可塑杨木单板3D结构材制备与力学性能研究
Preparation and Mechanical Properties of 3D Structural Materials Made from Moldable Poplar Veneer
摘要
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.关键词
