Abstract
A lightweight ballistic resistant materials and method of making the same are provided. The material includes at least two layers of penetration resistant material intermittently connected to form areas of connection between the material and much larger areas of material where there is no connection between the adjacent layers. The intermittently connected material may be used as a component of composite ballistic panels or may be utilized alone to provide penetration protection.
Claims14
A composite ballistic panel, comprising:
- a first ballistic panel, comprising:
- a at least one first layer formed of a woven ballistic resistant material;
- at least one second layer formed of a non-woven ballistic resistant material;
- a first series of connectors intermittently joining said at least one first layer and said at least one second layer;
- and
- a second series of connectors intermittently joining said at least one first layer and said at least one second layer;
- wherein the first and second series of connectors define unconnected areas of material having a cumulative surface area substantially larger than the cumulative surface area of the connected material;
- a second ballistic panel, comprising:
- at least one first layer formed of a woven ballistic resistant material;
- at least one second layer formed of a non-woven ballistic resistant material;
- a first series of connectors intermittently joining said at least one first layer and said at least one second layer;
- and
- a second series of connectors intermittently joining said at least one first layer and said at least one second layer;
- wherein the first and second series of connectors define unconnected areas of material having a cumulative surface area substantially larger than the cumulative surface area of the connected material;
- and
- a hard coupon, comprising:
- a first layer formed of a ballistic resistant material;
- and
- a second layer formed of a ballistic resistant material;
- wherein said first layer and said second layers are joined together via a laminate.

A method for making a lightweight, composite ballistic panel, comprising the steps of:
- providing a first ballistic panel, comprising the steps of:
- aligning at least one layer formed of a woven ballistic resistant material and at least one layer formed of a non-woven ballistic resistant material in a stacked configuration;
- and
- interconnecting a small portion of the layers while leaving a substantially larger portion of the layers unconnected;
- providing a second ballistic panel, comprising the steps of:
- aligning at least one layer formed of a woven ballistic resistant material and at least one layer formed of a non-woven ballistic resistant material in a stacked configuration;
- and
- interconnecting a small portion of the layers while leaving a substantially larger portion of the layers unconnected;
- providing a hard coupon formed of laminated layers of ballistic resistant material;
- and
- aligning the hard coupon with the first and second ballistic panels in a stacked configuration.
