Abstract

The invention relates to a process for the manufacture of a multilayer material sheet comprising unidirectional high performance fibers, the process comprising the steps of positioning the fibers in a parallel fashion, consolidation of the fibers to obtain a monolayer, stacking at least two monolayers such that the fiber direction in one monolayer is at an angle α to the direction of the fibers in an adjacent monolayer and fixation whereby the stack of at least two monolayers is subjected to a pressure and temperature treatment for a duration of a least 2 seconds, followed by cooling the stack under pressure to a temperature of 120° C. or lower. The invention furthermore relates to the multilayer material sheet obtainable with the process according to the invention. This multilayer material sheet has a reduced uptake of liquids.
