Abstract

See full text

The invention relates to a composite sheet comprising at least two adjacent fibrous monolayers of unidirectionally aligned high tenacity polyethylene fibers, whereby the direction of orientation between the polyethylene fibers of said two fibrous layers differs by at least 80° and up to 90°, the fibers having a tenacity of at least 1.5 N/tex, said fibers being in a matrix comprising a homopolymer or copolymer of ethylene and wherein said homopolymer or copolymer of ethylene has a density as measured according to IS01183 of between 870 to 980 kg/m3, said composite sheet having an areal density of between 50 and 500 g/m2 wherein the composite sheet has an areal density normalized in-plane shear force measured at 25° C. evaluated according to the bias extension test method of at least 0.40 N·m2·g-1 at 10 mm clamp displacement.
