PURPOSE:To provide a carbon fiber grown in gaseous phase, originated from carbon fiber grown in nascent gaseous phase and giving a composite material having excellent mechanical properties when compounded to a matrix material such as plastics. CONSTITUTION:The objective carbon fiber grown in gaseous phase has a diameter of <=5mum, a length of <=100mum, an average aspect ratio of 2-100 and rugged broken end. The carbon fiber having the above characteristics can be produced by breaking a carbon fiber grown in nascent gaseous phase by high impact force caused by the collision of small particles, etc. |
