摘要:
The invention concerns a ballistic-resistant molded article having an areal density of at least 7.0 and at most 12.0 kg/m2, comprising a consolidated stack of fibrous monolayers, each fibrous monolayer containing unidirectionally aligned high tenacity polyethylene filaments, the polyethylene filaments having a tenacity of at least 3.5 N/tex, wherein the molded article comprises between 5.0 and 20 wt % of a binder, wherein the molded article comprises at least 330 of said fibrous monolayers. The invention also relates to a ballistic-resistant sheet suitable to manufacture the molded article, wherein said ballistic-resistant sheet has an areal density of between 6 and 30 g/m2 per polyethylene filament monolayer present in the ballistic-resistant sheet. The invention further relates to a ballistic-resistant molded article whit improved performance when shot under an angle of 30 degree.
