Zusammenfassung:The invention relates to an anti-ballistic molded article having an areal density of at least 7.0 kg/m2 and at most 12.0 kg/m2, said anti-ballistic molded article comprising a consolidated stack of fibrous monolayers, each fibrous monolayer comprising unidirectionally arranged high-toughness polyethylene filaments having a toughness of at least 3.5 N/tex, wherein the molded article comprises between 5.0% by weight and 20% by weight of a binder, and wherein the molded article comprises at least 330 of the fiber monolayers. The invention also relates to an anti-ballistic sheet suitable for producing said molded article, wherein each of the anti-ballistic sheets has an areal density of between 6 g/m2 and 30 g/m2 of the polyethylene filament monolayer present in the anti-ballistic sheet. The invention further relates to a ballistic resistant molded article having improved performance when shot at an angle of 30 degrees. 本发明涉及一种面密度为至少7.0kg/m2且至多12.0kg/m2的防弹模塑制品,所述防弹模塑制品包含纤维单层的固结堆叠,每个纤维单层含有单向排列的高韧度聚乙烯长丝,所述聚乙烯长丝的韧度为
