CONNECTION OF SHEETS OF METAL COMPOSITES AND METHOD TO THIS END Russian patent published in 2015 - IPC B32B15/08 

FIELD: process engineering.

SUBSTANCE: invention relates to permanent joints of sheet structures and parts from composites, primarily, of laminar metal composites and can be used in aerospace engineering, car construction, ship building, etc. Joint of sheets parts from mutual composites comprises outer cover metal sheets and inner alternating metal sheets and composite plies including edges of sheet parts. Note here that edges of cover metal sheets are welded together. Edges of sheets parts on the side opposite said cover metal sheets welded together are made with one-fourth-depth recesses to welded cover metal sheets. Said weld is provided, on one side, with strap connecting the sheet parts edged and fitted with the help of screws screwed in inner metal sheets of edges being connected. Note here that said strap features tee-section in cross-section and is fitted by its rib in edge cutouts filling them without clearance.

EFFECT: sealed permanent joint of metal composites with higher mechanical properties.
