Patent ID: 8329084

Claim:
A process for the manufacture of a shaped part comprising the steps of: forming a stack by stacking 2 or more sheets comprising mono-layers, said mono-layers comprising unidirectional anti-ballistic fibers and a binder which holds the fibers together, wherein the fibers have a tensile strength of at least about 1.2 GPa and a tensile modulus of at least 40 GPa, whereby in the stack the direction of the anti-ballistic fiber in the sheets comprising mono-layers of unidirectional anti-ballistic fibers and a binder is at an angle α to the fiber direction in an adjacent mono-layer, followed by placing the stack in a mould, clamping the stack in the mould with a control member such that the stack can slip and move during the closing of the mould, closing the mould, and consolidating the stack under temperature and pressure into a curved shaped part.
