DescriptionThe potential for substitution of structural wood composites into solid-sawn lumber markets is presented from the technological viewpoint. Technological limitations of existing composite processes and products are reviewed in the context of the present laminated veneer lumber (LVL), flakeboard, and fiber/ paper industries. The limits of mechanical property potential are presented to show that strength and stiffness may be enhanced through innovative processing of structural wood composites. The routes for introduction of these composites are presented as (1) direct substitution for solid-sawn lumber, (2) introduction of new materials and components, and (3) development of new structural systems for light-frame construction.
