I disagree. In advanced materials, we analyze materials categorically. In this instance, the way we would calculate the structure of wood is based on its isotropy, or more simply, its symmetry of strength and stiffness. The way wood behaves anisotropically means its structure is calculated the same way as most other composites. Composite Laminate Theory is the primary way that structure behavior is calculated for both wood laminates and carbon fiber laminates. We squarely categorize it in the same bin as carbon fiber, but that's just one perspective from one discipline, so take it as you will.
