STRUCTURES CONNECTION ASSEMBLY FROM COMPOSITE MATERIALS Russian patent published in 2016 - IPC B29C70/86 

FIELD: machine building.

SUBSTANCE: invention relates to high-load structures from polymer composite materials and can be used in aircraft engineering and space equipment, as well as in ship building, etc. Structures connection assembly from composite materials comprises a reinforcing element consisting of a core and a shell made from spatially-reinforced material and having a triangular shape with flat base and two arc-shaped sides. Core is made as a lengthwise element billet with trapezoidal cross-section from adhesive film layers overlaid on each other. Spatially-reinforced material of the shell in the base area includes fibres along the longitudinal axis of the reinforcing element.

EFFECT: simple and cheap creation of composite materials connection assembly by prepreg technology, as well as high strength of the assembly structure are achieved.
