Abstract

The present invention relates to a ballistic-resistant molded article comprising a consolidated stack comprising between 50 wt% and 95 wt% monolayers A and 5 wt% and at most 50 wt% monolayers B, the consolidated stack having an areal density of at least 7.0 and at most 15.0 kg/m², whereby the direction of orientation of two adjacent monolayers in the stack differs by at least 40 and up to 90 degree, wherein the monolayers A have an areal density of between 28 and 80 g/m² of the oriented polymer A and the monolayers B having an areal density of between 4 and 28 g/m² of the oriented polymer B, wherein the areal density of the oriented polymer A in the monolayers A is at least 5 g/m² higher than the areal density of the oriented polymer B in the monolayers B. The invention also relates to a hybrid ballistic-resistant molded article with a V50 when shot at an angle of 30° from perpendicular better than the V50 expected based on the individual V50 of the employed components. The invention further relates to a high performance ballistic-resistant sheet enabling the hybrid ballistic-resistant molded article.
