Metallmatrixverbundkörper mit hoher Steifigkeit und hoher Stabilität in Längsrichtung

摘要

A long metal matrix composite material part comprises 35-45 vol.% aluminum alloy matrix and 65-55 vol.% continuous carbon fibers arranged in successive layers parallel to the length direction.≥90% of the fibers are ultra-high modulus fibers which are oriented, to the length direction, at 0 to plus or minus 5 degrees in 25-60% of the layers and at plus or minus 20 to plus or minus 40 degrees in the other layers. An Independent claim is also included for a similar long metal matrix composite material part in which the matrix comprises a magnesium alloy and the ultra-high modulus carbon fibers are oriented at 0 to plus or minus 5 degrees to the length direction in≥90% of the layers.
