Abstract[English]
The present invention relates to a blend comprising as components 85 to 68 wt.% of at least one polyarylene ether sulfone polymer (P1) with a viscosity number (VN) between 45 to 58 ml/g, and at least one phenoxy polymer (P2). Another aspect of the present invention is a film and a granulate made from the blend, and a sandwich panel comprising an upper top layer (UTL) comprising a polyarylene ether sulfone polymer and a fiber reinforcement, a foam core layer (FCL) comprising a polyarylene ether sulfone polymer, and a lower top layer (LTL) comprising a polyarylene ether sulfone polymer and a fiber reinforcement, wherein the upper top layer (UTL) is joined with the foam core layer (FCL) via a first film (F1) made from the blend, and wherein the lower top layer (LTL) is joined with the foam core layer (FCL) via a second film (F2) made from the blend. Another aspect of the present invention is a process to produce the sandwich panel, and the use of the sandwich panel as construction parts for aviation industry, or for the construction of rotor blades for wind turbines. Yet another aspect of the present invention is a process for the re-use of the sandwich panel, and the use of the blend as an adhesive layer.[French]
La présente invention concerne un mélange comprenant en tant que composants de 85 à 68% en poids d'au moins un polymère de polyarylène éther sulfone (P1) ayant un nombre de viscosité (VN) compris entre 45 et 58 ml/g, et au moins un polymère phénoxy (P2). Un autre aspect de la présente invention est un film et un granulé fabriqué à partir du mélange, et un panneau sandwich comprenant une couche supérieure supérieure (UTL) comprenant un polymère de polyarylène éther sulfone et un renfort fibreux, une couche centrale en mousse (FCL) comprenant un polymère de polyarylène éther sulfone, et une couche supérieure inférieure (LTL) comprenant un polymère de polyarylène éther sulfone et un renfort fibreux, la couche supérieure supérieure (UTL) étant jointe à la couche centrale en mousse (FCL) par l'intermédiaire d'un premier film (F1) fabriqué à partir du mélange, et la couche supérieure inférieure (LTL) étant jointe à la couche centrale en mousse (FCL) par l'intermédiaire d'un second film (F2) fabriqué à partir du mélange. Un autre aspect de la présente invention concerne un processus de production du panneau sandwich, et l'utilisation du panneau sandwich en tant que pièces de construction pour l'industrie aéronautique, ou pour la construction de pales de rotor pour éoliennes. Encore un autre aspect de la présente invention concerne un processus de réutilisation du panneau sandwich, et l'utilisation du mélange en tant que couche adhésive.
