US12352535 - Impact resistant material

The patent describes an impact-resistant ballistic protection material created from a melanin composite combined with polyvinyl alcohol and other additives. This material is processed through a specific mixing and compression method to produce various forms such as slabs, plates, and bricks for effective ballistic and blast protection.

Claim 1

1. A ballistic protection material formed using a composition comprising: melanin material which has been dried in a microwave to form dried melanin material, and polyvinyl alcohol, methylparaben and propylparaben; mixing the dried melanin material and polyvinyl alcohol at a ratio of about 40 to about 60 to about 50 to about 50 (percent by weight) to form a mixture; compressing the mixture, wherein the compression is applied in a hydraulic press wherein the hydraulic press ranges in capacity from approximately 1 ton/in 2 to approximately 50 tons/in 2 , thereby forming the ballistic protection material, wherein the ballistic protection material is manufactured in a form selected from the group consisting of slabs, plates, and bricks. melanin material which has been dried in a microwave to form dried melanin material, and polyvinyl alcohol, methylparaben and propylparaben; mixing the dried melanin material and polyvinyl alcohol at a ratio of about 40 to about 60 to about 50 to about 50 (percent by weight) to form a mixture; compressing the mixture, wherein the compression is applied in a hydraulic press wherein the hydraulic press ranges in capacity from approximately 1 ton/in 2 to approximately 50 tons/in 2 , thereby forming the ballistic protection material, wherein the ballistic protection material is manufactured in a form selected from the group consisting of slabs, plates, and bricks.
