Ceramic matrix composite articles include, for example a first plurality of plies of ceramic fibers in a ceramic matrix defining a first extent, and a local at least one second ply in said ceramic matrix defining a second extent on and/or in said first plurality of plies with the second extent being less than said first extent. The first plurality of plies has a first property, the at least one second ply has at least one second property, and said first property being different from said at least one second property. The different properties may include one or more different mechanical (stress/strain) properties, one or more different thermal conductivity properties, one or more different electrical conductivity properties, one or more different other properties, and combinations thereof.

A dynamoelectric machine having a permanent magnet rotor construction which contains the permanent magnets while inhibiting flux leakage. The invention further permits rapid, substantially conventional manufacturing techniques to be employed in the formation of rotor laminations used to build the rotors. Flux leakage and formation of reluctance components are inhibited either within the individual rotor laminations or along the length of the rotor by interleaving rotor lamination of different types. The rotor may further be constructed to absorb vibrations within the rotor core and insulate the rotor shaft. The rotor may be still further be constructed for counterbalancing the unbalance of a shaft on which the rotor is mounted.
