FIELD: process engineering.SUBSTANCE: invention relates to production of sections from fibrous composite material to be used in aircraft and aerospace engineering. Proposed method comprises the following steps. First, workpiece made from, in particular, impregnated fibrous material is packed in vacuum bag. Then, workpiece support elements are placed thereon. Then, vacuum is created in said bag. Now, workpiece is hardened by heat, in particular, in autoclave for making the section. In compliance with this invention, aforesaid support elements are, preferably, made from aluminium instead of expensive steel H36 since said elements are mechanically separated by vacuum bag from workpiece along lengthwise axis that allows displacement of support elements there along relative to work piece.EFFECT: higher efficiency.3 cl, 4 dwg |
