Abstract
A ballistic panel is described including a core layer having a first major surface and a second major surface, the core layer including a ballistic gel. The first layer of ballistic resistant material is on the first major surface of the core layer. A second layer of ballistic resistant material is on the second major surface of the core layer.
Claims31
A ballistic panel, comprising:
- a core layer having a first major surface and a second major surface, the core layer comprising a ballistic gel, the ballistic gel comprising polyurethane and polyborodimethylsiloxane (PBDMS);
- a first layer of ballistic resistant material on the first major surface of the core layer;
- a second layer of ballistic resistant material on the second major surface of the core layer;
- a first face sheet on the first layer of ballistic resistant material;
- and
- a second face sheet on the second layer of ballistic resistant material,
- wherein the first layer of ballistic resistant material and the second layer of ballistic resistant material comprise para-aramid fibers impregnated with a cured resin, comprising a resin selected from the group consisting of benzoxazine, polyether ether ketone (PEEK), polyetherketoneketone (PEKK), polyphenylsulfone (PPSU), polyphenylene sulfide (PPS), and polyetherimide (PEI).

A method of making a ballistic panel, the method comprising:
- providing a core layer having a first major surface and a second major surface, the core layer comprising a ballistic gel, the ballistic gel comprising polyurethane and polyborodimethylsiloxane (PBDMS);
- attaching a first layer of ballistic resistant material on the first major surface of the core layer;
- attaching a second layer of ballistic resistant material on the second major surface of the core layer;
- attaching a first face sheet on the first layer of ballistic resistant material;
- and
- attaching a second face sheet on the second layer of ballistic resistant material,
- wherein the first layer of ballistic resistant material and the second layer of ballistic resistant material comprise para-aramid fibers impregnated with a cured or curable resin,
- wherein the cured or curable resin is selected from the group consisting of benzoxazine, polyether ether ketone (PEEK), polyetherketoneketone (PEKK), polyphenylsulfone (PPSU), polyphenylene sulfide (PPS), and polyetherimide (PEI).
