Abstract

A panel had a first face and a second face, including a strike face portion (22) having a first plurality of plies each containing fibers in a matrix material (26). There is a support portion (28) adjacent to the strike face portion (22), the support portion (28) containing a second plurality of plies each having fibers in a matrix material (36). Each ply is bound to an adjacent ply and the first fibers are lower- performing relative to the second fibers. Protection from a ballistic threat may be provided by providing such a panel with the strike face (23) disposed toward the threat. In another aspect, a composite ballistic panel may contain fibers in a thermoplastic matrix material, to the substantial exclusion of thermosetting matrix materials.

Claims

AMENDED CLAIMS received by the International Bureau on 01 December 2008
1. A panel having a first face and a second face and comprising: a strike face portion comprising a first plurality of plies each comprising E-glass fibers in a first polyolefin matrix material; and a support portion adjacent to the strike face portion, the support portion comprising a second plurality of plies each comprising S-glass fibers in a second polyolefin matrix material, wherein each ply is bound to an adjacent ply and wherein the first fibers are lower- performing relative to the second fibers.
2. The panel of claim 1 , wherein the panel achieves at least one of the protection levels against a projectile as defined by NIJ Standard Armor grades H-A, II, IH-A, III, and IV when the projectile is directed at the strike face.
3. The panel of claim 1 wherein the fibers that are substantially parallel to each other within their respective plies and wherein the plies are disposed so that fibers of each ply are disposed cross-wise to fibers of an adjacent ply.
4. The panel of claim 1, wherein the fibers that are substantially parallel to each other within their respective plies and wherein the plies are disposed so that fibers of each ply are disposed cross-wise to fibers of an adjacent ply, and wherein the panel achieves at least one of the protection levels against a projectile as defined by NIJ Standard Armor grades H-A, II, HI-A, HI, and FV when the low-performing fibers are at the strike face.
5. The panel of claim 4, wherein the first polyolefin matrix material and the second polyolefin matrix material both comprise polypropylene.
6. The panel of claim 1 , wherein the first polyolefin matrix material and the second polyolefin matrix material both comprise polypropylene.
7. The panel of claim 1 , having an area! weight of about 1 to about 10 pounds per square foot.
8. The panel of claim 4, having an areal weight of about 1 to about 10 pounds per square foot.
9. The panel of claim 6, having an areal weight of about 1 to about 10 pounds per square foot.
10. (canceled)
1 1. (canceled)
12. A method of providing protection against a ballistic threat, comprising providing a panel according to claim 1 and disposing the panel with the strike face towards the threat.
13. (canceled)
