1. A method for forming a carbon fiber preform, the method comprising:
- forming an array of carbon fiber filaments by extending a plurality of carbon fiber filaments between a bottom plate and a top plate, wherein each carbon fiber filament of the array of carbon fiber filaments extend in approximately a z-axis direction relative to an x-y plane;
depositing, via a print head of a three-dimensional printing system, a first plurality of carbon fibers on the bottom plate to form a first layer of carbon fibers in approximately the x-y plane, wherein the first plurality of carbon fibers are deposited around and between carbon fiber filaments of the array of carbon fiber filaments; and
depositing, via a print head of a three-dimensional printing system, a second plurality of carbon fibers on the first layer of carbon fibers to form a second layer of carbon fibers in approximately the x-y plane, wherein the second plurality of carbon fibers are deposited around and between carbon fiber filaments of the array of carbon fiber filaments extending in approximately the z-axis direction relative to the x-y plane, wherein each carbon fiber filament of the array of carbon fiber filaments extends completely through both the first and second layers of carbon fibers.

12. A carbon fiber preform comprising:
-
a first layer of carbon fibers formed by depositing, via a print head of a three-dimensional printing system, a first plurality of carbon fibers and a first resin binder in approximately an x-y plane, the first resin binder configured to bind the first plurality of carbon fibers to form the first layer of carbon fibers; a second layer of carbon fibers formed by depositing, via a print head of a three-dimensional printing system, a second plurality of carbon fibers and a second resin binder in approximately an x-y plane on the first layer, the second resin binder configured to bind the second plurality of carbon fibers to form the second layer of carbon fibers; and an array of carbon fiber filaments extending in approximately a z-axis direction relative to the x-y plane, wherein the first plurality of carbon fibers and the second plurality of carbon fibers are both deposited around and between carbon fiber filaments of the array of carbon fiber filaments, wherein each carbon fiber filament of the array of carbon fiber filaments extends completely through both the first and second layers of carbon fibers. - View Dependent Claims (13, 14, 15, 16, 17, 18)
