Abstract

The present disclosure provides a laminate structure including a laminate body with a second ply positioned between a first ply and a third ply, the second ply having an edge extending outward from a corresponding edge of the first and third plies. The laminate structure further includes a flange positioned on the edge of the second ply. The flange includes a first finger and a second finger extending outward to define a receptacle that receives the edge of the second ply therein.

First claim

What is claimed is:

1. A laminate structure comprising:
a laminate body comprising a second ply positioned between a first ply and a third ply, the second ply having an edge extending outward from a corresponding edge of the first and third plies; and
a flange positioned on the edge of the second ply and having a first finger and a second finger extending outward to define a receptacle that receives the edge of the second ply therein,
wherein the flange comprises steel and the first and third plies comprise titanium.

2. The laminate structure of claim 1 , wherein the second ply comprises aluminum.

3. The laminate structure of claim 1 , wherein the flange is a laminate formed of a plurality of plies.

4. The laminate structure of claim 1 , wherein the width of the flange is less than about 100 millimeters.

5. The laminate structure of claim 1 , wherein the at least one of the first and second fingers comprise at least one hole formed therethrough.

6. The laminate structure of claim 5 , further comprising a fourth ply, wherein the first ply is positioned between the second and fourth plies, and wherein the second and fourth plies are in contact through the at least one hole.

7. A laminate structure comprising:
a laminate body comprising a second ply positioned between a first ply and a third ply,
the second ply having an edge extending outward from a corresponding edge of the first and third plies; and
a flange positioned on the edge of the second ply and having a first finger and a second finger extending outward to define a receptacle that receives the edge of the second ply therein,
wherein the flange comprises steel, and
wherein the laminate body comprises a first set of plies alternately layered with a second set of plies having a composition different from that of the first set of plies, and wherein at least one of the first set of plies and the second set of plies has a thickness dimension that decreases in a thickness direction of the laminate body.

8. The laminate structure of claim 7 , wherein the second ply comprises aluminum.

9. The laminate structure of claim 7 , wherein the flange is a laminate formed of a plurality of plies.

10. The laminate structure of claim 7 , wherein the width of the flange is less than about 100 millimeters.

11. The laminate structure of claim 7 , wherein the at least one of the first and second fingers comprise at least one hole formed therethrough.

12. The laminate structure of claim 11 , further comprising a fourth ply, wherein the first ply is positioned between the second and fourth plies, and wherein the second and fourth plies are in contact through the at least one hole.

13. A laminate structure comprising:
a flange having a first projection extending outward from the flange and having at least one hole formed therethrough; and a laminate body comprising a second ply positioned between a first ply and a third ply, the second ply having an edge extending inward from a corresponding edge of the first and third plies, the laminate body configured to receive the first projection in the flange, wherein the first ply is connected to the third ply through the hole in the projection, wherein the first and third plies comprise titanium, and
wherein the second ply comprises aluminum.

14. The laminate structure of claim 13 , wherein the flange comprises a steel flange.

15. The laminate structure of claim 13 , wherein the flange is a laminate formed of a plurality of plies.

16. The laminate structure of claim 13 , wherein the width of the flange is less than about 100 millimeters.

17. A method of making the laminate structure of claim 1 , comprising: providing a laminate body comprising a second ply positioned between a first ply and a third ply, the second ply having an edge extending outward from a corresponding edge of the first and third plies; providing a flange positioned on the edge of the second ply and having a first finger and a second finger extending outward to define a receptacle that receives the edge of the second ply therein; assembling the steel flange with the laminate body to form a laminate structure; and compressing the laminate structure.

18. The method of claim 17 , wherein the flange is a laminate formed of a plurality of plies.

19. The method of claim 17 , wherein the at least one of the first and second fingers comprise at least one hole formed therethrough.

20. The method of claim 19 , the laminate structure further comprising a fourth ply, wherein the first ply is positioned between the second and fourth plies, and wherein the second and fourth plies are in contact through the at least one hole.

21. The method of claim 20 , wherein the step of compressing the laminate structure further comprises flowing the at least one of the second and fourth plies into the at least one hole in the flange to connect the second and fourth plies.

22. The method of claim 17 , wherein the laminate body comprises a first set of plies alternately layered with a second set of plies having a composition different from that of the first set of plies, and wherein at least one of the first set of plies and the second set of plies has a thickness dimension that decreases in a thickness direction of the laminate body.
