  • BALLISTIC-RESISTANT MOULDED ARTICLE AND PROCESS FOR OBTAINING SUCH ARTICLE
    Publication number: 20100170021
    Abstract: The invention relates to a process for the manufacture of a moulded article comprising the steps of forming a stack by stacking (2) or more sheets comprising monolayers of unidirectional fibers and optionally a binder; providing isostatic pressurizing means; placing the stack in the isostatic pressurizing means; and consolidating the stack under temperature and isostatic pressure into a moulded article. The invention furthermore relates to products obtainable with said process, which are very suitable for use in anti-ballistic applications and include e.g. helmets, curved panels, cones and domes.
