Abstract
An example method includes forming an interlayer on a carbon fiber fabric to form a composite fiber fabric. The interlayer comprises a binder. The method further includes winding the composite fiber fabric around a core to form a composite fiber preform comprising a plurality of layers defining an annulus extending along a central axis. The method further includes densifying the composite fiber preform.
Claims15
A method comprising:
- forming an interlayer on a carbon fiber fabric to form a composite fiber fabric, wherein the interlayer comprises a binder;
- winding the composite fiber fabric around a core to form a composite fiber preform comprising a plurality of layers defining an annulus extending along a central axis, wherein the interlayer is formed on the carbon fiber fabric without needling and prior to winding the composite fiber fabric, wherein a portion of carbon fibers of the carbon fiber fabric having a substantially in-plane orientation is greater than or equal to about 50%, wherein a portion of carbon fibers of the carbon fiber fabric having a substantially out-of-plane orientation is less than or equal to about 50%, wherein the out-of-plane orientation is parallel with a radial orientation of the composite fiber preform;
- and
- densifying the composite fiber preform.

A system comprising:
- a fabric source comprising a carbon fiber fabric;
- an interlayer source configured to form an interlayer on the carbon fiber fabric without needling and prior to winding the carbon fiber fabric and the interlayer, wherein a portion of carbon fibers of the carbon fiber fabric having a substantially in-plane orientation is greater than or equal to about 50%, wherein a portion of carbon fibers of the carbon fiber fabric having a substantially out-of-plane orientation is less than or equal to about 50%, wherein the out-of-plane orientation is parallel with a radial orientation of the carbon fiber fabric;
- and
- a winding apparatus configured to wind the carbon fiber fabric and the interlayer around a core to form a composite fiber preform and defining an annulus extending along a central longitudinal axis, the fiber preform comprising:
- a plurality carbon fiber fabric layers extending in an axial direction parallel with the longitudinal axis and a circumferential direction perpendicular to both the radial and axial directions, wherein each layer of the plurality of carbon fiber fabric layers comprises a plurality of elongate carbon fibers;
- and
- a plurality interlayers extending in an axial direction parallel with the longitudinal axis and a circumferential direction perpendicular to both the radial and axial directions, wherein the interlayer comprises a binder configured to mechanically bind one or more adjacent carbon fiber fabric layers.
