METHOD OF LAYERING FOR NON-PLANAR COMPONENTS MADE OF COMPOSITE MATERIAL Russian patent published in 2016 - IPC B32B3/00 

FIELD: materials.

SUBSTANCE: invention relates to a method of layering resin pre-impregnated bands made of composite material and to a non-planar composite component containing band of composite material. Method comprises determining trajectory of bands as modified trajectories of geodesic trajectories. Projecting geodesic trajectories corresponding to bands on horizontal plane. Modifying horizontal projection trajectories to satisfy following conditions of their projections on horizontal plane. Radius R₂ of curvature of their curvilinear segments is greater than specified value R_min. Gap G_2p between two adjacent bands varies from 0 to a given value G_max. Obtaining modified trajectories on corresponding surfaces of layering by crossing said surfaces with vertical plane, which comprises modified horizontal trajectories. Outputting modified trajectories into ATL machine for application of layers.

EFFECT: higher quality of finished articles.
