Abstract: The present subject matter relates to composite carbon fiber sheets and methods for preparing the composite carbon fiber sheets. The composite carbon fiber sheet comprises a first carbon fiber sheet of a first weave and a second carbon fiber sheet of a second weave. A cut area is created in a first carbon fiber sheet of a first weave. A cutout is created from a second carbon fiber sheet of a second weave. The cutout is combined with the first carbon fiber sheet in the cut area to obtain the composite carbon fiber sheet.

Abstract: In one example, a privacy film may include a transparent film formed of a transparent build material and a clear fusion agent. Further, the privacy film may include a viewing angle interference gate pattern formed of the transparent build material and a black fusion agent. The viewing angle interference gate pattern may be formed within the transparent film.
