International Classification:

B32B 27/28
F41H 7/00
B32B 27/08

US Classification:

89 3602, 4284231, 428 76

Abstract:

A polymeric coating composition for use in overlaying at least a portion of a substrate element composed of a plural component polymeric system composed of a reactive blend of at least one first component and at least one second component, wherein the first component is consists essentially of a polymer and/or a blend of polymers present in an amount sufficient to impart a predetermined amount of tensile strength, hardness, flexibility and adhesive strength to the resulting polymeric coating and the second component is an isocyanate or isocyanate quasi-prepolymer. The substrate element is a blast-resistant polymeric material having low surface energy and/or low reactivity at or near the surface of the substrate. Also disclosed is a blast and/or ballistic-resistant construction element composed of a structure having the aforementioned polymeric material in overlying attached relationship thereto. The polymeric material of the structure has a substrate matrix containing at least one of ultrahigh molecular weight polyethylene, aramid materials, and the like.

Inventors:

- Stratford CT, US
Shawn D. Alexander - Battle Ground WA, US

International Classification:

F41H 5/04

Abstract:

An item of armor includes a ballistics arresting core, a first shell layer disposed on a first side of the ballistics arresting core, and a second shell layer disposed on a second side of the ballistics arresting core such that the second shell layer partially overlaps the first shell layer at an edge of the first shell layer to seal the ballistics arresting core within the first shell layer and the second shell layer.

Appl. No.:

15/428904

Inventors:

- Stratford CT, US
Shawn Alexander - Battle Ground WA, US

International Classification:

F41H 5/04

Abstract:

A method for manufacturing armor includes coating a first side of a ballistics arresting core with a first shell layer to create a partially coated ballistics arresting core, placing the partially coated ballistics arresting core in a vacuum bag and depressurizing the vacuum bag and curing the partially coated ballistics arresting core in the depressurized vacuum bag to create a partially shelled ballistics arresting core. The method further includes removing the partially shelled ballistics arresting core from the vacuum bag, coating a second side of the partially shelled ballistics arresting core with a second shell layer to create a fully coated ballistics arresting core, placing the fully coated ballistics arresting core in a vacuum bag and depressurizing the vacuum bag, and curing the fully coated ballistics arresting core in the depressurized vacuum bag to create a fully shelled ballistics arresting core.
