LAMELLAR SHEATHING Russian patent published in 2005 - IPC

FIELD: mechanical engineering; production of constructions made out of composite materials of high-precision hardware products of space and land application.

SUBSTANCE: the invention is pertaining to the field of mechanical engineering, in particular, to production of constructions made out of composite materials for the high-precision hardware products of space and land designation, for example, conical nose cones of rocket carriers, transient bays, ring ramps. The lamellar sheathing is made out of layers of the fibrous material impregnated with a polymeric binding. Its each layer represents an unrolling or a part of a cone unrolling made in the form of a sector of a ring or a sector of a circle with a central angle β. In the capacity of the unidirectional fibrous material use a fibrous material impregnated with a polymeric binding. The central angle β of a sector of a ring or a sector of a circle makes 12-360 degrees. Each of layers of the lamellar sheathing consists of the placed butted to each other sectors with the equal central angle γ making 1-30 degrees. In each sector of one layer the fibers of the unidirectional fibrous material are located at the similar for this layer angle φ to the central axis of the sector equal to 0- ±90 degrees. The butts of the sectors of each subsequent layer are shifted in respect to the butts of the sectors of the previous layer at an angle δ composing a part of the central angle γ of the sector for. The technical result of the invention realization consists in creation of the sheathing with the stable physical-mechanical properties.

EFFECT: the invention ensures creation of the sheathing with the stable physical-mechanical properties.
