    Description

    The structural performance of medium density fiberboard (MDF) is attributable to three primary variables which are: physical and mechanical properties of individual wood fibers; fiber-to-fiber stress transfer; and fiber orientation. These origins of fiber properties and stress transfer can be traced to the fiber generation method wherein fiber orientation is associated with mat formation. This paper is part of an on-going study to determine the mechanisms governing the stiffness and strength of fiber-based composites. Preliminary data are presented in this paper focusing on the effect of juvenility and fiber generation on the mechanical properties of individual wood fibers and the subsequent properties of MDF panels. Development of panel stiffness and strength is also discussed with regards to fiber packing and stress transfer as determined by testing oriented and un-oriented panels as well as direct observation with microtomography.
