Abstract The effect of different regimes of heat treatment on the tensile strength of SiCcoated composite wires of carbon fibers reinforced Al has been investigated. Their tensilestrength may increase under treatment either at 500℃ for 2 h or 550℃ for 1h, but decrease over600℃. After the strength tests of extracted fibers from composite wires, the SiC coating is an ex-cellent protection to carbon fibers, EPMA and EDAX showed that the C/Al interface of thecomposite wires is stable under treatment below 600℃, but unstable at 650℃.
