摘要

以杨木单板为原料，通过脱木质素处理结合空气干燥和水浸工艺，制备具有优异折叠成型性能的塑性杨木单板。利用波浪状模具并结合组装工艺，最终制备模制木材和3D结构材。采用多种表征手段系统分析塑性杨木单板的宏/微观形貌以及3D结构材的结构稳定性和抗压强度。结果表明，塑性杨木单板在沿木纤维方向上表现出最大的拉伸强度为190.67 MPa，约是未处理单板的5倍；单层3D结构材的抗压强度为0.97 MPa，具有优异的结构稳定性和机械支撑力。通过层层组装制备的多层3D结构材具有轻质高强等优点，为木材的高值化利用提供了新思路。

Abstract

Moldable poplar veneer with the excellent folding formability was produced through delignification combined with air drying and water immersion processes. Molded wood products and 3D structural materials were created using a wavy mold and integrating a hot-press assembly technique. Various characterization methods were employed to analyze the macro- and micro-morphology of the moldable poplar veneer

as well as the structural stability and compressive strength of the 3D structural materials. The results showed that the moldable poplar veneer exhibited the superior tensile strength (190.67 MPa) in longitudinal direction of the wood

which were nearly five times that of untreated veneer. The compressive strength of a single-layer 3D structural material was about 0.97 MPa

demonstrating excellent structural stability and mechanical strength as a supporting component. Additionally

the multi-layer 3D structural materials

produced through layer-by-layer assembly

offer advantages such as lightweight and high strength

providing a novel approach to the high-value-added utilization of wood.
