US Patent:

7678307, Mar 16, 2010

Filed:

Nov 3, 2006

Appl. No.:

11/592660

Inventors:

Ervin Geiger - Columbia City IN, US

Assignee:

Materials Innovation Technologies, LLC - Fletcher NC

International Classification:

B29B 1/26
D21F 13/00

US Classification:

264 87, 162218, 425272

Abstract:

A molding head is especially adapted for vacuum molding or forming of structures and, in particular, fibrous composite structures in an adjustable, controllable three dimensional orientation before, during and after molding. Such a molding head includes a mold plate with narrow slots in the mold surface thereof and wider channels in the back surface thereof, with such slots and channels intersecting one another. A control system of servomotors or other actuators permits movement and orientation of the mold head during forming, thereby creating the ability to vary the material properties based on gravity and particle or suspension grain, thickness and other now controllable properties.

Abstract:

A molding tool is especially adapted for vacuum molding or forming of structures and, in particular, fibrous composite structures. Such a molding tool includes a mold plate with narrow slots in the mold surface thereof and wider channels in the back surface thereof, with such slots and channels intersecting one another. The slots and channels are arranged so as to promote an effective, uniform distribution of a vacuum on the mold surface of the mold plate yet not promote deformation and/or dimpling of a part being formed upon the mold surface. A skirt is advantageously provided on the mold plate to facilitate the deposition of the structure material from a suspension during the vacuum molding procedure.
