CARBON FIBER-REINFORCED CARBON COMPOSITE MATERIAL AND METHOD FOR PRODUCING CARBON FIBER-REINFORCED CARBON COMPOSITE MATERIAL
PROBLEM TO BE SOLVED: To provide a carbon fiber-reinforced carbon composite material which has sufficient strength, hardly causes dust emission, and highly reduces the occurrence of deformation (such as warpage, cracking, and chipping) without increasing the weight and volume even when used under high temperature.SOLUTION: There is provided a carbon fiber-reinforced carbon composite material 1 containing a carbon fiber and a carbonaceous matrix, which comprises second carbon fiber-reinforced carbon composite layers 3,3' containing a unidirectional carbon fiber as the carbon fiber on at least one principal surface of a first carbon fiber-reinforced carbon composite layer 2 containing a woven fabric carbon fiber or a nonwoven carbon fiber as the carbon fiber, in which the second carbon fiber-reinforced carbon composite layers 3,3' have a plurality of convex parts and a plurality of concave parts which are alternately disposed separately in parallel with each other on the outside principal surface, and the plurality of convex parts and concave parts extend in the orientation direction of the unidirectional carbon fiber constituting the second carbon fiber-reinforced carbon composite layers 3,3'.SELECTED DRAWING: Figure 2
【課題】十分な強度を有するとともに、発塵を生じ難く、高温下で使用された場合であってもその重量や容量を増大させることなく変形（反り、ひび割れ、欠け等）の発生を高度に低減する炭素繊維強化炭素複合材の提供。【解決手段】炭素繊維及び炭素質マトリックスを含む炭素繊維強化炭素複合材１であって、前記炭素繊維として織布炭素繊維または不織布炭素繊維を含む第一の炭素繊維強化炭素複合層２の少なくとも一方の主表面上に、前記炭素繊維として一方向性炭素繊維を含む第二の炭素繊維強化炭素複合層３、３’を備え、第二の炭素繊維強化炭素複合層３、３’が、外側主表面上に、互いに離間して平行に交互配置された複数の凸条部と複数の凹条部とを有し、第二の炭素繊維強化炭素複合層３，３’を構成する一方向性炭素繊維の配向方向に前記複数の凸条部及び凹条部が伸長している炭素繊維強化炭素複合材１。【選択図】図２
