  • Carbon fiber-reinforced carbon composite and method of manufacturing the same
    Patent number: 10549503
    Abstract: A plate-shaped carbon fiber-reinforced carbon composite has a longitudinal length-to-widthwise length ratio of more than 1. The carbon fiber-reinforced carbon composite is such that at least two layers that are a first carbon fiber-reinforced carbon composite layer in which carbon fibers are placed in the carbonaceous matrix and are oriented in the longitudinal direction and a second carbon fiber-reinforced carbon composite layer different in the arrangement of the carbon fibers from the first carbon fiber-reinforced carbon composite layer are stacked, the first carbon fiber-reinforced carbon composite layer forms an outermost layer of at least one plate surface, the thickness thereof is 70% or more of the thickness of the carbon fiber-reinforced carbon composite, and the longitudinal bending elastic modulus is 150 GPa or more.
