A procedure is described for obtaining information concerning the circularity of fiber cross-sections from measurements made in a longitudinal view of the fibers. A method is developed for viewing and measuring the projected diameter of fibers viewed longitudinally, and an analytical procedure is described for analyzing these measurements to determine the flatness or roundness of the fiber cross-sections. Experimentation conducted to test the reliability of these procedures is discussed as these methods are used to measure numerous different samples of fibers of known and varied cross-sectional shapes and sizes.
