METHOD FOR MANUFACTURING SECTIONS OF THREE-LAYER STRUCTURE FROM POLYMER COMPOSITE MATERIALS Russian patent published in 2018 - IPC B63B5/24 B29C65/48 

FIELD: shipbuilding.

SUBSTANCE: invention relates to plastic shipbuilding and can be used in the manufacture of sections of bulkheads, fences, cabin walls and superstructures of a three-layer structure made of polymer composite materials (PCM). Method is proposed for manufacturing sections of a three-layer PCM structure comprising manufacturing a middle layer of the three-layer structure of individual panels consisting of trapezoidal or U-shaped stiffening ribs joined into a single corrugated element filled with polystyrene from both sides to flush flanges, interconnecting the panels by width and by length of the sections along the generatrix of the corrugated element followed by molding of one bearing layer and after reversing the section of the second bearing PCM layer. Interconnecting the middle layer panels by length of the sections is carried out with rectangular inserts made in advance from PCM, which are pasted into pre-cut slots between the walls of the corrugations and the foam with the use of an adhesive composition.

EFFECT: technical result is reducing the labor intensity and reducing the time for manufacturing the sections.
