Abstract
A space truss composite panel is excellent in structural mechanics and capable of being efficiently and economically produced. The space truss composite panel has a construction in which a sheet 1 provided with a series of slits 2 is formed into a space framework 3 through a press working. The space framework 3 is provided with a series of polygonal unit lattices in one of its opposite sides and a series of polygonal pyramids in the other of the opposite sides, wherein each of the polygonal unit lattices has an intersection of its adjacent sides 3a, 3a connected with a ridgeline portion 3b of each of the polygonal pyramids, and the space framework 3 has at least one of its opposite sides connected with a board-like member 4.
