COMPOSITE REINFORCING ELEMENT FOR HIGH RESISTANCE TO COMPOSITE STRINGER RETRACTION Russian patent published in 2015 - IPC B29C70/34 

FIELD: transport.

SUBSTANCE: invention to aircraft engineering, particularly, to aircraft structural elements made of composites. Claimed device comprises long composite element, channel and multiple composite structures. Said long composite element has the side to be coupled with the structure surface. Aforesaid channel is located on one side to extend over the long composite element length. Said multiple composite structures can be arranged in said channel to secure the long composite element side section at said structure. Composite structure of multiple composite structures contains the plies of different orientation selected for increase in the long composite element in resistance to its retraction from the structure.

EFFECT: higher physical and mechanical properties of articles.
