A planar space frame for a unibody panel of a vehicle comprises a core mounted onto the bottom side of a load bearing panel. The core is a 3-D truss including a series of triangular prisms. The triangular prisms have a specific pattern of alternating triangular openings on each of their three lateral faces. For each triangular prism, triangular openings located on the lateral face which is part of a planar layer are alternating right triangles placed two by two to form rectangular units. The right triangles are arranged to have the edges on each side of the right angles aligned with the edges of the planar layer. The triangular openings located on the two inclined lateral faces of each triangular prism, are alternating isosceles triangles placed two by two to form rhomboid units. This combination of triangles provides structural strength and housing functionality.
