摘要:
The invention relates to a process for manufacturing a curved product, wherein the process comprises positioning a plurality of drawn polymeric reinforcing elements onto a mandrel, locally adhering at least a part of the elements to each other, and removing the product from the mandrel. The invention also relates to a process for manufacturing a curved article, preferably an armour article, from the curved product, the process comprising positioning the curved product in a mould and compressing said product at an elevated temperature and pressure. The curved armour article has good antiballistic properties and is substantially free of wrinkles.

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. The ballistic resistant moulded article according to the invention offers protection against ballistic impacts such as bullets and ballistic fragments.
