Abstract
A commingled fiber preform is provided. The commingled fiber preform includes a plurality of first fabric layers and a second fabric layer. The second fabric layer is positioned on top of the plurality of first fabric layers. The second fabric layer is joined to the plurality of first fabric layers via through thickness reinforcement (TTR) using a commingled thread. A transport depth of the TTR penetrates completely through a thickness of the second fabric layer and partially through a thickness of the plurality of first fabric layers. The commingled thread comprises carbon fibers commingled with fugitive fibers. The fugitive fibers are pyrolyzed from the commingled fiber preform to create a path through the thickness for infiltration of fluids.
