FIELD: chemistry.
SUBSTANCE: composition contains low pressure, medium density polyethylene PE80B and chopped carbon fibres in amount of 10 wt %. The chopped carbon fibres used are based on polyacrylonitrile and have length of 5-6 mm and diameter of 5.4-6.0 mcm. Carbon nanofibres are catalytically grown on the surface of said chopped fibres in amount of 22-32 wt %.
EFFECT: improved physical and mechanical properties of the tube material, specifically high yield point and tensile modulus, breaking elongation and elongation at yield.
