Laminate structure and wearable article
A laminate structure comprises a protective layer and a backing structure. The backing structure comprises a first support layer comprising an aerogel and a second support layer comprising a polymer and is arranged so that the second support layer is provided between the protective layer and the first support layer.
1. A laminate structure, comprising:
a plurality of protective layers arranged as a stack, wherein a part of each protective layer is moveable relative to at least one other protective layer in the stack and wherein a part of each protective layer is connected to at least one other protective layer in the stack so as to restrict relative movement of a part of each of the protective layers; and
a backing structure comprising a first support layer comprising an aerogel and a second support layer comprising a polymer, wherein the backing structure is arranged so that the second support layer is provided between the plurality of protective layers and the first support layer,
wherein the second support layer further comprises graphene; and
wherein the plurality of the protective layers in the stack are formed from a single sheet of high-tensile material folded to form the plurality of protective layers, the folds providing the connection between the protective layers in the stack.
2. The laminate structure of claim 1 , further comprising at least one additional backing structure comprising a first support layer comprising an aerogel and a second support layer comprising a polymer, such that the laminate structure comprises a plurality of backing structures.
3. The laminate structure of claim 2 , wherein the backing structures are arranged so that the first support layers and second support layers in the laminate structure alternate.
4. The laminate structure of claim 3 , wherein the laminate structure further comprises at least one additional protective layer provided between each of the backing structures.
5. The laminate structure of claim 4 , wherein each additional protective layer is provided on the corresponding second support layer of each of the backing structures.
6. The laminate structure of claim 1 , wherein the plurality of protective layers comprise a high-tensile layer.
7. The laminate structure of claim 1 , wherein the plurality of protective layers comprise a polymer and/or carbon-based material.
8. The laminate structure of claim 7 , wherein the plurality of protective layers comprise the high-tensile material selected from the group consisting of aramid fibres, aromatic polyamide fibres, boron fibres, ultra-high molecular weight polyethylene, poly(p-phenylene-2,6-benzobisoxazole) (PBO), poly{2,6-diimidazo[4,5-b:4′,5′-e]-pyridinylene-1,4(2,5-dihydroxy)phenylene} (PIPD) and combinations thereof.
9. The laminate structure of claim 1 ,
wherein the second support layer in the backing structure is disposed on the corresponding first support layer in the backing structure; and/or
wherein the second support layer extends around the first support layer so as to surround the aerogel.
10. The laminate structure of claim 1 , wherein the aerogel is a polyimide aerogel.
11. The laminate structure of claim 1 ,
wherein the first support layer has a thickness of 50 μm to 500 μm; and/or
wherein the second support layer has a thickness of 5 μm to 50 μm.
12. The laminate structure of claim 1 , further comprising a fastening element arranged to secure the plurality of protective layers to the backing structure, the fastening element being provided along an edge of the laminate structure.
13. The laminate structure of claim 1 , wherein the plurality of protective layers comprises a weaved arrangement of wound fibres.
14. The laminate structure of claim 1 , wherein each protective layer of the stack is connected to at least one adjacent protective layer at or adjacent an edge of each protective layer, optionally wherein each protective layer is connected to at least one adjacent protective layer at or adjacent the edges of the protective layer so as to constrain movement of a part of protective layer around the perimeter of each protective layer.
15. The laminate structure of claim 1 ,
wherein the polymer of the second support layer is an elastomer; or
wherein the polymer of the second support layer is selected from at least one of polyurethane, polyethylene, polypropylene, polyester, polyamide, polyimide and/or an epoxy resin.
16. The laminate structure of claim 1 ,
wherein the polymer of the second support layer is an elastomer; and
wherein the polymer of the second support layer is selected from at least one of polyurethane, polyethylene, polypropylene, polyester, polyamide, polyimide and/or an epoxy resin.
