Abstract
Systems for manufacturing a Stage 1 carbon-carbon (CC) part, including a resin infused with at least one of chopped fibers, milled fibers, or a continuous fiber. The resin further may include at least one UV initiator to render the resin UV gellable upon exposure to UV light. An additive manufacturing (AM) system determines and provides tool paths needed to provide an engineered characteristic to the Stage 1 CC part. A print nozzle component of the AM system extrudes the resin in accordance with the tool paths onto a sacrificial support material layer, such that the fiber(s) are deposited in desired orientations, within each layer, in a layer-by-layer printing operation. A UV light illuminates the resin after extrusion to initiate gelation of the resin as the resin is extruded onto the sacrificial material layer, to thus form a precursor part having an imparted or enhanced performance characteristic. A pyrolysis subsystem may be used for pyrolyzing the precursor part to create the Stage 1 CC part.
