Title:
高熱伝導複合材料
Document Type and Number:
Japanese Patent JP5116082
Kind Code:
B2
Abstract:
A composite material being excellent in heat conductivity is provided. In order to realize this, a fibrous carbonmaterial made of fine tube form structures constituted with single-layer or multiple-layer graphene is present to form a plurality of layers within a substrate made from a spark plasma sintered body of a metal powder, a mixed powder of a metal and ceramics, or a ceramic powder. The fibrous carbonmaterial constituting each layer is made of a mixture obtained by mixing a small amount of a small diameter fiber 2 having an average diameter of 100 nm or less with a large diameter fiber 1 having an average diameter of 500 nm to 100 µm.
