The invention relates to a process for the manufacture of a shaped part comprising the steps of&#x2014;forming a stack by stacking (2) or more sheets comprising mono-layers of unidirectional anti-ballistic fibers and a binder followed by placing the stack in a mould, clamping the stack in the mould with a control member closing the mould&#x2014;consolidating the stack under temperature and pressure into a curved shaped part. 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.
