CARBON FIBER COMPOSITE SHEET, USE THEREOF AS A HEAT CONDUCTOR AND PITCH-BASED CARBON FIBER WEB SHEET FOR USE IN THE SAME

摘要

A carbon fiber composite sheet comprising a pitch-based carbon fiber web and a matrix resin, whereincarbon fibers constituting the pitch-based carbon fiber web have a crystallite size in the hexagonal net plane direction of 5 nm or more and a thermal conductivity in the thickness direction of 1 W/(m·K) or more.;This carbon fiber composite sheet is used for radio shielding and heat conduction.
