DEVICE FOR PRODUCING FIBRE-REINFORCED POLYMER GRANULES Russian patent published in 2023 - IPC B29B9/14 B29B9/06 

FIELD: polymer materials.

SUBSTANCE: invention can be used in the manufacture of high-strength composite structural products from reinforced polymer granules. The device for production of fibre-reinforced polymer granules includes a device for supplying continuous fibre 1, spinneret 11, granulator 14, fluidization bath 4, calenders 10, cooling module 12, and polymer composite drawing module 13. These modules ensure successive passage of the fibre 2 from device for supplying continuous fibre 1, through fluidization bath 4, calenders 10, and spinneret 11 to cooling module 12 and drawing 13 to granulator 14. The calenders and the spinneret are heated. The fluidization bath contains an electrically conductive membrane horizontally located in its lower part, configured to be connected to high voltage source 9. The bottom of the bath includes compressed air supply pipe 6.

EFFECT: invention makes it possible to obtain granules with reinforcing fibres uniformly distributed in them, the length of which is comparable to the length of the granules.
