<p>PROBLEM TO BE SOLVED: To provide a constituting member having high rigidity and high stability. SOLUTION: An extended metal matrix composite material is composed of, by volume, 35 to 45% aluminum base or magnesium base alloy matrix and 65 to 55% continuous carbon fibers arranged by sheets parallel to the longitudinal direction. In the case the matrix is composed of an aluminum base, as for the ones of 25 to 60% among the plural sheets, the fibers are arranged at 0 deg.±5 deg. with respect to the longitudinal direction of the constituting member. In the other sheets, the fibers are arranged at±20 deg. or±40 deg. with respect to a prescribed direction. In the case the matrix is composed of a magnesium base, the fibers having an ultrahigh coefficient are arranged at 0 deg.±5 deg. in at least 90% of the sheets. This material imparts high rigidity and high stability in a prescribed direction and is suitable for application in the aerospace industry.</p> |
