Title:
炭素-炭素複合材含浸用ピッチの製造方法
Document Type and Number:
Japanese Patent JP5135387
Kind Code:
B2
Abstract:
The present invention discloses a method for preparing an impregnating pitch which is used for the manufacture of carbon-carbon composites having excellent mechanical properties at an ultra high temperature, abrasion resistance and the like, wherein the impregnating pitch having a low viscosity and an improved carbonization yield is provided by facilitating cross-linking reactions between the aromatic compounds in the pitch, while eliminating heat treatment.
