Abstract
Official abstract text for this publication.
This invention pertains to a ballistic resistant article comprising at least one first layer facing a projectile and at least one second layer adjacent to the at least one first layer and facing an object to be protected wherein, under a ballistic event, the at least one first layer is capable of undergoing a shock induced non-reversible phase transformation.
First claim
Opening claim text (preview).
What is claimed is: 1. A ballistic resistant article comprising at least one first layer facing a projectile and at least one second layer adjacent to the at least one first layer and facing an object to be protected wherein the at least one first layer comprises hBN. 2. The article of claim 1 wherein the at least one second layer comprises metal, ceramic, fibrous yarn or polymeric tape, the fibrous yarn or polymeric tape having a tenacity of at least 10 g/dtex (9 g/denier). 3. The article of claim 1 wherein the thickness of the at least one first layer is from 0.1 to 75 mm. 4. The article of claim 3 wherein the thickness of the at least one first layer is from 0.1 to 5 mm. 5. The article of claim 1 wherein the at least one first layer comprises a blend of non-reversible phase transformable material and a thermoset or thermoplastic polymeric resin wherein the polymer comprises up to 85 weight percent of the blend. 6. The article of claim 1 optionally comprising at least one third layer, the third layer being adjacent to the at least one second layer and facing an object to be protected wherein the at least one third layer comprises filaments of aromatic polyamide, aromatic copolyamide, ultra high molecular weight polyethylene (UHMWPE), polyazole, glass or non-filamentary UHMWPE tape. 7. The article of claim 1 optionally comprising a multi-hit protection fourth layer positioned in front of the first layer. 8. The article of claim 7 comprising a non-ballistic energy impact protection layer positioned in front of the fourth layer. 9. The article of claim 1 comprising a non-ballistic energy impact protection layer positioned in front of the at least one first layer.
