular core can be provided between the second sheet and a third sheet. The third sheet is preferably solid without microperforations but can have microperforations. Noise Reduction Coefficient (NRC) can be 0.8.
