METHOD FOR FAST PROTOTYPING OF LARGE PARTS IN COMPOSITE MATERIAL WITHOUT MOLDS

摘要

A method for fast prototyping to create prototypes of large parts in composite material (typical dimensions are several metres). The method make it possible to obtain one or more prototypes without manual labor and without the requirement of the mold. The prototype, which can be made of the same material used for production and with the same mechanical properties of the final production part, can be also used as a 'one-off' piece, or to verify the suitability of the part before starting production, or as a dummy to create the mold used for production. The method makes use shaped created on light materials by automatic milling using CAD-CNC-CAM, which is then covered with a vacuum deformable thin film, that can act as superficial finish as well as detaching means.
