Abstract:
This patent application focuses on the cutting, laying and impregnating the fiber tape using a tape laying and cutting head. The head contains a stationary or moving laser system with an in- situ mixing of resin and hardener, rollers (1,2) and a spreader (6) for pressing. The head enables manufacturing of small fiber reinforced parts avoiding the problems in manufacturing them.
Abstract:
La présente invention concerne une tête d'application de fibres et un procédé d'application de fibres pour la réalisation de pièces en matériau composite, la tête comprenant des moyens de coupe aptes à couper les fibres et, des moyens de réacheminement comprenant au moins un galet d'entraînement (105) motorisé et un contre- galet actionné par un système d'actionnement entre une position de repos et une position de réacheminement pour pincer au moins une fibre entre le galet d'entraînement et le contre-galet. Ledit galet d'entraînement comprend un noyau (106) couplé à un moteur, une couronne (107) montée mobile angulairement sur ledit noyau entre une position initiale, et une position d'entraînement dans laquelle le noyau entraîne positivement en rotation la couronne, et des moyens de sollicitation (109) appliquant un effort de rappel pour solliciter la couronne vers sa position initiale.
Abstract:
The invention relates to a laying die (12) for picking up and laying of substrates, the die comprising an elastically deformable substrate receiving structure (26) for providing an engagement surface (86) for releasable receiving of substrates, an attaching element (22) comprising a gas channel (46) for providing positively or negatively pressurized gas (45) for picking up and blowing off the substrates, a carrier body (24) made from an elastically deformable material, the carrier body being sandwiched between the receiving structure and the attaching element, wherein the attaching element is arranged to distribute the gas over the carrier body, wherein the carrier body comprises a plurality of breakthroughs (34) to transfer the gas from the attaching element to the receiving structure, wherein the receiving structure comprises an elastically deformable distribution plate (70) to distribute the gas over the engagement surface.
Abstract:
A method of manufacturing a wind turbine blade shell part is described. Fibre mats and a root end insert are laid up in a mould part in a layup procedure by use of an automated layup system. The fibre mats are laid up by use of a buffer roller (38) so that the fibre mats (24) may continuously be laid up on the mould surface, also during a cutting procedure. The root end insert is prepared in advance and mounted on a mounting plate. The root end insert is lowered onto the mould by use of the mounting plate and a lowering mechanism. After the wind turbine blade shell has been moulded, the mounting plate is removed.

Abstract:
A method of manufacturing a fibre-composite article is described, wherein a layer of fibre material is applied from a layup head (16) to a mould (10) along a layup path (12). The angle at which the fibre material is dispensed from the layup head (16) is rotated relative to the angle of orientation of the layup path (12), to minimise the effects of gravity on the alignment of the fibre layer in the mould (10). The fibre-composite article is preferably a section of a blade for a wind turbine.
Abstract:
The present invention is directed to a pneumatically actuated redirection surface guide tool for use in tape laying systems. In the laying of unidirectional, pre-impregnated carbon fiber tapes, for instance, a tape can be directed between a tape supply reel and a tape laying head through use of one or more of the disclosed guide tools. The surface of the guide tool includes small holes that allow for positive and negative air pressure to be applied to the surface to increase or decrease the friction between the tape that is passing over and being redirected by the surface.
