Abstract
A composite structure includes a first brittle core structure and supportive surrounding structure with a bond formed between the first brittle core structure and the supportive surrounding structure. The composite structure is formed by positioning an outer material in a cavity of a sintering device. Then depositing an inner material in the outer material. Then applying a pressure to the outer material and the inner material, and heating the outer material and the inner material to a sintering temperature of at least one of the outer material and the inner material while applying the pressure.
Claims20
A composite structure comprising:
- a first brittle core material;
- a fiber reinforced composite material radially surrounding the first brittle core material;
- and
- a chemical bond between a radially outer surface of the first brittle core material and a radially inner surface of the fiber reinforced composite material.
A method of forming a composite structure, the method comprising:
- positioning an outer material in a cavity of a sintering device;
- depositing an inner material in the outer material;
- applying a pressure to the outer material and the inner material;
- and
- heating the outer material and the inner material to a sintering temperature of at least one of the outer material and the inner material while applying the pressure, the inner material exhibiting a higher hardness than the outer material after applying the pressure and heating the outer material and the inner material.
A method of forming a composite structure, the method comprising:
- depositing a first base material powder into a cavity of a sintering assembly;
- depositing a sintered ceramic structure over the first base material powder;
- depositing a second base material powder over the sintered ceramic structure;
- applying a pressure to the first base material powder, the sintered ceramic structure, and the second base material powder within the cavity;
- and
- heating the first base material powder, the sintered ceramic structure, and the second base material powder within the cavity to a sintering temperature of the first base material powder and the second base material powder while applying the pressure.
