Abstract: Ballistic resistant sheets and molded articles formed thereof are disclosed, wherein a ballistic resistant sheet includes a stack of at least 4 monolayers, each monolayer containing unidirectionally oriented reinforcing fibers with a tensile strength of between 3.5 and 4.5 GPa, and at most 20 mass % of a matrix material, the areal density of a monolayer is at least 25 g/m2 and with the fiber direction in each monolayer being rotated with respect to the fiber direction in an adjacent monolayer. When a plurality of the ballistic resistant sheets are formed into a pile and subjected to curved molding conditions, a homogenous curved ballistic resistant molded article is formed without irregular folding of the ballistic resistant sheets in the pile.

Abstract: The invention relates to a material sheet comprising a woven fabric of polymer tapes, wherein the width of a tape varies less than 2% on average in the longitudinal direction of the tape. The invention also relates to a process for the preparation of the material sheet, and to a ballistic resistant article comprising the material sheet. A ballistic resistant article comprising the material sheet exhibits excellent antiballistic properties.

Abstract: The invention relates to a ballistic resistant sheet comprising a stack of at least 4 monolayers, each monolayer containing unidirectionally oriented reinforcing fibres with a tensile strength of between 3.5 and 4.5 GPa, and at most 20 mass % of a matrix material, the areal density of a monolayer is at least 25 g/m2 and with the fibre direction in each monolayer being rotated with respect to the fibre direction in an adjacent monolayer. The invention further relates to a ballistic resistant moulded article, i.e. a shaped part, comprising at least two ballistic resistant sheets according to the invention, which may be used as, for example, a panel for use in e.g. a vehicle, especially a curved panel, a hard insert e.g. for use in protective clothing and bullet resistant vests, etc. The ballistic resistant moulded article optionally may have a ceramic or a metal strike face.

Abstract: The invention relates to a stack comprising a consolidated stack of first and second layers. The first layers comprise drawn polymeric fibers and optionally a binder, and the second layers comprise drawn polymeric tapes. The invention also relates to a panel comprising a consolidated stack and to a ballistic resistant article comprising the stack or the panel.
