Fire resistant barrier laminates and articles made therefrom

1. An article comprising

a first laminate panel and a second laminate panel, each said laminate panel comprising

at least one liquidproof barrier layer,

a first fire resistant woven textile layer comprising meta-aramid, para-aramid, PBI, PBO, or blends thereof having a weight of less than or equal to 7 ounces per square yard bonded to a side of the at least one liquidproof barrier, and

a second fire resistant woven textile layer bonded to a side of the at least one liquidproof barrier layer opposite the first fire resistant woven textile layer to form the first and second laminate panels, said second fire resistant woven textile layer consisting essentially of woven yarns comprised of meta-aramid, para-aramid, PBI, PBO, or blends thereof having a weight of about 2.5 ounces per square yard or less; and

at least one liquidproof seam joining together the at least two laminate panels comprising a seam tape that covers a seam and bonds to the second woven textile layers of the first and second laminate panels,

wherein the first laminate panel and the second laminate panel are flame resistant forming a char length of less than 100 mm when subjected to a vertical flame test.

2. The article of claim 1 , wherein the barrier layer comprises a selectively permeable chemical protective layer.

3. An article comprising

a first laminate panel and a second laminate panel, each said laminate panel comprising at least one liquidproof barrier layer and at least one fire resistant woven textile layer bonded to the at least one barrier layer to form the first and second laminate panels, said textile comprising meta-aramid, para-aramid, PBI, PBO, or blends thereof having a weight of about 2.5 ounces per square yard or less, wherein the first and second laminate panels are joined together by a sewn seam; and

a seam tape that covers the sewn seam and bonds to the at least one woven textile layers of the first and second laminate panels to form

at least one liquidproof seam joining together the at least two laminate panels.

4. The article of claim 3 , wherein the article further comprises a seam edge and the seam edge is folded onto at least one fire resistant woven textile layer of either the first or second laminate panel, and the seam tape covers the sewn seam and the seam edge and bonds to the at least one woven textile layers of the first and second laminate panels to form at least one liquidproof seam.

5. The article of claim 3 , wherein the at least one barrier layer comprises a selectively permeable chemical protective layer.

6. The article of claim 3 , wherein the textile of the at least one fire resistant woven textile layer comprises meta-aramid and para-aramid fibers.

7. The article of claim 3 , wherein the barrier layer comprises a plurality of layers.

8. The article of claim 3 , wherein said at least one first fire resistant woven textile layer has a weight of about 0.9 to 2.5 ounces per square yard.

9. The article of claim 3 , wherein said at least one first fire resistant woven textile layer has a weight of about 1 to 2 ounces per square yard.

10. The article of claim 3 , wherein said at least one first fire resistant woven textile layer has a weight of about 1.6 to 1.8 ounces per square yard.

11. The article of claim 3 , wherein the at least one first fire resistant woven textile layer has a cover factor of about 1800 or less.

12. The article of claim 3 , wherein the at least one first fire resistant woven textile layer has a cover factor of about 1400 or less.
