Abstract

A composite component includes a bonded portion and a component mount. The component mount is coupled to the bonded portion to move relative to the bonded portion. The bonded portion includes a fiber portion and a ceramic portion.

First claim

What is claimed is:

1. A composite component comprising
a bonded portion made from a ceramic matrix composite material and
an un-bonded portion made from the ceramic matrix composite material and coupled to the bonded portion to move relative to the bonded portion in response to application of a load to cause the composite component to deform in a controlled manner without fracture of the composite component,
wherein the un-bonded portion includes a first un-bonded section coupled to the bonded portion to move relative to the bonded portion in response to application of the load, a second un-bonded section coupled to the bonded portion to move relative to the bonded portion and the first un-bonded section in response to application of the load, and a third un-bonded section coupled to the bonded portion to move relative to the bonded portion, the first un-bonded section, and the second un-bonded section in response to application of the load.

2. The composite component of claim 1 , wherein the third un-bonded section is located between the bonded portion and the second un-bonded section and the second un-bonded section is located between the third un-bonded section and the first un-bonded section.

3. The composite component of claim 2 , wherein the composite component has a load vs. deflection curve including, in series, a first segment provided by the first un-bonded section and having a first slope, a second segment provided by the second un-bonded section and having a second slope, a third segment provided by the third un-bonded section and having a third slope, and a fourth segment provided by the bonded portion and having a fourth slope.

4. The composite component of claim 3 , wherein the second slope is greater than the first slope, the third slope is greater than the fourth slope, and the fourth slope is greater than the third slope.

5. A composite component comprising
a bonded portion made from a ceramic matrix composite material and
an un-bonded portion made from the ceramic matrix composite material and coupled to the bonded portion to move relative to the bonded portion in response to application of a load to cause the composite component to deform in a controlled manner without fracture of the composite component,
wherein the un-bonded portion includes a first lower un-bonded section coupled to the bonded portion to move relative to the bonded portion in response to application of the load, a second lower un-bonded section coupled to the bonded portion to move relative to the bonded portion and the first lower un-bonded section in response to application of the load, and a third lower un-bonded section coupled to the bonded portion to move relative to the bonded portion, the first lower un-bonded section, and the second lower un-bonded section in response to application of the load.

6. The composite component of claim 5 , wherein the un-bonded portion further includes a first upper un-bonded section coupled to the bonded portion to move relative to the bonded portion in response to application of the load, a second upper un-bonded section coupled to the bonded portion to move relative to the bonded portion and the first upper un-bonded section in response to application of the load, and a third upper un-bonded section coupled to the bonded portion to move relative to the bonded portion, the first upper un-bonded section, and the second upper un-bonded section in response to application of the load.

7. The composite component of claim 6 , wherein the bonded portion includes a first bonded section and a second bonded section and the second bonded section is located between the third lower and upper un-bonded sections, the second upper un-bonded section is located between the third upper un-bonded section and the first upper un-bonded section, and the second lower un-bonded section is located between the third lower un-bonded section and the first lower un-bonded section.

8. The composite component of claim 7 , wherein the composite component has a load vs. deflection curve including, in series, a first segment provided by the first lower and upper un-bonded sections and having a first slope, a second segment provided by the second lower and upper un-bonded sections and having a second slope, a third segment provided by the third upper and lower un-bonded sections and having a third slope, and a fourth segment provided by the second bonded section having a fourth slope and the first slope is greater than the second slope, the third slope is greater than the second slope, fourth slope is greater than the second and the third slopes, and the first slope and the fourth slope are about equal.

9. The composite component of claim 8 , further comprising a component mount coupled to the un-bonded portion and configured to apply the load which is a pre-loading of the un-bonded portion.

10. The composite component of claim 8 , further comprising a component mount coupled to the un-bonded portion and the load includes a first force applied by the component mount to the un-bonded portion and a second force applied to the bonded portion in a direction opposite the first force.

11. The composite component of claim 7 , wherein the composite component has a load vs. deflection curve including, in series, a first segment provided by the first lower and upper un-bonded sections and having a first slope, a second segment provided by the second lower and upper un-bonded sections and having a second slope, a third segment provided by the third upper and lower un-bonded sections and having a third slope, and a fourth segment provided by the second bonded section having a fourth slope, and a fifth section provided by the first, second, and third upper and lower section and the bonded portion, the first slope is greater than the second slope, the third slope is greater than the second slope, third slope is greater than the second and the third slopes, the first and second slopes are about equal, and the fifth slope is less than the second slope.

12. A composite component comprising
a bonded portion made from a ceramic matrix composite material and
an un-bonded portion made from the ceramic matrix composite material and coupled to the bonded portion to move relative to the bonded portion in response to application of a load to cause the composite component to deform in a controlled manner without fracture of the composite component,
wherein the bonded portion includes a first bonded section and a second bonded section and the second bonded section is appended to the first bonded section to extend away from the first bonded section, and
wherein the un-bonded portion includes a first un-bonded section appended to the second bonded section to move relative to the second bonded section in response to application of the load, a second un-bonded section appended to the second bonded section to move relative to the second bonded section and the first un-bonded section in response to application of the load, and a third un-bonded section appended to the second bonded section to move relative to the second bonded section, the first un-bonded section, and the second un-bonded section in response to application of the load.

13. The composite component of claim 12 , wherein the third un-bonded section is coupled to the first bonded section to translate relative to the first bonded section and appended to the second bonded section to pivot relative to the second bonded section, the second un-bonded section, and the first un-bonded section.

14. The composite component of claim 13 , wherein the second un-bonded section is coupled to the third un-bonded section to translate re
