A construction element includes at least one module with a rectangular parallelepiped shape, hollow and made of a composite material. The module is delimited by an enclosure with four panels, two first opposing parallel panels and two second panels perpendicular to the first panels. The second panels include at least one groove parallel to the first panels. Each second panel is extended on one side by an L-shaped profile and on the other side by a flat profile. The profiles are elements protruding outwards, parallel to the groove.

There is provided herein a modular be fabricated wall system which has a number of interlocking modular prefabricated wall sections. Each wall section has opposing planar face boards and a number of orthogonal spacers adhered to respective inner faces of the face boards for bracing the face boards apart. Vertical joiners may be adhered to inner edges of each face board for quickly and easily vertically slotting together adjacent wall sections in a row. The present wall sections are low-cost in that both the face boards and the orthogonal spacers may be cut from low-cost board, such as fibre cement board. Specifically, the face boards and the spacers may be both made from fibre cement board and the spacers may be glued perpendicularly between inner surfaces of the face boards. As such, the present wall sections may be manufactured without fasteners, ties and the like.

A panel structure and a method of forming the panel structure are disclosed. The panel structure typically includes at least one panel associated with a material. The panel structure has been found particularly advantageous for use as an interior panel of an airplane.

Acoustic structures in which acoustic septa are located in the cells of a honeycomb for reducing the noise generated from a source. The honeycomb used to form the acoustic structure has walls that contain convex and concave contours which make the honeycomb flexible. The acoustic septa are formed by inserting planar acoustic inserts into the honeycomb cells to form a septum cap which is friction-locked within the cell and then permanently bonded in place. The planar acoustic septum is configured to match the unique shape of the cell contours to provide desired friction-locking when inserted into the cells and desired acoustic properties after being permanently bonded in place.

A composite panel for use in applications such as mobile homes, boats, busses, 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 panel assembly can include a first panel having a peripheral side located between an upper and a lower surface of the first panel and a first opening. The panel assembly can also include a second panel having a second opening. An elongated insert can be coupled to the first panel, the elongated insert having a coupling side, where the first opening of the first panel can be sized and shaped to coupleably receive the elongated insert such that the coupling side is positioned proximal to the peripheral side. The panel assembly can also include a fastening insert, where the second opening of the second panel can be sized and shaped to receive the fastening insert. A fastener can be received by the fastening insert and the elongated insert, the fastener coupling the first panel to the second panel via the fastening insert and the elongated insert. Related methods for assembling the panel assembly are also provided.

A structural flooring panel comprises an upper sheet, a lower sheet and a plurality of longitudinally extending ribs between the sheets. The ribs are laterally spaced to define at least one longitudinally extending, internal channel within the panel.

The present invention provides a sandwich panel and a sandwich panel structure formed by welding a plurality of the sandwich panels, each sandwich panel comprising: a flocking core layer; and skin layers laminated on both surfaces of the flocking core layer, respectively, wherein the sandwich panel comprises at least one contact portion, at which the two skin layers abut each other. In addition, the present disclosure provides a method for manufacturing a sandwich panel, the method comprising the steps of: preparing a sandwich panel comprising a flocking core layer and skin layers laminated on both surfaces of the flocking core layer, respectively; and applying heat and pressure to at least one surface of the skin layers, thereby forming at least one contact portion.
