FIELD: process engineering.
SUBSTANCE: invention relates to rods from composites by pultrusion and can be used for production of reinforcement rods. Proposed process comprises impregnation of fibres of roving with binder, forming the bundle from fibres, forming of bonding elements and bundles compaction. Then, performed are heat treatment with polymerisation and cooling at displacing of produced rod by draw device. Note here that making of bundle from fibres, bonding elements on bundle surface and bundle compacting are premade in accumulator by forming of out-of-round profile from bundle fibres. Thereafter, said profile is twisted from the accumulator side by spinning of obtained rod around the axis by draw device.
EFFECT: higher reliability of produced articles.
