LAYERED CARBON FIBER PREFORM
A preform for a carbon-carbon composite including a plurality of fibrous layers superposed and needled-punched together. Each fibrous layer of the plurality of fibrous layers includes web fibers and tow fibers that each include at least one of carbon fibers or carbon-precursor fibers. The plurality of fibrous layers includes a first, a second, and a third fibrous layer, the third fibrous layer positioned between the first and the second fibrous layers. The third fibrous layer includes at least one of a ratio of web fibers to tow fibers that is less than a ratio of web fibers to tow fibers of the first fibrous layer, an areal weight that is greater than an areal weight of the first fibrous layer, or a pre-needled thickness that is greater than a pre-needled thickness the first fibrous layer.
