METHOD OF PRODUCING REINFORCED FIBRE POLYMER COMPOSITION Russian patent published in 2019 - IPC B29B7/48 B29C48/156 

Abstract RU 2686217 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a fibre-reinforced polymer composition. Technical result is achieved by a method of producing a fibre-reinforced polymer composition which includes steps of: a) providing a polymer composition, b) melting the polymer composition in the compounding device, c) feeding non-woven material to the compounding device in the presence of a melted polymer composition and d) removing the fibre-reinforced polymer composition from the compounding device. Nonwoven material contains reinforcing fibres selected from carbon fibres, glass fibre or mixtures thereof.

EFFECT: technical result is uniform distribution of reinforcing fibres in polymer composition with low degree of mixing.
