COMPOSITE MATERIAL Russian patent published in 2019 - IPC C08L81/06 C08K7/04 C08K7/14 B29C41/02 B29C64/10 

FIELD: chemistry.

SUBSTANCE: invention relates to composite materials intended for additive production technologies. Composite material comprises the following components, wt%: 40–65 of thermoplastic polymer, 10–20 of plasticizer, 25–40 of filler. Thermoplastic polymer used is polyphenylene sulfone with an intrinsic viscosity of 0.45 dl/g. As plasticizer, a polyphenylene sulphon oligomer based 4,4'-dihydroxydiphenyl and 4,4'-dichlorodiphenylsulphone with molecular weight of 15,000 g/mol and characteristic viscosity of 0.1 dl/g is used. Filler used is glass fiber or carbon fiber.

EFFECT: invention improves strength characteristics of the composite material.
