  In this paper, wood-based inclined lattice truss core sandwich structures made of poplar laminated veneer lumber、 birch dowels and polyvinyl acetate emulsion-isocyanate adhesive were manufactured using slotting and adhesive bonding approach.The shear behaviour of the structure were investigated under three-point short beam shear to explore the effect of the shear span-to-depth(a/D) on the results of shear performance and investigate the possibibility of sandwich beam theory of Allen in predicting the deflection response of wood-based inclined lattice truss core sandwich structures.

为探索木质纤维资源高效利用的新途径,本文提出了基于动态塑化-木塑复合之木质纤维塑性加工理念,系统地研究了木质纤维的动态塑化机理,初步建立了以木质纤维的动态塑化为基础、以木塑复合为基本途径的木质纤维塑性加工的理论体系。主要研究内容包括以下几个方面:(1)通过DMA采用粉末样品夹(MP-DMA)对木材纤维的动态粘弹性进行测试,揭示了离子液体(IL)氯化1-乙基-3-甲基咪唑([Emim] Cl)对木材
苯并噁嗪树脂具有优异的静态和动态力学性能、低的吸水率、高的热稳定性能和阻燃性能等,主要应用于汽车、航空航天和建筑工业材料[1]。天然苎麻纤维具有密度低、力学性能好以及可自然降解等特点,是绿色复合材料的理想增强材料。结合二者各自优势及协同作用,可望制备出高性能苯并噁嗪树脂复合材料。
