To provide a ceramic matrix composite structure and to provide a method for preparing the same.
The ceramic matrix composite laminate (114) includes at least two directional, continuous ceramic fiber preform laminae (10) each being formed of interwoven or braided fibers. A layer of non-woven mat includes a plurality of chopped ceramic fibers (118) mixed with a bonding agent. The non-woven mat layer is interposed between the adjacent directional, continuous fiber preform laminae (10) to substantially eliminate interlaminar gaps formed between the adjacent directional continuous ceramic fiber preform laminae (10). The additional chopped fiber content improves the interlaminar mechanical and thermomechanical material properties of resulting ceramic matrix composite laminate (114).
