POLYAMIDE COMPOSITE MATERIAL (VARIANTS) Russian patent published in 2008 - IPC C08L77/02 C08J5/16 

FIELD: composite materials.

SUBSTANCE: invention provides structural- and antifriction-destination six-block polyamide-based polymer material, which is, in particular, intended for manufacturing parts with low coefficient of friction and meeting requirements of shock and thermal stability. According to first embodiment, in polyamide composite material composed of six-block polyamide matrix and matrix-modifying carbon additive, said carbon additive is fullerene C₆₀ or fullerene C₇₀, or mixture thereof in amounts from 0.0001 to 1.5%. According to second embodiment, in polyamide composite material composed as above, said carbon additive is fullerene soot containing 3-16% fullerene C₆₀ or fullerene C₇₀, or mixture thereof and used in amount 0.01 to 3.0%.

EFFECT: addition of fullerene materials results increased strength and elasticity, reduced coefficient of friction with metals and wear, increased softening, melting and in-air destruction temperatures, and increased heat conductivity without deterioration in density and moisture absorption.
