Analisi dell’anisotropia microstrutturale in materiali compositi rinforzati con fibre corte

A. Bernasconi, F. Cosmi, D. Dreossi


Synchrotron light microtomography has proved to be particularly efficient in order to analyze
the microstructural characteristics in terms of reinforce fibre distribution and orientation in glass fibre reinforced
composites. The spatial distribution of fibre within the polymeric matrix could be detected even in
case of fibre characterized by a small diameter (10 micrometers average diameter). Differences in orientation
distribution within a sample could be measured using the Mean Intercept Length (MIL) and the fabric
tensor. The results presented herein refer to a sample of a 30% by weight glass fibre reinforced polyamide 6,
extracted form a thin plate.
