Abstract
Multilayer material sheets containing unidirectional high performance fibers are obtained by a process which includes 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 a 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 multilayer material sheet has a reduced uptake of liquids.
