Abstract
A ceramic matrix composite system includes multiple stacked layers of ceramic fiber cloth impregnated with resin matrix material. The resin matrix material in each of the fiber cloth layers substantially remains with the same layer during subsequent processing. Ceramic-containing material inner layers are applied between each of the fiber cloth layers enhancing the cross ply strength of the composite system.
Claims20
A matrix composite system comprising:
- at least two layers of cloth, the cloth characterized by a plurality of fibers arranged in a plane and adjacent to each other, each layer including a predetermined amount of dry impregnated resin matrix material, wherein the resin matrix material of each of the at least two layers substantially remains with the respective layers during subsequent processing;
- and
- a third material layer applied in the interspace between each of the at least two layers, the third material layer having similar mechanical and physical properties as the resin matrix material, and bonded to the adjacent layers wherein the at least two layers and the intervening third material layer are cured to form the composite system.
A method of producing a component by a ceramic matrix composite system, the steps comprising:
- providing at least two layers of impregnated ceramic fiber cloth with a predetermined amount of dry impregnated resin matrix material, wherein the resin matrix material of each of the at least two layers substantially remains with the respective layer during subsequent processing;
- applying at least one ceramic-containing material intervening layer between each of the at least two layers, the intervening layer having similar mechanical and physical properties as the resin matrix material;
- debulking the at least two layers and the intervening at least one ceramic-containing material layer;
- applying pressure to the at least two layers to produce a desired geometry for the at least two layers and the intervening at least one ceramic-containing material layer;
- applying a predetermined amount of heat and pressure to the at least two layers and the intervening at least one ceramic-containing material layer;
- and
- sintering the at least two layers and the intervening at least one ceramic-containing material layer.
