CARBON FIBER REINFORCED COMPOSITE MATERIAL AND ITS MANUFACTURING METHOD
To provide a carbon fiber reinforced composite material that can suppress a generation of dust from a plate surface during processing in a conventional C/C composite material, chipping such as chipping during processing in a conventional SiC-C/C composite material, and a delamination, and can reduce a manufacturing process.SOLUTION: There is provided a carbon fiber reinforced composite material formed by laminating at least two layers of a first carbon fiber reinforced composite layer containing carbon fibers oriented in a first direction, and a second carbon fiber reinforced composite layer containing carbon fibers oriented in a second direction different from the first direction. At least one layer of the first carbon fiber reinforced composite layer is a carbon fiber reinforced silicon carbide composite layer impregnated with metallic silicon, and the carbon fiber reinforced silicon carbide composite layer forms at least one outermost surface layer of the carbon fiber reinforced composite material, in which a ratio of a thickness of the first carbon fiber reinforced composite layer to an entire carbon fiber reinforced composite material is larger than a ratio of a thickness of the second carbon fiber reinforced composite layer to the entire carbon fiber reinforced composite material.SELECTED DRAWING: Figure 1
【課題】従来のＣ／Ｃ複合材における加工時の板面からの粉塵の発生、従来のＳｉＣ－Ｃ／Ｃ複合材における加工時のチッピング等の欠けや層間剥離が抑制され、製造工程の削減を図ることも可能な炭素繊維強化複合材を提供する。【解決手段】第１の方向に配向している炭素繊維を含む第１の炭素繊維強化複合層と、該第１の方向とは異なる第２の方向に配向している炭素繊維を含む第２の炭素繊維強化複合層との少なくとも２層が積層されてなる炭素繊維強化複合材。該第１の炭素繊維強化複合層の少なくとも１層は、金属シリコンが含浸された炭素繊維強化炭化ケイ素複合層であり、該炭素繊維強化炭化ケイ素複合層が該炭素繊維強化複合材の少なくとも一方の最表面層を形成しており、該炭素繊維強化複合材全体に占める該第１の炭素繊維強化複合層の厚みの割合が、該炭素繊維強化複合材全体に占める該第２の炭素繊維強化複合層の厚みの割合より大きい。【選択図】図１
