Abstract
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.
Claims20
A method for manufacturing a carbon/carbon composite, the method comprising:
- extruding a polymer composite material using an extrusion deposition additive manufacturing process to form a preform, wherein the polymer composite material comprises a thermoplastic polymer reinforced with carbon fibers;
- and
- heating the preform via pyrolysis to form the carbon/carbon composite;
- and
- preserving a shape of the preform with a removable internal support during the step of heating.
