[ What I claim is:] [1.] Structural element which comprises a first piece and at least a second piece wherein at least said first piece comprises a plurality of projections which establish a preform and said second piece comprises a relatively smooth surface and receives said first piece, wherein said projections of said first piece are fixed to said second piece which upon fixing establish a very rigid, resistant to flexure and light weight tridimensional structure, each of said projections of said first piece comprising a base, each of said projections of said first piece being selected from the group consisting of:a. a solid projection; andb. a projection including at least one aperture through at least one of projecting side walls of said projection, all of said bases forming a substantially continuous surface, said first piece and at least said second piece comprising an interior component of said structural element of substantially the same rigidity as at least one layer of said structural element exterior to said interior component, said first piece and at least said second piece comprising said at least one layer of said structural element, said at least one layer of said structural element being substantially rigid.
