Abstract

In some examples, the disclosure describes a method including depositing a first layer including a resin and at least one of a carbon fiber or a carbon fiber precursor material on a work surface of a three-dimensional printing system, carbonizing at least the resin of the first layer using a carbonizer attached to the three-dimensional printer to form a first layer of carbon-carbon composite including carbon fibers and carbonized matrix material, depositing an additional layer including a resin and at least one of a carbon fiber or a carbon fiber precursor material of material on the first layer of carbon-carbon composite, and carbonizing at least the resin of the additional layer using the carbonizer to form an additional layer of carbon-carbon composite on the first layer of carbon-carbon composite.

First claim

What is claimed is:

1. A method comprising:
depositing a first layer of material on a work surface of a three-dimensional printing system, wherein the first layer of material comprises a resin and at least one of a carbon fiber or a carbon fiber precursor material, and wherein depositing the first layer of material comprises depositing the resin on the work surface via at least one print head of the three-dimensional printing system;
carbonizing the resin of the first layer of material to form a first layer of carbon-carbon composite comprising carbon fibers and a carbonized matrix material, wherein carbonizing the resin comprises carbonizing localized sections of the resin of the first layer of material using a carbonizer of the three-dimensional printer system to convert the resin to the carbonized matrix material;
depositing an additional layer of material on the first layer of carbon-carbon composite, the additional layer of material comprising the resin and at least one of the carbon fiber or the carbon fiber precursor material, and wherein depositing the additional layer of material comprises depositing the resin on the first layer of carbon-carbon composite via the at least one print head of the three-dimensional printing system; and
carbonizing localized sections of the resin of the additional layer of material using the carbonizer to convert the resin of the additional layer of material to the carbonized matrix material.

2. The method of claim 1 , wherein depositing the first layer of material comprises:
depositing a fiber layer of the at least one of the carbon fiber or the carbon fiber precursor material; and
depositing the resin on the fiber layer via the at least one print head of the three-dimensional printing system.

3. The method of claim 2 , wherein depositing the fiber layer of the at least one of the carbon fiber or the carbon fiber precursor material comprises depositing the fiber layer via the at least one print head of the three-dimensional printing system.

4. The method of claim 1 , wherein depositing the first layer of material comprises:
coating a carbon filament with the resin to form a coated carbon filament, wherein the carbon filament comprises the at least one of the carbon fiber or the carbon fiber precursor material; and
depositing the coated carbon filament on the work surface of a three-dimensional printing system via the at least one print head of the three-dimensional printing system to form the first layer of material.

5. The method of claim 1 , wherein carbonizing localized sections of the resin of the first layer of material using the carbonizer comprises carbonizing localized sections that define an area of about 0.1 mm to about 10 mm in diameter.

6. The method of claim 1 , wherein the carbonizer comprises at least one of a focused plasma torch, a concentrated laser, or an induction heat source.

7. The method of claim 6 , wherein carbonizing localized sections of the resin comprises, heating a localized area of the resin via the carbonizer to a temperature above about 450 degrees centigrade to convert the resin of the localized area of the resin to the carbonized matrix material.

8. The method of claim 1 , wherein depositing the additional layer of material and carbonizing localized sections of the resin of the additional layer of material comprises repeatedly depositing the additional layer of material and carbonizing localized sections of the resin of the additional layer of material to form at least about 15 layers of carbon-carbon composite.
