摘要层叠单板（LSV）是一种新型工程木链复合材料，由层叠薄（3毫米）的层叠单板组成（见本研究的第一部分）。优点包括利用低密度的小直径木材，结构应用的良好机械性能，以及为特定的最终用途设计层压板的能力。本文探讨了薄链单板工程层压复合材料概念的可行性。测定了单股股线层和由股线层制成的层压制品的性能，并与基于经典层压理论（CLT）的传统木复合板性能和预测进行了比较。LSV复合材料的弹性和强度性能优于胶合板和由单板制成的层压单板木材复合材料，优于定向刨花板和刨花板。结果表明，CLT模型可用于工程复合材料铺层，可以近似地反映低电压复合材料的性能。其强度和刚度比小直径母材高100-150%。
Abstract Laminated strand veneer (LSV) is a new engineered wood-strand composite consisting of laminated thin (3 mm) strand veneers (see Part 1 of this study). Advantages include utilization of low-density small-diameter timber, good mechanical properties for structural applications, and the ability to engineer the lay-up of laminates for specific end uses. In the present paper, the feasibility of the concept of engineering laminated composites made of thin strand veneers is scrutinized. Properties of individual strand plies and laminated products manufactured with strand plies were determined and compared with traditional wood composite panel properties and predictions based on the classical lamination theory (CLT). Elastic and strength properties of LSV composites compare favorably with plywood and laminated veneer lumber composites made of veneer, and exceeded those of oriented strand board and particleboard. It was shown that the CLT model was useful in engineering composite lay-ups to give an approximation of LSV composites properties. Strength and stiffness of LSV are 100–150% higher than that of the small-diameter parent wood from which it was formed.
