In this paper, a wood-based X-type lattice sandwich structure was manufactured via a type of insertion-glue method. Oriented strand board (OSB) was used as panel, birch was used as core and epoxy resin was used as adhesive. The compression behavior of the wood-based X-type lattice sandwich structure with different drilling depth (9 mm, 12 mm, and 15 mm), core spacing (12 mm, 30 mm and 48 mm) and core size (L50D8, L60D8) was investigated by a flatwise compressive test and a theoretical model was established to study the elastic constitutive relationship of the X-type lattice sandwich structure, including the equivalent compressive strength/modulus, and the specific strength. Results from the flatwise compressive test and the theoretical model showed that the failure modes of the wood-based X-type lattice sandwich structure were mainly shear failure of the core. The experimental values of compression modulus were less than the theoretical values. The deeper the depth of the drill hole, the shorter the core spacing, and the smaller the core size, the greater the compressive performance of the wood-based X-type lattice sandwich structure.

在本文中，通过一种插入胶法制造了木质的X型晶格三明治结构。定向刨花板（OSB）被用作面板，桦木被用作芯材，环氧树脂被用作粘合剂。具有不同钻孔深度（9 mm，12 mm和15 mm），芯间距（12 mm，30 mm和48 mm）和芯尺寸（L50D8，L60D8）的木质X型晶格三明治结构的压缩行为通过平面压缩试验进行了研究，并建立了理论模型来研究X型晶格夹心结构的弹性本构关系，包括当量抗压强度/模量和比强度。平板压缩试验和理论模型的结果表明，木质X型格构夹层结构的破坏模式主要是岩心的剪切破坏。压缩模量的实验值小于理论值。钻孔的深度越深，岩心间距越短，岩心尺寸越小，木质X型格状三明治结构的压缩性能越好。
