Title
(EN) A METHOD OF MANUFACTURING A COMPOSITE ELEMENT HAVING IMPROVED RESISTANCE TO DELAMINATION AND ACOMPOSITE ELEMENT OBTAINED THEREWITH
(FR) PROCÉDÉ DE FABRICATION D'UN ÉLÉMENT COMPOSITE AYANT UNE RÉSISTANCE AMÉLIORÉE AU DÉLAMINAGE ET ÉLÉMENT COMPOSITE OBTENU À PARTIR DE CELUI-CI
Abstract
(EN) The invention provides a method of manufacturing a composite element having improved resistance to delamination, the composite element comprising a first thermoplastic polymer layer a) and a second thermoplastic polymer layer b), wherein a boundary surface of the first thermoplastic polymer layer a) is chemically crosslinked with a boundary surface of the thermoplastic polymer layer (b). The composition for the crosslinking comprises: c1) a thermoplastic polymer and c2) a monomer or oligomer having at least two reactive functional groups selected for reactivity with the functional groups on the thermoplastic polymer boundary surfaces. The invention also provides a composite element which can be obtained by the process. It is further provided that the composite element may be used as a wall in a transport vehicle, a wind turbine, a storage area, or a packaging container.
(FR) L'invention concerne un procédé de fabrication d'un élément composite ayant une résistance améliorée au délaminage, l'élément composite comprenant une première couche de polymère thermoplastique a) et une seconde couche de polymère thermoplastique b), une surface limite de la première couche de polymère thermoplastique a) étant réticulée chimiquement avec une surface limite de la couche de polymère thermoplastique (b). La composition pour la réticulation comprend : c1) un polymère thermoplastique et c2) un monomère ou oligomère ayant au moins deux groupes fonctionnels réactifs choisis pour une réactivité avec les groupes fonctionnels sur les surfaces limites de polymère thermoplastique. L'invention concerne également un élément composite qui peut être obtenu par le procédé. En outre, l'élément composite peut être utilisé comme paroi dans un véhicule de transport, une éolienne, une zone de stockage ou un récipient d'emballage.
