Abstract
A method for fabricating a ceramic composite includes forming a first ceramic composite layer (CCL), positioning a form against the first CCL, positioning a second CCL against the form such that the form is at least partially circumscribed by the first CCL and the second CCL. The method also includes coupling the first CCL to the second CCL, such that at least a first passage extends in a first direction across at least a portion of the ceramic composite component and is defined at least partially by the first CCL and the second CCL in a location vacated by the first form.

A method for fabricating a ceramic composite component, said method comprising:
- forming a first ceramic composite layer (CCL);
- positioning a first form against the first CCL;
- positioning a second form against the first CCL;
- positioning a second CCL against a first side of the first form, such that the first form is at least partially circumscribed by the first and second CCLs and the second form is encased by the first and second CCLs, wherein the first and second CCL CCLs are positioned such that first sides of the first and second CCLs form a shape that is substantially complementary to a shape of the first and second forms, and such that second opposing sides of the first and second CCLs define exterior surfaces of the component;
- positioning at least a third CCL against the first form, such that the third CCL extends across the component from the first side of the first form to an opposite side of the first form;
- and
- coupling the first CCL to the second CCL, such that at least a first passage extending in a first direction across at least a portion of the ceramic composite component is defined at least partially by the first CCL and the second CCL in a location vacated by the first form, and a second passage is defined by the first CCL and the second CCL in a location vacated by the second form such that the second passage is sealed within the component and is defined entirely within the component.
A method for fabricating a ceramic composite component, said method comprising:
- forming a first ceramic composite layer (CCL);
- positioning at least a first form against the first CCL;
- positioning at least a second CCL against a first side of the first form and at least partially across the component, such that the first form is at least partially circumscribed by the first CCL and the at least a second CCL, wherein the first and second CCLs are positioned such that first sides of the first and second CCLs form a shape that is substantially complementary to a shape of the first form, and such that second opposing sides of the first and second CCLs define exterior surfaces of the component;
- positioning at least a third CCL against the first form, such that the third CCL extends across the component from the first side of the first form to an opposite side of the first form;
- coupling the first and second CCLs together, such that at least a first passage extending in a first direction across at least a portion of the ceramic composite component is defined in a location vacated by the first form;
- and
- inserting a structural support into the first passage to facilitate enhancing the structural strength of the component.
