A Characterization Study Relating Cross-Sectional Distribution of Fiber Volume Fraction and Permeability

Year: 2019

Type: conference-paper

Abstract: In the present study, Scanning Electron Microscopy (SEM) has been used to assess the influence of a varying cross-sectional fiber volume fraction on local permeability values.The investigated sample is a textured glass fiber reinforced polyurethane composite rod with an Ø5mm cross-section.The SEM investigations show a high variation in local fiber volume fraction with a mean fiber volume fraction of 0.41±0.2,which is in agreement with the value 0.41 obtained by burn-off test by the manufacturer.The additional result from the SEM investigations was a mean fiber diameter of 23.2±2.6µm,which was verified by single fiber tests.The characterization results were successfully used to evaluate the local variation in permeability over the cross-section and could most likely be a very essential input for numerical impregnation simulations.
