“…This procedure enabled the fast analysis of a large amount of fibers, reduces operator bias, and can be used to generate overall views of the entire cross-section of a given sample. 15 This last aspect is of great interest when inhomogeneous materials, like composites, or elements with very large shape and size distributions are under analysis, such as lignocellulosic fibers.…”

Lignocellulosic fibers have several advantages as reinforcement for polymer-matrix composites such as their biodegradability and neutrality with respect to CO 2 emission. One characteristic of these fibers is the variability of their properties that usually present large bounds due to several factors. In respect to the determination of fiber properties, one issue is the actual measurement of the fiber cross-section. It is usual practice to measure a typical cross-section length and to assume that the fibers have circular cross-sections, although this is known to be a relatively crude approximation. In this work, digital microscopy and image analysis were used to measure the actual cross-section of several lignocellulosic fibers. The true area was compared to those calculated from minimum and maximum projected diameters, and the errors were analyzed.
