Abstract
A method of manufacturing ceramic matrix composite objects is disclosed. The method comprises the steps of providing first and second substantially two dimensional arrangements of one or more fiber plies, and machining the first and second arrangements to predetermined configurations to form first and second preforms. The second preform is made to conform to a surface of the first preform such that at least some of the fibers of the second preform are orientated at least partially in a plane outside that defined by the fibers of the first preform, and fixed to the first preform to form a combined first and second preform. The combined first and second preform is rigidized. Ceramic matrix composite objects manufactured by this method are also disclosed.
