本试验探讨了用热压处理后的竹纤维板生产与单板层积材结构相似的竹材层积材的技术可行性。使用基于间苯二酚的粘合剂制造六个具有大约2 X 42 X 42 cm的尺寸的LBL板（由四层竹西风垫制成）。实验设计涉及三种组合的分层结构（类型I，II和III）和两个LBL加载位置（H型梁和V型梁）在弯曲试验。然后将这些材料与普通LVL进行比较。结果表明，LBL梁的抗弯性能（断裂模量和弹性模量）与LVL梁相当，但对3种LBL梁的物理力学性能影响不显著。有趣的是，将粘合线定向到垂直方向（V形梁）可以最大化LBL的极限强度。
This experiment explored the technical feasibility of using bamboo zephyr mat with pre-hot-pressed treatment for the manufacture of laminated bamboo lumber (LBL), which is similar in construction to that of laminated veneer lumber (LVL). Six LBL boards (made from four-ply bamboo zephyr mats) with approximate dimensions of 2 x 42 x 42 cm were fabricated using resorcinol-based adhesive. The experimental design involved three combinations of layered structures (types I, II, and III) and two LBL loading positions (H-beam and V-beam) during the bending test. These materials were then compared to ordinary LVL. Results indicated that the bending properties (moduli of rupture and elasticity) of LBL were comparable to those of LVL, but there was no significant effect on the physical and mechanical properties among the three types of LBL beam. Interestingly, orienting the glue line to the vertical direction (V-beam) could maximize the ultimate strength of the LBL.
