METHOD OF MAKING COMPOSITE ROD Russian patent published in 2024 - IPC B29C53/14 E04C5/07 D07B3/06 

FIELD: various technological processes.

SUBSTANCE: invention relates to a method of producing a non-metallic composite rod. Technical result is achieved by a method for manufacturing a composite rod, which includes drawing, impregnation with a binder, forming a composite rod barrel from a core and an outer layer, high-temperature polymerization, cooling and cutting. At that, the core is formed by means of the device placed in front of the bobbins or on the same line with them and representing a rotatable drum, on which flywheels are installed with possibility of rotation with at least two coils fixed on each of them and made with possibility of rotation. When the flywheels are rotated, the roving threads from the coils are woven into bundles, and when the drum rotates, the bundles are intertwined to form a core. Straight roving threads are drawn from the bobbins through the binder impregnation unit, and the core is drawn over the container with the binder, then the core flows are drawn through a die or a periodic profile application device, where by means of compression around the core the outer layer of several layers of straight threads is formed. During compression, part of the binder penetrates inside the core, thus forming a solid barrel-workpiece, after which the solid barrel-workpiece enters the polymerisation chamber.

EFFECT: improved strength characteristics of the composite rod for axial tension, fracture and bending.
