Abstract:
The Composite Ceramic Structure embodying the principles of the present invention includes a structural composite laminar sheet having top and bottom layers that are equivalent in number and have an identical positioning in the laminar sheet relative to the middle layer. These identically positioned top and bottom layers are further symmetric in both geometry and material composition to alleviate warping during expansion or contraction due to temperature change. At least one top and at least one bottom layers form a metal matrix composite () and at least one middle layer (dense ceramic), impervious to metal infiltration, remains a dense ceramic (). The material combinations allow for the middle layer to have an in-plane residual compressive stress.
