MULTIAXIAL STACK RIGIDLY CONNECTED BY MEANS OF WELD POINTS APPLIED BY MEANS OF INSERTED THERMOPLASTIC WEBS

摘要

The present invention relates to a stack of fibrous materials including at least two unidirectional carbon fibre layers, each extending in different directions, wherein each one of the unidirectional layers is connected by means of at least one of the surfaces thereof to an adjacent web of thermoplastic fibres, at least one web being inserted between two consecutive unidirectional layers, characterised in that the link between each unidirectional layer and each adjacent web is provided by the web, by weld points which produce an intermittent overall weld, and in that said weld points also guarantee the cohesion of the stack, as well as the method for manufacturing same.
