Title:
CARBON FIBER-REINFORCED CARBON COMPOSITE MATERIAL AND SLIDING MATERIAL PRODUCED THEREWITH
Document Type and Number:
Japanese Patent JPH05345669
Kind Code:
A
Abstract:
PURPOSE: To provide a carbon fiber-reinforced carbon composite material having excellent abrasion resistance.
CONSTITUTION: A short carbon fiber bundle composed of plural single fibers and free from collecting agent is opened and impregnated with a resin or a pitch to obtain a prepreg. The prepreg sheets are laminated, formed, baked at ≤2000°C and subjected to repeated pitch-impregnation and baking at ≤2000°C to obtain a carbon fiber-reinforced carbon composite material having a final porosity of ≤10vo1.%.
