Abstract
(EN) This invention provides a composite material that can effectively utilize the properties of a metal powder base material per se or further added ceramic, and ceramic base material per se, and excellent electric conductivity and thermal conductivity and strength properties possessed by a fibrous carbon material formed of graphene. To this end, a fibrous carbon material formed of graphene such as carbon nanotubes or vapor phase grown carbon fibers is incorporated, followed by discharge plasma sintering for integration to produce a metal sinter or a mixed sinter composed of a metal and ceramic or a ceramic sinter. The incorporation of the fibrous carbon material formed of graphene can improve various properties such as thermal conductivity and electric conductivity possessed by the metal material. Although the rollability of the sinter is lower than a fibrous carbon material-free material, the sinter can be rolled. When the selection of various conditions, for example, rolling conditions such as rolling direction and rolling reduction and number of times of rolling, and annealing after rolling is taken into consideration, Young’s modulus and elongation, residual stress or other ductile properties and various other properties can be regulated without causing a change in tensile strength after rolling.
(FR) La présente invention concerne un matériau composite pouvant utiliser efficacement les propriétés d’un matériau de base de poudre de métal en soi ou un matériau en céramique et céramique ajoutée en soi, une excellente conductivité électrique et une conductibilité thermique et des propriétés de résistance présentées par un matériau carboné fibreux formé de graphène. A cette fin, on procède à l’incorporation d’un matériau carboné fibreux formé de graphène, tel que des nanotubes de carbone ou des fibres de carbone produites en phase vapeur, puis à un frittage par décharge plasma pour l’intégration en vue de produire un frittage métal ou un frittage mixte composé d’un frittage métallique et céramique ou d’un frittage céramique. L’incorporation du matériau carboné fibreux formé de graphène peut améliorer différentes propriétés comme la conductibilité thermique et la conductivité électrique que possède le métal. Bien que le coefficient de roulement du frittage soit inférieur à celui d’un matériau exempt de matériau carboné fibreux, il est possible de rouler le frittage. Une fois prise en considération la sélection des différentes conditions, par exemple les conditions de roulement comme la direction de roulement et la réduction de roulement et le nombre de cycles de roulement, et le recuit faisant suite au roulement, il est possible de réguler le module de Young et l’étirement, la contrainte résiduelle ou d’autres propriétés ductiles ainsi que de nombreuses autres propriétés, sans provoquer de modification dans la résistance à la traction après le roulement.
(JA)  金属粉体基材自体あるいはさらに添加するセラミックス、更にはセラミックス基材自体の有する特性とともに、グラフェンからなる繊維状炭素材料が有する優れた電気伝導と熱伝導特性並びに強度特性を有効活用した複合材料を提供する。これを実現するために、カーボンナノチューブや気相成長炭素繊維などのグラフェンからなる繊維状炭素材料を配合して放電プラズマ焼結により一体化した金属焼結体または金属とセラミックスとの混合焼結体もしくはセラミックス焼結体を製造する。グラフェンからなる繊維状炭素材料の配合により、金属材料が有する熱伝導性や電気伝導性などの諸特性を向上させることができる。繊維状炭素材料を含有しない材料に比較して圧延性は低下するが、圧延することは可能であり、圧延方向や圧化率、圧延回数などの圧延条件並びに圧延後の焼鈍等を種々選定考慮することで、圧延後の引張り強さは変化することなくヤング率や伸び、残留応力などの延性や種々特性を制御することが可能である。
