Claim:
1. A multilayered material sheet comprising a consolidated stack of unidirectional monolayers produced from a plurality of drawn ultra high molecular weight polyolefin tapes, wherein a draw direction of two subsequent monolayers in the stack differs, and wherein an areal density of at least one monolayer is between 3 and 200 g/m 2 and an areal density of at least one drawn ultra high molecular weight polyolefin tape is between 10 and 80 g/m 2 , and wherein at least one monolayer of the stack has a strength which is at least 1.2 GPa, and wherein the plurality of drawn tapes are aligned in the same direction and adjacent ones of the tapes do not overlap.
