Abstract
An experimental method is developed to measure the three-dimensional fiber orientation in short fiber reinforced composites by utilizing an image processing
technique. The second order orientation tensor can be calculated with geometrical data that were obtained from two parallel planar cross-sections. The orientation state
of individual fibers is determined from the geometry of the elliptical cross-sectional shape on the polished surface.
The basic concept in determining the three-dimensional fiber orientation tensor is to slice the composite sample twice in the same direction within a small distance.
The tensor is determined by using a digital image processing technique and a computational code which calculates the tensor from the geometrical characteristics
obtained for the elliptical fiber cross-sections. Experiments are performed to measure the three-dimensional orientation tensor of composite specimens and good results are obtained by using the method proposed in this study
