Abstract
The introduction of short, tilted rods to reinforce polymer composite laminates has resulted in near doubling the strength of lap shear specimens. Paperboard is predominantly a multi-layered structure, similar to composite laminates in many ways. Improved bonding between layers should have a positive influence on mechanical performance. Tilted fibers, or z-direction oriented fibers, can improve performance by bonding non-adjacent plies. Presence of fiber tilt should enhance shear and compression behavior without additional fiber. Our goal in this work was to test for the existence of fiber tilt in paperboard using directionally sensitive mechanical and optical tests, and to measure its effect on important mechanical properties.
