<p>A carbon fiber structure of three-dimensional network composed of carbon fibers of 15 to 100 nm outer diameter, characterized in that the carbon fiber structure in a form having multiple carbon fibers extending outward, has granular parts where carbon fibers are bound to each other, the granular parts formed during the step of carbon fiber growth, the granular parts having a size of = 1.3 times the outer diameter of carbon fibers. This carbon fiber structure by addition of a small amount thereof enables enhancing of electrical properties, mechanical properties and thermal or other physical properties without detriment to the properties of the matrix.</p> |
