Abstract: A method for controlling the dimension of a reinforced metal matrix composite structure is taught. The structure is annular and the method is to render the structure non-round where the initial structure is essentially round. The cure of the essentially round condition is accomplished by forming a solid mandril very slightly smaller in dimensions than the final dimensions sought for the structure. The essentially round composite ring is forced onto the non-round mandril and heated to the relaxation temperature of the matrix. Because the mandril has a higher thermal coefficient of expansion than the matrix, the method is effective in forming an essentially round structure into a non-round configuration.
