Abstract

The invention pertains to a ballistic resistant moulded article comprising a compressed stack of sheets comprising high molecular weight polyethylene tapes the direction of the polyethylene tapes within the compressed stack being not unidirectionally wherein at least part of the tapes have a width of at least 2 mm and a thickness to width ratio of at least 10:1 and a density of at most 99% of the theoretical tape density. The moulded article is based on tapes which have a density below the theoretical density of the tapes. The use of low density tapes is believed to contribute to the ballistic performance of the panel.
