A composite structure joining system and method comprises a structural panel, preferably but not necessarily fabricated from structural composite materials, that further comprises a nesting C-joint feature that facilitates assembly of a plurality of panels of the invention to form a planar structure such as a wall. An embodiment of the present invention comprises a plurality of the panels of the invention, joined together using the C joint of the invention, captured in a frame. The frame structural elements may comprise metals such as aluminum or steel, or may be hand laid or extruded fiberglass as described in more detail below. The invention further comprises methods of manufacturing a plurality of structural panels of the invention. The method of the invention may be used to fabricate intermodal shipping containers that have superior structural and thermal characteristics, are lightweight, resulting in lower transportation costs and lower container costs.

A morphing panel mechanism may include a central panel and a side panel, where a first edge of the side panel may be pivotally coupled to a first edge of the central panel. A morphing panel mechanism may further include a guide panel that may be coupled with a first corner of the central panel via a ball joint, where the guide panel may include a first slit. A morphing panel mechanism may further include a flexible panel, where a first edge of the flexible panel may be pivotally coupled with a second edge of the side panel, and a second edge of the flexible panel may be slidably disposed within the slit of the guide panel.

Building stud (10) for forming a framework for mounting wall panels, comprising a first (12) and a second (14) flange portion and a web portion (16) interconnecting the flange portions. The flange portions comprise a planar, elongated wood fibre member (18, 20), and the web portion comprises a polymer based and/or cellulose fibre based sheet member (22) including a first (24) and a second (26) rectilinear line of weakness, which lines of weakness are parallel and along which the sheet member is foldable to enable folding the building stud from a retracted storage position to an expanded mounting position.

A set of essentially identical panels, such as building panels, provided with a mechanical locking system including a displaceable tongue, which is arranged in a displacement groove with a first opening at a first edge of a first panel. The displaceable tongue is configured to cooperate with a first tongue groove, with a second opening at a second edge of an adjacent second panel, for vertical locking of the first and the second edge. The height of the first opening is greater than a second height of the second opening.
