Abstract
A commingled fiber preform is provided. The commingled fiber preform includes at least one first fabric layer and a second fabric layer. The second fabric layer is positioned on top of the at least one first fabric layer. The second fabric layer is joined to the at least one first fabric layer 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 an entirety of the at least one first fabric layer. 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.
