Title
(EN) ZIP STRIPS FOR MOLDING OF INFUSED FIBERGLASS PRODUCTS
(FR) BANDES DE FERMETURE À GLISSIÈRE POUR LE MOULAGE DE PRODUITS EN FIBRE DE VERRE INFUSÉS
Abstract
(EN) A method of removing a vacuum bag from a composite mold. Removable strips are placed around the perimeter of the component parts and across the parts to create natural break points in the consumable materials used during manufacture of a composite product, e.g. wind turbine blade. The vacuum bag, and other consumable layers, are placed over the removable strip such that when the strips are pulled, the strip tears, in a controlled and complete manner, through each layer of consumables. This eliminates the need to use a knife/scissor to remove the finished product, thereby avoiding risk of injury.
(FR) L'invention concerne un procédé de retrait d'un sac sous vide d'un moule composite. Des bandes amovibles sont placées autour du périmètre des parties d'élément et sur l'ensemble des parties pour créer des points de rupture naturels dans les matériaux consommables utilisés pendant la fabrication d'un produit composite, par exemple une pale d'éolienne. Le sac sous vide, et d'autres couches de consommables, sont placés sur la bande amovible de telle sorte que, lorsque les bandes sont tirées, la bande déchire, d'une manière contrôlée et entière, chaque couche de consommables. Ceci élimine la nécessité d'utiliser un couteau/des ciseaux pour retirer le produit fini, évitant ainsi le risque de blessure.
