A metal matrix composite is made by roll consolidating a sandwich formed from alternating layers of a matrix metal, a brazing alloy, and reinforcing fiber at elevated temperature and pressure. If made in a process using mandrels to impart the pressure and heat, such as a process described in U.S. Pat. No. 5,229,562, the metal matrix composite is kept separate from the mandrels by using a release agent or stop-off such as a layer of boron nitride between the mandrel and layup.
