COMPOSITE MATERIAL Russian patent published in 2019 - IPC B29C64/00 C08L81/00 

FIELD: construction materials.

SUBSTANCE: invention relates to the field of composite material development, intended as the super-structural materials used in 3D printing by the fused deposition modeling (FDM) method, that is, the three-dimensional objects creation by the material successive layers application that repeat the digital model contours. Described is a composite material according to the present invention, which is produced by the polyphenylene sulfone (PPSn) with the glass transition temperature of 200.5 °C extrusion mixing, with the high molecular weight PPSn with the glass transition temperature of 214 °C together with the ground carbon fibers based filler.

EFFECT: technical result consists in that intended for 3D printing produced composite material has improved mechanical characteristics.
