Flameproof material for wearables, personal protective equipment, lithium-ion battery flame protection, and general flame protection
Flameproof material for wearables, personal protective equipment, lithium-ion battery flame protection, and general flame protection are disclosed. A particular embodiment includes a flameproof material comprising: a first material being a combination of Oxidized Polyacrylonitrile (PAN) fiber and Para-aromatic polyamide (P-aramid) fiber; a second material being a combination of Oxidized PAN fiber, fire-resistant rayon (FR-rayon), and P-aramid fiber; and a third material being a combination of silica aerogel and fibrous glass configured for bonding with the first or second materials, the second material being configured for bonding with the first or third materials.
1 . A flameproof material comprising:
a first material comprising a combination of Oxidized Polyacrylonitrile (PAN) fiber and Para-aromatic polyamide (P-aramid) fiber, wherein the first material is woven into a first layer;
a second material comprising a combination of Oxidized PAN fiber, fire-resistant rayon (FR-rayon), and P-aramid fiber, wherein the second material is woven into a second layer; and
a third material comprising a combination of silica aerogel and fibrous glass,
wherein the first material is disposed coextensive across substantially an entire first planar area over a plane of the second material,
wherein the third material is disposed coextensive across substantially an entire second planar area under a plane of the second material,
wherein the first layer, second layer, and third layer define generally parallel, planar interfaces that are bonded together across the entire first planar area and the second planar area by at least one of adhesive bonding or compression in a z-direction.
2 . The flameproof material of claim 1 , further comprising a fourth material comprising a combination of Oxidized PAN fiber and P-aramid fiber in a composition different from the first material, the fourth material disposed coextensive across substantially an entire planar area under a plane of the second material, the fourth material being a discrete sheet bonded to the second layer across the entire second planar area.
3 . The flameproof material of claim 2 , further including a fifth material comprising a moisture-wicking fiber, the fifth material disposed coextensive across substantially a fourth entire planar area under a plane of the third material, the fifth material being a discrete sheet.
4 . The flameproof material of claim 2 , wherein the second material is coupled to the fourth material and wherein the third material is coupled to the fourth material.
5 . The flameproof material of claim 4 , wherein the second material is coupled to the fourth material by at least one of bonding with adhesive or linking with a thread.
6 . The flameproof material of claim 2 , further comprising a sixth material, the sixth material disposed at least partially coextensive under a plane of the third material, the sixth material comprising an aerogel, wherein the sixth material is bonded to the third material.
7 . The flameproof material of claim 6 , wherein the sixth material comprises amorphous magnesium-silicate wool.
8 . The flameproof material of claim 1 , wherein the third material includes iron oxide and aluminum trihydrate.
9 . The flameproof material of claim 1 , wherein the second material is coupled to the third material.
10 . The flameproof material of claim 1 , wherein the first material is coupled to the second material by bonding with adhesive applied as a film between across the first coextensive area.
11 . The flameproof material of claim 1 , wherein the first material is coupled to the second material by linking with a thread.
12 . The flameproof material of claim 1 , wherein the first material includes at least 50% Oxidized PAN fiber.
13 . The flameproof material of claim 1 , wherein the first material includes at least 15% P-aramid fiber.
14 . The flameproof material of claim 1 wherein the second material includes at least 20% FR-rayon.
15 . The flameproof material of claim 1 , wherein the third material includes at least 30% amorphous silica and at least 40% fibrous glass.
16 . The flameproof material of claim 15 , wherein the third material comprises a porosity from 80%-99%, wherein the third material comprises an aerogel blanket having a thickness between 0.1 mm and 5 cm.
