Assignee: TEIJIN ARAMID B.V.
Field: Surface technology, coating (Chemistry)
Classification: CPC F  B | IPC B  F

Claim 7:
8. A ballistic-resistant article comprising:
a stack of sheets, the sheets comprising at least two layers of ultra-high molecular weight polyethylene (UHMWPE) films provided with a continuous film of polymer as organic matrix material,
wherein the UHMWPE films are provided over at least 95% of at least one surface thereof with the continuous film of polymer as organic matrix material, the continuous film of polymer as organic matrix material not being an UHMWPE film,
wherein the UHMWPE films have a thickness of 10-100 microns and the organic matrix polymer film has a thickness of 0.1-3 microns,
wherein the weight percentage of the organic matrix polymer film with respect to the total weight of the organic matrix polymer film and the ultra-high molecular weight polyethylene films is from 0.1 to 3 wt. %,
wherein the sheets in the stack are consolidated, and
wherein an orientation of polymer molecules in the continuous film of polymer as organic matrix material in a first direction of the organic matrix polymer film differs from an orientation of polymer molecules in the continuous film of polymer as organic matrix material in a second direction of the organic matrix polymer film, wherein the first direction of the organic matrix polymer film and the second direction of the organic matrix polymer film are at an angle of 90°.
