20090014919 | AGGREGATE-BASED MANDRELS FOR COMPOSITE PART PRODUCTION AND COMPOSITE PART PRODUCTION METHODS - A method for forming a composite structure, using a mandrel that is later removed from the composite structure, involves production of a mandrel by depositing a particulate mixture, including an aggregate and a binder, into a mold and removing the mandrel from the mold. The mandrel may be treated while still in the mold by heating, curing with an agent, microwave energy, or by some combination thereof. Once finished, the mandrel can be used in manufacturing polymer and/or composite components. The mandrel can also be include materials that can be easily removed from the finished composite structure by water, shakeout, chemically dissolving, or by some combination thereof. | 01-15-2009 |
20100237531 | Method of Fabricating Three Dimensional Printed Part - A method of fabricating a three-dimensional printed part includes injecting a powder layer with an aqueous solution and curing the powder layer by depositing an acid gas on the powder layer to form a rigid structure. | 09-23-2010 |
