POLYMER COMPOSITION FOR STRUCTURAL PURPOSES Russian patent published in 2009 - IPC C08L77/10 C08L61/20 C08J5/14 C08K7/02 D06M15/41 D06M15/55 C04B14/38

Abstract RU 2374279 C2

FIELD: chemistry.

SUBSTANCE: invention can be used for making friction bearings, seals, gear wheels and other structural components of machines and mechanisms. The polymer composition contains 35 to 45 wt % thermoreactive resin - phenolformaldehyde or epoxy resin and 55 to 65 wt % granulated para-aramid fibre Rusar-S. This increases compression strength of the composition by 11 to 12%, impact strength by 1.54 to 1.6 times, and reduces anisotropy factor by 1.14 to 1.3 times.

EFFECT: design of an efficient method of producing polymer compositions based on thermoreactive binder and fibre filler.
