Abstract
The invention relates to a ballistic-resistant molded article containing a compressed stack of monolayers, with each monolayer containing unidirectionally oriented reinforcing fibers and at most 30 wt. % of a plastic matrix material and with the fiber direction in each monolayer being rotated with respect to the fiber direction in an adjacent monolayer, characterized in that the density (.rho..sub.P) of the compressed stack is at least 98.0% of the theoretical maximum density. The invention also relates to a process for manufacturing the molded article. The ballistic-resistant article may be used in, for instance, helmets, as inserts in bullet-proof vests, as armoring on military vehicles and in ballistic-resistant panels.
