PHENOLIC-RESIN-COATED FINE CARBON FIBER AND PROCESS FOR PRODUCING THE SAME

Title:

PHENOLIC-RESIN-COATED FINE CARBON FIBER AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2006/003771

Kind Code:

A1

Abstract:

Phenolic-resin-coated fine carbon fibers which have excellent dispersibility and are usable as a filler in a matrix; and a process for producing the fibers. The process, which is for producing fine carbon fibers coated with a phenolic resin, is characterized by reacting a phenol with an aldehyde in the presence of a catalyst while mixing the reactants with fine carbon fibers which each has a multilayer structure composed of superposed cylindrical carbon layers having a fiber diameter of 0.5-500 nm and a fiber length of 1,000 µm or shorter and which each has a hollow structure in which the fiber axis extends. Thus, the surface of the fine carbon fibers is coated with a phenolic resin in an amount of 1-40 parts by weight per 100 parts by weight of the fine carbon fibers.
