Abstract
Ceramic matrix composites include a fiber network and a matrix including layers of first and second materials. The first material may include SiC. The second material may include an element that when oxidized forms a silicate that is stable at high temperatures.
Claims20
A ceramic matrix composite, including:
- a network of fibers;
- a first matrix layer;
- and
- a second matrix layer containing an element that when oxidized forms a silicate that is stable at high temperatures.
1 more element
The ceramic matrix composite of claim 2, wherein the first matrix layer is SiC.
A ceramic matrix composite, including:
- a plurality of fibers;
- individual first matrix layers surrounding each fiber;
- and
- individual second matrix layers surrounding each of the individual first matrix layers, the individual second matrix layers including an element that when oxidized forms a silicate that is stable at high temperatures.
1 more element
A ceramic matrix composite, comprising:
- a first fiber;
- a first matrix layer surrounding the first fiber;
- a second matrix layer surrounding the first matrix layer, the second matrix layer including an element that when oxidized forms a silicate that is stable at high temperatures;
