Abstract

A laminate structure may include: an aluminum layer; a glass composite layer adjacent to the aluminum layer; and/or a carbon composite layer adjacent to the glass composite layer, opposite to the aluminum layer. The glass composite layer may include one or more glass-fiber-reinforced thermoplastic prepreg plies. The carbon composite layer may include one or more carbon-fiber-reinforced thermoplastic prepreg plies. A laminate structure may include: a first aluminum layer; a first glass composite layer adjacent to the first aluminum layer; a first carbon composite layer adjacent to the first glass composite layer, and opposite to the first aluminum layer; and/or a second glass composite layer adjacent to the first carbon composite layer, and opposite to the first glass composite layer. The first glass composite layer may include one or more glass-fiber-reinforced thermoplastic prepreg plies. The first carbon composite layer may include one or more carbon-fiber-reinforced thermoplastic prepreg plies.

Claims (52)

1. A laminate structure, consisting of:

an aluminum layer;

a glass composite layer, consisting of glass fibers and a first resin matrix, adjacent to the aluminum layer;

a carbon composite layer, consisting of carbon fibers and a second resin matrix, adjacent to the glass composite layer, and opposite to the aluminum layer; and

a single additional layer between the aluminum layer and the glass composite layer;

wherein the carbon composite layer comprises three or more carbon composite sublayers, and

wherein the additional layer is an adhesive layer.

2. The laminate structure of claim 1 , wherein the glass composite layer is configured to prevent galvanic corrosion due to interaction between the aluminum layer and the carbon composite layer.

3. The laminate structure of claim 1 , wherein the first resin matrix comprises thermoplastic resin.

4. The laminate structure of claim 3 , wherein the thermoplastic resin comprises polyetheretherketone (PEEK) or polyetherketoneketone (PEKK).

5. The laminate structure of claim 1 , wherein the second resin matrix comprises thermoplastic resin.

6. The laminate structure of claim 5 , wherein the thermoplastic resin comprises polyetheretherketone (PEEK) or polyetherketoneketone (PEKK).

7. The laminate structure of claim 1 , wherein the first resin matrix comprises first thermoplastic resin,

wherein the second resin matrix comprises second thermoplastic resin, and

wherein the first thermoplastic resin is the same as the second thermoplastic resin.

8. The laminate structure of claim 1 , wherein the first resin matrix comprises first thermoplastic resin,

wherein the second resin matrix comprises second thermoplastic resin, and

wherein the first thermoplastic resin differs from the second thermoplastic resin.

9. The laminate structure of claim 1 , wherein the additional layer at least partially reduces strain in the aluminum layer and strain in the glass composite layer due to differences in thermal contraction and/or expansion between the aluminum layer and the glass composite layer.

10. A laminate structure, consisting of:

an aluminum layer;

a glass composite layer, consisting of glass fibers and a first resin matrix, adjacent to the aluminum layer;

a carbon composite layer, consisting of carbon fibers and a second resin matrix, adjacent to the glass composite layer, and opposite to the aluminum layer; and

a single additional layer between the glass composite layer and the carbon composite layer;

wherein the carbon composite layer comprises three or more carbon composite sublayers, and

wherein the additional layer is an adhesive layer.

11. The laminate structure of claim 10 , wherein the additional layer at least partially reduces strain in the glass composite layer and strain in the carbon composite layer due to differences in thermal contraction and/or expansion between the glass composite layer and the carbon composite layer.

12. The laminate structure of claim 10 , wherein the first resin matrix comprises first thermoplastic resin,

wherein the second resin matrix comprises second thermoplastic resin, and

wherein the first thermoplastic resin is the same as the second thermoplastic resin.

13. The laminate structure of claim 10 , wherein the first resin matrix comprises first thermoplastic resin,

wherein the second resin matrix comprises second thermoplastic resin, and

wherein the first thermoplastic resin differs from the second thermoplastic resin.

14. The laminate structure of claim 10 , wherein the glass composite layer is configured to prevent galvanic corrosion due to interaction between the aluminum layer and the carbon composite layer.

15. A laminate structure, consisting of:

an aluminum layer;

a glass composite layer, consisting of glass fibers and a first resin matrix, adjacent to the aluminum layer;

a carbon composite layer, consisting of carbon fibers and a second resin matrix, adjacent to the glass composite layer, and opposite to the aluminum layer;

a single first additional layer between the aluminum layer and the glass composite layer; and

a single second additional layer between the glass composite layer and the carbon composite layer;

wherein the carbon composite layer comprises three or more carbon composite sublayers,

wherein the first additional layer is a first adhesive laver, and

wherein the second additional layer is a second adhesive layer.

16. The laminate structure of claim 15 , wherein the first additional layer at least partially reduces strain in the aluminum layer and strain in the glass composite layer due to differences in thermal contraction and/or expansion between the aluminum layer and the glass composite layer.

17. The laminate structure of claim 15 , wherein the second additional layer at least partially reduces strain in the glass composite layer and strain in the carbon composite layer due to differences in thermal contraction and/or expansion between the glass composite layer and the carbon composite layer.

18. The laminate structure of claim 15 , wherein the first resin matrix comprises first thermoplastic resin,

wherein the second resin matrix comprises second thermoplastic resin, and

wherein the first thermoplastic resin is the same as the second thermoplastic resin.

19. The laminate structure of claim 15 , wherein the first resin matrix comprises first thermoplastic resin,

wherein the second resin matrix comprises second thermoplastic resin, and

wherein the first thermoplastic resin differs from the second thermoplastic resin.

20. The laminate structure of claim 15 , wherein the glass composite layer is configured to prevent galvanic corrosion due to interaction between the aluminum layer and the carbon composite layer.
