WebThe parameter α is the fiber orientation factor. For synthetic fibers, it has been reported that a three-dimensional random fiber alignment yields an α value of 1/5, planar randomly oriented fibers yield a value of 3/8, and fibers aligned axially with the load yield a value of 1 (Bailon and Dorlot 2000; Gibson 2007). WebDuring testing, images of the specimens were acquired to determine the occurrence of fiber breakage, bond deformation, and bond cohesive failure. Maximum force, stiffness, and orientation parameters were found to be significantly different among the three specimen groups (p < 0.01) but the relative basis weight was not (p > 0.01).
