Abstract
A metal-polymer-metal laminate is made by joining adjacent laminate sections in a staggered relationship. Terminal portions of metal layers in a first laminate section are opposed to ends of fiber-reinforced polymer layers in a second laminate section. End portions of fiber-reinforced polymer layers in the first laminate section are opposed to ends of metal layers in a second laminate section. The two laminate sections are then joined by an adhesive layer.

A metal-polymer-metal laminate (45) made by adhesively joining adjacent laminate sections, said laminate (45) comprising:
- (a) a first laminate section (10) comprising:
- (i) a first metal layer (11);
- (ii) a second metal layer (15) having a lateral end (16), said second metal layer (15) being laterally non-coextensive with the first metal layer (11);
- and
- (iii) a fiber-reinforced first polymer layer (20) between said first metal layer (10) and second metal layer (15), said first polymer layer (20) having a lateral end (21);
- (b) a second laminate section (30) comprising:
- (i) a first metal layer (31) opposed to a metal layer (15);
- (ii) a second metal layer (35) having a lateral end (36) opposed to the lateral end (21) of a polymer layer (20), said second metal layer (35) being laterally non-coextensive with the first metal layer (31);
- and
- (iii) a fiber-reinforced first polymer layer (40) between said first metal layer (31) and second metal layer (35), said first polymer layer (40) having a lateral end (41) opposed to the lateral end (16) of a metal layer (15) in the first laminate section (10);
- and
- (c) an adhesive layer (50) interposed between said first and second laminate sections (10, 30) and adhesively joining them together.
A metal-polymer-metal laminate (400) made by joining adjacent laminate sections, said laminate (400) comprising:
- (a) a first laminate section (200) comprising:
- (i) a first metal layer (201) having a lateral edge (202);
- (ii) a second metal layer (211) spaced from said first metal layer (201) and having a lateral edge (212);
- (iii) a third metal layer (221) intermediate said first metal layer (201) and second metal layer (211), said third metal layer (221) having a lateral edge (222) spaced laterally inwardly of the lateral edges (202, 212) of said first and second metal layers (201, 211);
- (iv) a fiber-reinforced first polymer layer (231) between the first and third metal layers (201, 221), said first polymer layer (231) having a lateral edge (232) spaced laterally inwardly of the lateral edges (202, 212) on said first and second metal layers (201, 211);
- and
- (v) a fiber-reinforced second polymer layer (241) between the second and third metal layers (211, 221), said second polymer layer (241) having a lateral edge (242) spaced laterally inwardly of the lateral edges (202, 212) on said first and second metal layers (201, 211);
- said first, second and third metal layers (201, 211, 221) and said first and second polymer layers (231, 241) defining a slot (245);
- (b) a second laminate section (250) comprising:
- (i) first, second, third and fourth metal layers (251, 261, 271, 281), said second and third metal layers (261, 271) each having a lateral edge (262, 272) opposed to a lateral edge (232, 242) of a polymer layer (231, 241) in the first laminate section (200);
- and
- (ii) fiber-reinforced first, second and third polymer layers (301, 311, 321) between the metal layers (251, 261, 271, 281), said polymer layers (301, 311, 321) each having a lateral edge (302, 312, 322) opposed to a lateral edge (202, 222, 212) of a metal layer (201, 221, 211) in the first laminate section (200);
- and
- (c) an adhesive layer (350) joining said first laminate section (200) to the second laminate section (250).
