Balistic-resistant moulded article and a process for the manufacture of the moulded article

A process for manufacturing a ballistic resistant moulded article containing a compressed stack of monolayers, with each monolayer containing unidirectionally oriented reinforcing fibres and at most 30 wt. % of a plasctic matrix material in which a stack is made of crosswise-arranged monolayers, which stack is compressed under pressure of at least 5 MPa and at an elevated temperature and which stack is thereafter cooled under pressure, wherein the monolayers have a fiber weight between 25 and 100 gr/m2 and the density (ρp) of the compressed stack is at least 98.0% of the theoretical maximum density.

A process for manufacturing a ballistic resistant moulded article in which in a first step a semi-manufactured article is produced by forming a stack of cross-layered monolayers, each monolayer containing unidirectionally oriented reinforcing fibers and at most 30 wt. % of a plastic matrix material, which stack has an areal weight of from 0.25 to 5 kg/m2, and subsequently compressing this stack at an elevated temperature and cooling this stack at a given first compressive pressure wherein, in a second step, one or more of the semi-manufactured articles produced in the first step are compressed onto each other at an elevated temperature and cooled at a given second pressure, with the first pressure being at least 5 MPa to a compressed stack density (ρp) which is at least 98.0% of the theoretical maximum density.
