Title (EN) FIBRE REINFORCEMENT OF REACTIVE FOAMS OBTAINED BY A MOULDING FOAM METHOD
(FR) RENFORCEMENT PAR FIBRES DE MOUSSES RÉACTIVES OBTENUES PAR UN PROCÉDÉ DE MOULAGE EN FORME
(DE) FASERVERSTÄRKUNG VON REAKTIVSCHAUMSTOFFEN AUS EINEM FORMSCHÄUMVERFAHREN
Abstract:
(EN) The present invention relates to a moulded body made of a reactive foam material, at least one fiber (F) being located partly within the moulded body, i.e. being surrounded by the foam material. The two ends of the respective fiber (F) which are not surrounded by the reactive foam material thus protrude on one side of the corresponding moulded body. The reactive foam material is produced according to moulding foam method. The invention also relates to a panel which comprises at least one such moulded body and at least one additional layer (S1). The invention further relates to methods for the production of the moulded bodies from reactive foam material or to the panels according to the invention and to the use thereof, for example as rotor blades in wind turbines.
(FR) La présente invention concerne un corps moulé en mousse réactive, au moins une fibre (F) se trouvant à l'intérieur du corps moulé, et donc étant entourée de la mousse réactive. Les deux extrémités, non entourées de mousse, de la fibre (F) respective émergent respectivement d'un côté du corps moulé correspondant. La mousse réactive est fabriquée par un procédé de moulage en forme. La présente invention concerne également un panneau qui comporte au moins un tel corps moulé et au moins une autre couche (S1). En outre, la présente invention concerne des procédés de fabrication des corps moulés en mousse réactive selon l'invention ou des panneaux selon l'invention, ainsi que leur utilisation, par exemple comme pale de rotor dans des éoliennes.
(DE) Die vorliegende Erfindung betrifft einen Formkörper aus Reaktivschaumstoff, wobei sich mindestens eine Faser (F) teilweise innerhalb des Formkörpers befindet, also vom Reaktivschaumstoff umschlossen ist. Die beiden nicht vom Reaktivschaumstoff umschlossenen Enden der jeweiligen Faser (F) ragen somit aus jeweils einer Seite des entsprechenden Formkörpers heraus. Der Reaktivschaumstoff wird durch ein Formschäumverfahren hergestellt. Ein weiterer Gegenstand der vorliegenden Erfindung ist ein Paneel, das mindestens einen solchen Formkörper sowie mindestens eine weitere Schicht (S1) umfasst. Weitere Gegenstände der vorliegenden Erfindung sind Verfahren zur Herstellung der erfindungsgemäßen Formkörper aus Reaktivschaumstoff bzw. der erfindungsgemäßen Paneele sowie deren Verwendung, beispielsweise als Rotorblatt in Windenergieanlagen.
