Abstract
A panel had a first face and a second face, including a strike face portion having a first plurality of plies each containing fibers in a matrix material. There is a support portion adjacent to the strike face portion, the support portion containing a second plurality of plies each having fibers in a matrix material. 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 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.
Claims11
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.
