Methods of manufacturing carbon/carbon preforms and carbon/carbon composites formed therefrom. Such a method includes extruding a polymer composite material using an extrusion deposition additive manufacturing process to form a preform, and heating the preform via pyrolysis to form the carbon/carbon composite.

Methods of producing carbon/carbon composite preforms and carbon/carbon composites formed therefrom

Methods of embedding a heating circuit in an article fabricated by additive manufacturing. The methods describe techniques such as co-extruding a wire, capable of being heated, along with print material in additive manufacturing of the article, and placing a pre-shaped wire capable of being heated between adjacent layers of the article. A third method includes dispensing a wire, capable of being heated, during the additive manufacturing of the article, and compacting the wire into the printed material. An apparatus for embedding a heating circuit in an article fabricated by additive manufacturing. The apparatus contains a wire dispenser, a cutter to control the length of the wire dispensed, and a compactor capable of embedding the wire capable of being heated into the printed material. An article made by additive manufacturing is disclosed. The article contains at least one heating element embedded in the article during the additive manufacturing process.

A method of depositing a multiphase material. The method includes providing a Continuous Multifunctional Composite (CMC) phase containing at least one continuous element in a polymeric matrix, passing the CMC phase through a feeding system containing a cutting system, producing a predetermined length of the CMC phase, providing a flow a molten polymer such that the molten polymer and the CMC phase are merged into a continuous co-extrusion nozzle so as to produce a co-extruded multiphase material, and depositing the co-extruded multiphase material onto a surface. An apparatus for depositing a multiphase material. The apparatus contains a co-extrusion nozzle, a means to introduce a CMC phase and a molten polymer into the co-extrusion nozzle, such that the molten polymer and the CMC phase are co-extruded and deposited on a surface. An article containing a CMC phase containing continuous elements embedded in a polymer resin forming a multiphase structure.

The present disclosure provides a molding system for preparing a fiber-reinforced thermoplastic (FRT) composite article, including a molding machine; a mold disposed on the molding machine and having a mold cavity to be filled with a composite molding resin including a polymeric material having a plurality of fibers; a processing module configured to generate an anisotropic viscosity distribution of the composite molding resin in the mold cavity based on a molding condition for the molding machine; and a controller coupled to the computing apparatus and configured to control the molding machine with the molding condition to perform an actual molding for the composite molding resin. The anisotropic viscosity distribution of the composite molding resin is generated by taking into consideration an orientation distribution of the fibers in the composite molding resin.
