CARBON FIBER COMPOSITE MATERIAL, OIL-FIELD EQUIPMENT AND METHOD FOR PRODUCING CARBON FIBER COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide: a carbon fiber composite material using carbon nanofibers; oil-field equipment using the carbon fiber composite material; and a method for producing the carbon fiber composite material.

SOLUTION: In this carbon fiber composite material 50, 0.01-0.70 pt.mass of carbon nanofibers with 0.4-7.0 nm average diameter are dispersed. The production method of the carbon fiber composite material comprises: mixing 0.01-0.70 pt.mass of carbon nanofibers with 0.4-7.0 nm average diameter with 100 pts.mass of an elastomer; and thereafter, performing tight milling at 0-50°C by using an open roller 2 with 0.5 mm or less roller gap d, to obtain a carbon fiber composite material 50.
