Abstract
Official abstract text for this publication.
The present disclosure relates to a multilayer composite that may include a first porous layer, and a first barrier layer overlying the first porous layer. The first barrier layer may include a polyaramid material, a polyimide material, or any combination thereof. The multilayer composite may have a flame resistance rating of at least about 180° C. and a 50% strain compression rating of not greater than about 600 kPa.
First claim
Opening claim text (preview).
What is claimed is: 1. A multilayer composite comprising: a first porous layer comprising a silicone material, and a first barrier layer overlying the first porous layer, wherein the first barrier layer comprises a polyaramid material, a polyimide material, or any combination thereof, wherein the multilayer composite comprises a flame resistance rating of not greater than about 180° C., and wherein the multilayer composite comprises a 50% strain compression rating of not greater than about 600 kPa. 2. The multilayer composite of claim 1 , wherein the multilayer composite comprises a flame resistance rating of not greater than about 150° C. 3. The multilayer composite of claim 1 , wherein the composite comprises a 50% strain compression rating of not greater than about 400 kPa. 4. The multilayer composite of claim 1 , wherein the multilayer composite comprises a density of not greater than about 560 kg/m 3 . 5. The multilayer composite of claim 4 , wherein the multilayer composite comprises a density of at least about 140 kg/m 3 . 6. The multilayer composite of claim 1 , wherein the first porous layer comprises a silicon material content of at least about 30 wt. % and not greater than about 99 wt. % for a total weight of the first porous layer. 7. The multilayer composite of claim 1 , wherein the first porous layer comprises a filler material. 8. The multilayer composite of claim 7 , wherein the first porous layer comprises a filler material content of at least about 10 wt. % and not greater than about 90 wt. % for a total weight of the first porous layer. 9. The multilayer composite of claim 7 , wherein the filler material comprises mica kaolin. 10. The multilayer composite of claim 7 , wherein the filler material comprises alumina trihydrate (ATH, hydrated alumina), alumina monohydrate (boehmite), magnesium hydroxide (MDH) and other metal hydroxides. 11. A thermal barrier composite comprising: a first porous layer comprising a silicone material, and a first barrier layer overlying the first porous layer, wherein the first barrier layer comprises a polyaramid material, a polyimide material, or any combination thereof, wherein the thermal barrier composite comprises a flame resistance rating of at least about 200° C., and wherein the thermal barrier composite comprises a compression rating of not greater than about 350 kPa at 50% strain. 12. The thermal barrier composite of claim 11 , wherein the multilayer composite comprises a flame resistance rating of not greater than about 150° C. 13. The thermal barrier composite of claim 11 , wherein the composite comprises a 50% strain compression rating of not greater than about 400 kPa. 14. The thermal barrier composite of claim 11 , wherein the multilayer composite comprises a density of not greater than about 560 kg/m 3 . 15. The thermal barrier composite of claim 14 , wherein the multilayer composite comprises a density of at least about 140 kg/m 3 . 16. The thermal barrier composite of claim 11 , wherein the first porous layer comprises a silicon material content of at least about 30 wt. % and not greater than about 99 wt. % for a total weight of the first porous layer. 17. The thermal barrier composite of claim 11 , wherein the first porous layer comprises a filler material. 18. The thermal barrier composite of claim 11 , wherein the composite comprises a thickness ratio PL1/BL1 of at least about 2.0, where PL1 is equal to the thickness of the first porous layer and BL1 is equal to the thickness of the first barrier layer.
