METHOD OF PRODUCING STRUCTURAL PARTS FROM COMPOSITE MATERIALS AND WINDOW COMPOSITE RING THUS PRODUCED Russian patent published in 2013 - IPC B32B5/12 B29B11/16 B29C63/22 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building, particularly to production of structural parts from composite materials. Window composite ring with multilayer reinforcing material has ring-shape closed contour and nonstandard profile. It comprises inner and outer flanges and ribs made from laid textile reinforcing materials bent from flange into rib and embedded into stiff polymer binder. Ring layers are made up of braided and woven hose-shaped clothes with diagonal braiding of threads. Layering is performed by horse-shaped cloth bending over inner and outer edges of flanges and rib so that every next layer makes an extension of previous layer to allow a smooth continuous seamless transition of layers from flanges to rib and vice versa.

EFFECT: lower labour input and costs.
