US12498201 - Ballistic protective material for the reduction of impact trauma

A ballistic protective material, characterized in that it comprises a laminate made of aramid fabric having one or more layers of thermoplastic or thermosetting matrix. The resulting composite can be produced by using a film, by applying powders or resins; the material is very flexible, in the form of a roll having the desired width and length.

The patent describes a ballistic protective material made from a laminate of aramid fabric and a thermoplastic or thermosetting matrix designed to absorb energy and reduce impact trauma. This composite material is flexible, can be produced in roll form, and features an asymmetrical matrix applied to one side of the fabric, facing the projectile’s firing direction.

Claim 1

1 . A ballistic protective material for a ballistic solution comprising: a front section ( 3 ) of layers of material adapted for stopping a projectile, said front section ( 3 ) comprising a first layer element ( 2 ) having an impact surface for the projectile, a section ( 4 ) of layers ( 7 ) formed of a laminate made of material consisting of a base fabric ( 9 ) and a matrix ( 8 ) adapted for absorbing energy and impact trauma reduction, said matrix ( 8 ) including a thermoplastic or thermosetting resin having a chemical composition selected from the group consisting of: polyethylenes, polyurethanes, polypropylene, polyamide, polyester, polyarylester, polyvinyl butyral, polycarbonate, phenolic, epoxy, phenoxy, and acrylic resins, said matrix ( 8 ) being asymmetrical with respect to said base fabric ( 9 ) by being applied on one single side of said base fabric ( 9 ), and said matrix ( 8 ) facing a firing direction (F) of the projectile, said base fabric ( 9 ) is an aramid fabric with a plain weave, said aramid fabric having a linear density selected from the group consisting of 670 dtex, 940 dtex, 1100 dtex, 1320 dtex, 3140 dtex, and 3300 dtex, and said matrix ( 8 ) comprising 15 to 40% of a total weight of the laminate when the linear density of said aramid fabric is 3140 dtex or 3300 dtex, and said matrix ( 8 ) comprising 25 to 40% of the total weight of the laminate when the linear density of said aramid fabric is 670 dtex, 940 dtex, 1100 dtex, or 1320 dtex. a front section ( 3 ) of layers of material adapted for stopping a projectile, said front section ( 3 ) comprising a first layer element ( 2 ) having an impact surface for the projectile, a section ( 4 ) of layers ( 7 ) formed of a laminate made of material consisting of a base fabric ( 9 ) and a matrix ( 8 ) adapted for absorbing energy and impact trauma reduction, said matrix ( 8 ) including a thermoplastic or thermosetting resin having a chemical composition selected from the group consisting of: polyethylenes, polyurethanes, polypropylene, polyamide, polyester, polyarylester, polyvinyl butyral, polycarbonate, phenolic, epoxy, phenoxy, and acrylic resins, said matrix ( 8 ) being asymmetrical with respect to said base fabric ( 9 ) by being applied on one single side of said base fabric ( 9 ), and said matrix ( 8 ) facing a firing direction (F) of the projectile, said base fabric ( 9 ) is an aramid fabric with a plain weave, said aramid fabric having a linear density selected from the group consisting of 670 dtex, 940 dtex, 1100 dtex, 1320 dtex, 3140 dtex, and 3300 dtex, and said matrix ( 8 ) comprising 15 to 40% of a total weight of the laminate when the linear density of said aramid fabric is 3140 dtex or 3300 dtex, and said matrix ( 8 ) comprising 25 to 40% of the total weight of the laminate when the linear density of said aramid fabric is 670 dtex, 940 dtex, 1100 dtex, or 1320 dtex.
