Image unavailable

The present disclosure is direct to a soft body armor assembly that comprises a first subpanel and a second subpanel. The first subpanel may have a first portion and a second portion. The first portion may have a first plurality of ultra-high molecular weight polyethylene fiber sheets. Each sheet of the first plurality may have two single layers of unidirectional sheets cross plied at 90 degrees to one another. The second portion may have a second plurality of ultra-high molecular weight polyethylene fiber sheets. The second subpanel may comprise a third portion and a fourth portion. The third portion may have a third plurality of ultra-high molecular weight polyethylene fiber sheets. The fourth portion may have one or more composite sheets.

The patent describes a soft body armor assembly consisting of two subpanels, each made from ultra-high molecular weight polyethylene fiber sheets arranged in a specific cross-plied configuration for enhanced protection. The assembly features multiple portions with stitched perimeters, allowing for a layered construction that combines both polyethylene and composite materials.

Claim 1
