Abstract
We report on the characterization of glass fiber-filled polypropylene compounds identified by means
of X-ray computed tomography and optical coherence tomography. During processing, the fibers can
adopt complex patterns of orientation, which influence the mechanical properties of the final product.
Gathering information about the flow behavior of polymer melts is important for the design of both
extrusion dies and extruded parts. We show the application of X-ray computed tomography and optical
coherence tomography to selected polymer extrusion examples. Samples with a variety of fiber volume
fractions, fiber lengths, and processing conditions were analyzed, and fiber orientation, distribution,
and concentration measured.
