Abstract

The present invention relates to a high-strength, high-productivity perform wire for a carbon fiber reinforced aluminum composite material, which comprises: a continuous fiber bundle of carbon filaments having a 2/3-width ranging from 25 to 75 cm.sup.-1, as measured on the basis of Raman spectroscopy, the 2/3-width corresponding to 2/3 of the peak level of a Raman band obtained corresponding to a wave number of about 1,585 cm.sup.-1, the peak level attributed to E.sub.2g symmetric vibration of a graphite structure; one or two materials selected from the group consisting of carbon, silicon carbide, titanium, titanium carbide, boron, and titanium boride, the material(s) covering the individual fibers constituting the continuous fiber bundle; and a matrix consisting essentially of aluminum or aluminum alloy each of which contains 0.1% or less of copper and 0.45% or less of silicon, both by weight based on the weight of matrix, and infiltrated into the continuous fiber bundle.
