Balsa wood is an appropriate core material for structural sandwich applications due to its high strength- and stiffness-to-weight ratios. However, the mechanical properties vary considerably owing to the inherent scattering of natural wood materials. One approach to reduce this scatter and tailor the mechanical properties according to specific application needs is to recompose the natural material into a veneered material consisting of veneer layers of different grain orientations, which are adhesively bonded together. The mechanical properties of such a veneered balsa wood, composed of alternating 0°/90° grain orientations, were investigated at ambient temperature according to corresponding standards. The properties were significantly influenced by the orthotropy on the material scale within one veneer layer and on the system scale within the assembled veneer layers. Standardized experimental set-ups and specimen geometries may produce artifacts such as buckling or strain hardening which deviate from the material behavior in real structures. The thin adhesive between the veneer layers did not negatively affect the mechanical behavior since failure occurred within the veneer layers and not in the interfaces.

轻木由于具有很高的强度和刚度重量比，因此是结构三明治应用的合适核心材料。然而，由于天然木材材料的固有散射，机械性能发生很大变化。减少这种散射并根据特定应用需求调整机械性能的一种方法是将天然材料重新组合成单​​板材料，该单板材料由不同晶粒取向的单板层粘合在一起。根据相应的标准，在环境温度下研究了由0°/ 90°交替晶粒取向组成的这种单板轻木的机械性能。在一个饰面板层内的材料尺度上和在组装饰面板层内的系统尺度上，正交性对性能的影响很大。标准化的实验装置和样品的几何形状可能会产生诸如屈曲或应变硬化之类的伪影，这些伪影会偏离实际结构中的材料行为。单板层之间的薄粘合剂不会对机械性能产生负面影响，因为在单板层内部而不是在界面中会发生故障。
