Quantitative evaluation of void content in polymer matrix composites by means of X-ray computed tomography

Voids in modern polymer matrix composites (PMC) can significantly influence the mechanical properties of the final products and therefore play an important role in terms of quality assurance during the production process. As soon asthe parts become more complex and larger, there are nearly no manufacturing methods that guarantee void free parts. Therefore the development of products in combination with new manufacturing technologies and material systems or new material combinations requires a detailed materials characterisation. By using X-ray computed tomography (CT) methods, it is possible to receive a relatively fast impression of internal microstructural materials composition of a certain volume.
