FIELD: chemistry.
SUBSTANCE: external diametre of carbon fibres is 15-100 nm. The fibrous structure includes a knot whereto said carbon fibres are connected so that the specified carbon fibres come out from the knot made from growing carbon fibres with size 1.3 times exceeding external diametre of carbon fibres. Once added to hard materials, such as resin, ceramics, metal, carbon fibrous structures taken even in small amount improve physical properties of materials, including electric, mechanical, or thermal properties, not mentioning other material properties.
EFFECT: improved thermal properties.
