The present invention provides a metal matrix composite having stable performance without extremely weak portions and capable of assuring strength with a simple structure, the metal matrix composite being formed by hot-pressing or hot-isostatic-pressing a flat formation of reinforcing fibers sandwiched between metal matrices and comprising a joined end part in the longitudinal direction of reinforcing fibers which is joined obliquely at a joining angle of 5 to 60 degrees with respect to the longitudinal direction of reinforcing fibers or more preferably wherein a plurality of metal matrices and a plurality flat formations of reinforcing fibers are lapped each other to form layers of metal matrices and flat formations of reinforcing fibers so that the adjacent upper layers of flat formations of reinforcing fibers and the adjacent lower layers of flat formations of reinforcing fibers to a layer having a joined part of flat formations of reinforcing fibers are continuous and have no joined parts.
Composite à matrice métallique de performance stable, sans partie extrêmement faible et pouvant assurer la résistance d'une structure simple. Le composite à matrice métallique est formé par la compression à chaud ou la compression isostatique à chaud d'une structure plate de fibres de renforcement intercalée entre des matrices métalliques et comprenant une partie jointive d'extrémité, dans la direction longitudinale des fibres de renforcement, jointe obliquement selon un angle de 5 à 60 degrés, ou plus, par rapport à la direction longitudinale des fibres de renforcement. De préférence, plusieurs matrices de métal et plusieurs structures plates de fibres de renforcement se chevauchent pour former des couches de matrices métalliques et de structures plates de fibres de renforcement, de sorte que les couches supérieures et inférieures de structures plates de fibres de renforcement adjacentes à une couche ayant une partie jointe de structures plates de fibres de renforcement soient continues et n'aient elles-mêmes aucune partie jointe.
