METHOD FOR PRODUCING A SEMI-RIGID HARNESS BASED ON CARBON FIBER AND SUPER ENGINEERING PLASTICS IN ONE STAGE OF IMPREGNATION FOR 3D PRINTING BY FUSED DEPOSITION MODELLING METHOD Russian patent published in 2023 - IPC B29B15/14 B29C64/106 B29C70/34 B33Y40/00 

FIELD: 3D printing.

SUBSTANCE: invention relates to the field of three-dimensional printing, namely, to a method for producing a semi-rigid bundle based on carbon fiber and super engineering plastics in one stage of impregnation for 3D printing by fused deposition modelling. The method is carried out in the following way: carbon fiber is placed in an impregnating bath for impregnation with a solution of a polymer binder. Then molded at temperatures of 240-450°C in the process of drying from the solvent using metal dies with a diameter of at least 20% of the linear width of the original carbon fiber, installed directly in the drying oven. After that, the hot fiber leaving the furnace is passed through at least three guide rollers, while after each guide roller the direction of the hot fiber is changed to 90°, after which the resulting bundle is wound on a coil.

EFFECT: producing a semi-rigid bundle based on carbon fiber and super engineering plastics in one stage of impregnation for 3D printing by fused deposition modelling.
