The non-metallic cloth (3) has a large number of fibers (6) in two parallel groups crossing each other at an acute angle. The angle near the edge of the sheet (alpha), plus or minus 30 degrees, is smaller than the angle (beta), plus or minus 45 degrees, away from the edge. The fiber angle changes in a curved region (9) between the edge and the main body of the sheet. An adhesive strip (5) fastens the edge of the sheet on the flange (4) on the hollow profile beam (2) forming part of the bodywork structure (1). |
