A preformed fiber reinforced metal matrix composite reinforcement insert is clad or covered with a material that is effective to avoid the adverse reactions between the insert/melt and any exposed insert fibers/matrix. The clad insert is suspended in the mold cavity and a melt is introduced into the mold cavity about the clad insert. The melt is solidified about the clad insert to provide a casting of the solidified melt having the clad insert disposed therein to reinforce the casting.
